A USB flash drive is composed of flash memory data storage device consisting of a USB (universal serial bus) 1.1, 2.0 or 3.0 interface. USB flash drives are usually removable and rewritable, which are smaller than a floppy disk and most weigh less than 30 g (1 oz). With the increase in size and value, storage capacity can be up to 256 GB in 2009. Some allow 1 million right or erase bicycles. And they have a 10-year data retention cycle.

The use of a USB flash drive is often done with the same purpose which was intended to make floppy disks. Due to not moving parts, they are relatively small, fast, thousands of times more capable and they are less durable and reliable. By approximately 2005, most desktop and laptop computers were supplied with a floppy disk drive, but most devices have recently abandoned floppy disk drive adopting a USB port.

Flash drives use the USB mass storage standard, which are supported locally by modern operating systems such as Microsoft Windows, Mac OS X, Linux and Unix-like systems. USB drives with USB 2.0 and 3.0 support can store more data and transmit data faster than a very large optical disk drive and can be read by most other systems such as PlayStation 3.

Nothing moves mechanically in a flash drive; The drive word is created because the computer reads and writes flash drives data using a system command used for a mechanical disk drive, where this storage is another drive in the computer's operating system and the user interface. Is displayed. Mechanically flash drives are very strong and can face anything that does not really break the circuit board or connector.

Flash drive is composed of a small printed circuit board, which has circuit element and a USB connector, which is secured separately from electricity and is safe in a plastic, metal, or rubber shell, for example, in pocket or key Can be kept with the chain. The USB connector can be protected by a removable cap or by limiting the body of the drive, although it is unlikely to be damaged even when unsafe. Most flash drives use a standard type-A USB connection that allows them to be plugged into a port on a personal computer, but drives are also available for other interfaces.

Most USB flash drives receive their power from a USB connection and they do not need a battery. Some devices that combine the functionality of a digital audio player with the storage of flash drive type, require a battery for player purpose.

The technology मुख्य लेख : Flash memory और USB

Combines many old technologies with flash memory, low cost, low power consumption and small size, which is possible in the field of microprocessor technology until progress is made to the latest. Memory storage was based on earlier EPROM and EEPROM technology. All of them had very limited capacity, were slow for reading and rating, they needed complex high voltage drive circuits and could only be writed right after wiping all the contents in the chip.

Hardware designers later developed EEPROM with the extinction area divided into small "fields" which could be erased alone without affecting others. Changing the contents of a particular storage space involves copying the entire field in the off-chip buffer memory, erasing the field, modifying the required data in the buffer and re-writing it in the same field. This requires a lot of computer support and PC-based EEPROM flash memory system often holds its own dedicated microprocessor system. Flash drive, commobase is the subtle version of this.

The development of high-speed serial data interfaces such as USB made semiconductor memory systems with serial access storage made viable, along with the development of small, high-speed, low-energy microprocessor systems included in a very intensive system Designed to be able to Gradual access requires comparatively less power connection to memory chips than parallel access, which has simplified the creation of multi-gigabyte drives.

Computer access to flash memory system is very similar to some hard disk drives, where the controller system has complete control over where the information is actually stored. The actual EEPROM writing and eraser processes, however, are still much the same as the ones described above.

Many low cost MP3 players only add additional software and a battery to a standard flash memory control microprocessor so that it can act as a music playback decoder. Most of these players can be used as a conventional flash drive for any type of file storage. History First commercial product

Trek Technology and IBM started commercially selling the first USB flash drive in 2000. Singapore's Track Technology sold a model called "ThunderDrive" and IBM marketed the first drive from its product "Diskonkey" in North America (which was produced by Israeli company M-Systems) IBM's USB flash drive , Was available on December 15, 2000, and had a storage capacity of 8 MB, which was five times the capacity of the common floppy disk at that time.

In 2000, Lexar introduced a Compact Flash (CF) card with a USB connection and a partner card read / writer and USB cable, which eliminated the need for a USB hub.

In 2002, Netac Technologies, a Shenzhen consumer electronics company that claims to invent a USB flash drive in the late 1990s, was given a Chinese patent for this device.

Both Track Technology and Netac Technologies have tried to protect their patent claims. The track won a Singapore lawsuit, but a British court canceled a UK patent on track. While Netac Technology has sued PNY Technologies, Lenovo, Aigo, Sony, and Taiwan's Acer and Tai Guen Enterprise Co, most of the companies that produce USB flash drives tend to ignore such tracks and Netac patents . Second generation

The modern flash drive has USB 2.0 connectivity. However, they currently do not use full 480 Mbit / s (60MB / s) USB 2.0 Hi-Speed ​​specification support due to technical restrictions contained in NAND Flash. Most fast drives currently available use a double channel controller, although they are still far behind with the current transfer rate from the current hard disk or the maximum high speed USB throughput.

The entire file transfer speed varies greatly and should be checked before purchasing. The speed can be given in Mbyte per second, Mbit per second, or optical drive multipliers, such as "180X" (180 times 150 KiB per second). Some special fast drives claim to read up to 30 megabytes / s and write on it and its width. Old "USB Full Speed" 12 Mbit / s devices are limited to 1 MB / s. Design and implementation

A single mail type- A USB connector is fitted at one end of the device. There is a small printed circuit board inside the plastic shell. There are some power circuit arrangements on this board and there are some integrated circuits (ICs) created on the surface. Typically, one of these ICs provides an interface for the USB port, the other drives onboard memory and another flash memory.

The drives usually use the USB mass storage device to communicate with the host. Necessary components

Generally there are four parts of a flash drive: Additional components

A common device may also include: Packaging size and style Flash, various heavy or innovative drives, come in shape and size, in this case ikura sushi

Some manufacturers try to make their products different from the use of detailed housing, which are often heavy and cause problems in connecting the USB port for the drive. Since USB port connectors are often at a near distance on a computer housing, plugging a flash drive into a USB port may cause an adjacent port block. If a different extension is sold with a cable, such devices can only have a USB logo.

The USB flash drive is integrated into other carrying items, such as watches, pens, and even in the Swiss military knife; Others have been fitted with novelties such as toy cars or LEGO bricks. The small size, robustness and low cost of the USB flash drive is making it an increasingly popular peripheral for hair modification.

Heavy or large flash drive packaging can have poor performance when installed directly in a USB port; It can be corrected using a USB extension cable. Such cables are USB-compatible, but do not conform to the USB standard. File system मुख्य लेख : Flash file system

Most flash drives are sent with FAT or FAT 32 file system pre-format. The ubiquity of this file system allows the drive to access on almost any host device with USB support. In addition, standard FAT maintenance facilities (such as ScanDisk) allow repairs or retrieval of contaminated data. And since a flash drive, host system appears to be a USB-connected hard drive, the drive can be reformated in any file system supported by the host operating system. Defragmenting: The flash drive can be defragmented, but it does not get much profit as there is no mechanical head rotating the fragment from the fragment. Flash drives often have a larger internal sector size, i.e. defragmenting means less access to sector. Defragmenting reduces the life of the drive by making many unnecessary writes. [6]

Sam Delivery: Some file systems are designed to distribute usage on an entire memory device, regardless of any part (for example, for a directory); This equal distribution enhances the life of simple flash memory devices. In order to prolong the life of the device in some USB flash drive, this functionality is built into the software controller, while not in others, so the end user should see the specifications of their device before changing the file system for this reason. [7]

Hard drive: Sectors are 512 bytes long for compatibility with hard drives and the first sector may include a master boot record and a partition table. Therefore USB flash units can be divided into hard drives. Counterfeit product

The fake USB flash drive is quite common. These are usually low capacity USB drives that are modified so that they can overtake a large capacity drive (e.g., a 2GB drive being marketed as an 8GB drive). When a computer is plugged in, they show themselves as big capacity as they were sold, but when the data is written on them, either Wright fails, or the drive gets accumulated. , Or he writes a right over one. Software tools are available to detect and detect fake USB drives. Use चित्र:Ubutnu-USB-lanyard.jpg Lanyard with USB Flash Drive Personal data transport

The most common use of flash drives is the transport and collection of individual files such as documents, photos and videos. Some people keep medical alert information on MedicTag flash drives for use in emergencies and for disaster preparation. Safe storage of data, applications and software files

With the widespread deployment of flash drives used in different environments (safe or otherwise), the issue of data and information security remains of utmost importance. With the need for increased security of data, biometrics and encryption are becoming standard; OTFE systems such as FreeOTFE and TrueCrypt are particularly useful in this regard, because they can encrypt large amounts of data transparently. In some cases, a secure USB drive can use a hardware-based encryption system that uses a hardware module instead of software to encrypt the data firmly. System administration

Flash drives are especially popular among system and network administrators, which load them with configuration information and software used for system maintenance, troubleshooting and recovery. They are also used in the infected PC as the medium of the transfer of antivirus and recovery software, under which they allow a portion of the host machine's data to be stored. Since the storage capacity of the drive has increased, they have replaced the need for placing many CD ROMs and installers, which were needed to reinstall or re-update a system. Application carrier

Flash drives are used to carry applications that are run without installation on the host computer. Although in principle any standalone application can be used in such a way, many programs store data, configuration information, etc. on the hard drive and registry of the host computer.

The U3 company works with the drive manufacturers to provide custom versions of Microsoft Windows applications, from a special flash drive (the parent company SanDisk as well as others); When appended to a computer running Windows, the U3-compatible device is designed to auto-load a menu. The application should be modified for U3 platform so that it does not leave any data on the host machine. U3 also provides a software framework for independent software vendors interested in its platform.

Ceedo is an alternative product in which the main difference is that it does not need to modify the Windows application to run and carry it on the drive.

Similarly, other application virtualization solutions and portable application builders, such as VMware ThinApp (for Microsoft Windows) or RUNZ (for Linux), can be used to run software from a flash drive.

A wide range of portable applications can be found in the list of portable software, which is free and is capable of leaving the host computer running on a host computer's drive or registry without having any storage. Computer forensics and law enforcement

A recent development in the use of USB flash drives as an application carrier is the online forensic acquisition acquisition (COFEE) application of computers developed by Microsoft. COFEE is a set of applications designed to detect and remove digital evidence on seized computers with suspects. There should not be any change in information stored on the computer being tested by forensic software; Other forensic suites run from the CD-ROM or DVD-ROM, but they can not collect storage on the media they are running (although they can write on other attached devices such as external drives or memory stick). Operating system booting

Most existing PC firmware allow booting from a USB drive, under which they allow the launch of an operating system from a bootable flash drive. Such a configuration is known as Live USB.

While a live USB can be used for general purpose applications, size and memory decay makes them poor choices in comparison to the options. They are ideally suited for special purpose or temporary work, such as: Microsoft Windows Vista and Windows 7 ReadyBoost

In Windows Vista and Windows 7, the ReadyBoost feature allows the use of flash drives to increase the operating system memory. audio player

Many companies make digital audio players of small concrete conditions and essentially produce flash drives with sound output and a simple user interface. Examples include Creative MuVo, Philips GoGear and iPod Shuffle. Some of these are true USB flash drives as well as a music player; Other general-purpose data storage is not supported.

Many extremely small players operate with a permanently fit rechargeable battery charging from the USB interface. Music storage and marketing

Digital audio files can be moved from one computer to another, just like any other file and can be played on a compatible media player (with cavities for DRM-locked files). In addition, many home Hi-Fi and car stereo head units are now available with a USB port. It allows a USB flash drive containing various formats to be played directly in those devices that support its formats.

Artists sold or left the USB flash drive, whose first example is seen in 2004 when German band WIZO released "Stick EP", only as a USB drive. Apart from the five high-bitrate MP3s, there was also a video, image, song and guitar tablet included. Following artists including Kenny West, Nine Inch Nails, Kylie Minogue and Ayumi Hamasaki released music and promotional material on the USB flash drive. In 2009, a USB drive with fourteen incremental albums of Beatles was released in both FLAC and MP3. In arcade

In the arcade game In The Groove, more commonly, flash drives are being used in In The Groove 2 for the transfer of high scores, screenshots, dance edits and combos throughout the session. As well as software modification 21 (R21), custom songs can also be stored in the player and they can be played on any machine on which this feature is enabled. While the use of flash drives is common, the drive must be compatible with Linux.

A specially manufactured flash drive is used as a "save file" in arcade games, pump it up NX2 and pump it up NXA, as well as progress in the game's WorldMax and Brain Shower sections Is also done.

In the arcade game Dance Dance Revolution X, Konami created a special USB flash drive for the convenience of linking its Sony PlayStation 2 counterpart. Brand and Product Promotion

The availability of affordable flash drives has enabled them to be used for promotion and marketing purposes, especially for the technical and computer industry circles (such as the Technology Trade Show). They can be given for free, can be sold in less than the wholesale price, or can be included as a bonus with any other purchased product.

Usually, to increase mind share and brand awareness, custom-stamps are placed in a form of advertising such as Drive Company logo. This drive may be pre-loaded with an empty drive, or graphics, documentation, web link, flash animation or other multimedia and can be a free or display software. Some preloaded drives are read-only; Others are configured with read-only and write-protected partitions. Dual-partition drives are more expensive.

Flash drives can be installed to launch stored presentations, websites, articles and any other software automatically, for which the AutoRun feature of Microsoft Windows has to be used after inserting the drive. Autoruning in this way of software, does not work on all computers and is usually disabled by security-aware users. Backup

Some value-added resellers are now using a flash drive as part of a small-scale turnkey solution (e.g., point-of-sale system). Drive is used as a backup medium: Every night at the end of the drive the drive is inserted and a database is saved on the backup drive. Alternatively, the drive can be dropped on the business day and the data can be updated regularly. In both cases, the drive is removed at night and separated from the site.

It is also easy to lose these small devices and it is easy to unauthorize people to get an illegal backup. advantages and disadvantages Benefit

The stored data on the flash drive is impermeable with dust and scratches and flash drives are mechanically strong enough, due to which they are readily available and readily available for carrying the data from one place to another. Most personal computers support USB. Until 2009,

Flash drives also collect data in a dense form compared to many transferable media. In the middle of 2009, 256 GB drives became available, which has the ability to store more data than a DVD and even Blu-ray discs.

Compared to the hard drive, flash drives use less power, their moving objects are not fragile, and are small and light for less capacity.

Flash drives implement the USB mass storage device class so that most modern operating systems can read and write them without installing the device driver. Flash drives present an easy block-structured logical unit for the host operating system and keep the personal complicated implementation information of different underlying flash memory devices hidden. The operating system can block any file system usage or addressing scheme. Some computers can boot from a flash drive.

Some flash drives keep their memory even after being drowned in water, even after a machine wash, although this is not a design feature and should not be trusted. Before inserting the electric current, the flash drive should be removed and dried and it has been seen that it continues to work without any problems in the future. Channel V's gadget show cooked a flash drive in propane, deposited it in dry ice, immersed in various acidic fluid, crushed with a jeep and stamped it on a wall by a mortar. A company specializing in reducing lost data from a computer drive is able to re-extract all the data in the drive. Using optical or magnetic techniques, all data was lost on other removable storage devices that were tested. loss

Like all other flash memory devices, before the flash drive fails, only a limited number of writs can pass through the erase cycle. This should be noted while running a software or operating system through a flash drive. In order to correct space deficiencies as well as to fix space shortcomings, some developers have created special versions of the operating system (such as Linux in Live USB) or commonplace applications (like Mozilla Firefox) that are designed to run with flash drives. They were specifically customized for size and were configured to have temporary or intermediate files in the main RAM of the computer, instead of storing them temporarily on a flash drive.

Most USB flash drives do not include a write-protected mechanism, although some have a switch on the housing of the drive, which prevents host computers from modifying data on the drive. Right-protection, without the risk of transmitting a USB flash drive to a device, makes the virus suitable for repairing infected host computers.

One small drawback of small size is that they are easily placed here, lost somewhere or otherwise lost. If the data inside them is sensitive then this is a special problem (see data security). As a result, some manufacturers have added hardware encryption to their drives - even though the software encryption system does the same and is universally available for all USB flash drives. In the case of others, there is a possibility of applying with keychain, necklace and lanyard.

Compared to other portable storage devices, for example in the external hard drive, USB flash drives have a high cost per unit of storage and are available only in relatively small capacities; But the hard drive has a relatively high minimum value, so in small capacities (16 GB and less), the USB flash drive is much less expensive than the smallest available hard drive. Comparison with other portable storage Tape

Applications of existing data tape catridges rarely overlap the application of flash drives: drives and media are expensive, have very high capacity and very fast transfer speed and keep the data according to the sequence. While disk-based backups are the primary medium of choice for most companies, tape backups are still popular for taking data off-site for worse case scenarios. See LTO tape. floppy disk Comparing the size of a flash drive and a 3.5-inch floppy disk

Floppy disks are hardly fit in modern computers and they are obsolete for general purposes, although the internal and external drives can be installed when needed. Floppy disks can be a method of choice for transferring data from an old computer without booting without USB or floppy disks and so sometimes their use, for example, is done to make changes to the firmware on the BIOS chip. Removable storage devices such as the old Yamaha Music Board are also dependent on floppy disks, which require a computer to process. New equipment is being built with the support of USB Flash Drive. Optical media

There are various rights and rewritable forms of CD and DVD, portable storage media supported by most computers as of 2008. CD-R, DVD-R and DVD + R can be written only once, RW varieties up to 1,000 eras / wright cycle, while modern NAND based flash drives often run 500,000 or more eras / wright cycles. DVD-RAM discs are most suitable for data storage with more rewriting.

The optical storage device is one of the cheapest methods of mass storage after hard drives. They are slower than their Flash-based counterparts. Standard 12 cm optical discs are larger than flash drives and they are more susceptible to damage. Small optical media also exist, such as enterprise card CD-R, whose dimensions are similar to a credit card and have a slightly less easy but high capacity 8 cm recordable CD / DVD. Smaller discs are more expensive than standard size and do not work in all drives.

The Universal Disk Format (UDF) version 1.50 and above have the feature to support rewritable disks such as the Sparing table and Virtual Allocation Table, which disseminates usage on the entire surface of a disk and increases the age , But many older operating systems do not support this format. Packet-writing features such as DirectCD and InCD are available, but produce such discs that are not universally readable (though depending on the UDF standard). The Mount Rainier standard, by removing the old file system over it, and defect management for those standards, removes this flaw in the CD-RW media, but it requires support from both the CD / DVD burner and the operating system. is. Many of today's drives do not support Mount Rainier and older operating systems, such as older than Windows XP and Linux Kernel 2.6.2, do not support it (do later versions). Essentially, the CD / DVD is a great way to record huge information reserves, and there is also the advantage of being readable by most standalone players, but they are weak in doing small changes for a large collection of information. The ability of flash drives to do this, gives them a major edge over optical media. Flash memory card

Flash memory cards, such as secure digital cards, are available in various formats and capabilities and are used by many consumer devices. However, while almost all PCs have USB ports that allow the use of a USB flash drive, memory card reader is not normally supplied as a standard device (especially with desktop computers). Although there are cheap card reader available which can read many common formats, but there are two pieces (card and reader) instead of one of the portable devices.

Some manufacturers, who are looking for "best of both worlds" solutions, have created card readers who reach the size and form of USB flash drive (such as Kingston MobileLite, SanDisk MobileMate), these readers, memory cards Are limited to a specific subset of formats (such as SD, microSD, or memory stick) and often completely consolidate the card, so if they are not quite similar to a flash drive, then they And give portability. However, the combined cost of a mini-reader and a memory card will usually be slightly higher than the same USB flash drive, the reader + card solution provides additional flexibility in usage and actually has "unlimited capability" data. / p>

An additional benefit of the memory card is that many consumer devices (such as digital cameras, portable music players) can not use a USB flash drive (even if the device has a USB port) while the memory card used by the devices , Can be read by a PC with a card reader. External hard disk मुख्य लेख : External hard disk drive

Existing USB hard drives have become widely available and cheap, especially with the advent of USB. External hard disk drives are currently cost-per-gigabyte compared to flash drives and are available in wide capacities. Some hard drives support alternative and faster interfaces than USB 2.0 (e.g. IEEE 1394 and eSATA). For Right and Continuous Sector Reed (for example, from an unbroken file), most hard drives can provide continuous data rates more than current NAND flash memory.

Unlike solid-state memory, the possibility of damage to hard drives by shaking is more likely, such as falling from lower altitude, there are limitations of use at very high altitudes and all are vulnerable to magnetic media when the powerful magnetic field Despite being shielded by the cover, it is made aware. Hard drive is bigger and heavier in terms of total mass, compared to flash drives, although sometimes hard drives are harder in weight per unit of disk storage. Hard disks also suffer from file fragmentation, which can reduce the speed of access. Obsolete device

Audio tape cassettes are no longer used for data storage. Other types of high-capacity floppy disks (such as an animation superdisk) and drives with removable magnetic media, such as Lomaega Zip and Jazz Drive are now roughly obsolete and are rarely used. There are products in today's market that will match these legacy drives for both tape and discs (SCSI1 / SCSI2, SASI, Magneto Optic, Ricoh Zip, Jazz, IBM3590 / Fujitsu 3490E and Barnauli) the position of the art compact flash storage devices In - CF2SCSI. Encryption

In the form of high portable media, USB flash drives are easily lost and stolen. Content of all USB flash drives can be encrypted using third party disk encryption software such as FreeOTFE and TrueCrypt or programs that can use encrypted archives such as ZIP and RAR Some of these programs can be used without installation. Executable files can be stored on USB drive, with encrypted file image. The encrypted partition can then be accessed from any computer running the correct operating system, although for this, the user must have administrative rights on the host computer to access the data.

Other flash drives allow the user to configure different sizes of secure and public partitions and present hardware encryption.

New flash drives support biometric fingerprinting for confirmation of user identity. In mid-2005, this was a costly option for standard password protection available on several new USB flash storage devices. Most fingerprint scanning drives depend on the host operating system to authenticate fingerprint through a software driver and often limit the drive to Microsoft Windows computers. However, there are USB drives with fingerprint scanners that use the controller that allow the use of secure data without any authentication.

Some manufacturers deploy physical authentication tokens as a flash drive. These are used to control the access of a sensitive system, including the encryption key, and more commonly, to communicate with the security software on the targeted machine. The system has been designed such that the target machine does not work unless the flash drive is inserted. Some of these "PC Lock" devices also work as normal flash drives when installed on other machines. security threats

Flash drives present an important security challenge for large organizations. Due to their small size and ease of use, it is possible with the collection of confidential data and smuggling, without the risk of being caught by a free visitor or employee. Both companies and public computers are caught in the danger of the flash drive being installed by an attacker in a free USB port that can use dangerous software like keyboard loggers or packet sniffer.

In case of a computer set up to be booted from a USB drive, it is possible for a computer to access files of a computer, even if the computer password is protected, then a flashable device with a bootable portable operating system can be used. . Password can be changed later; Or it is also possible to break the password and complete control over a computer by a password cracking program. Encryption files provide adequate protection against this kind of attack.

The use of a USB flash drive can be done intentionally or unknowingly to transfer malware and autorunct worms to a network.

Some organizations forbid the use of flash drives, and some computers are configured to disable any other user from accessing a USB mass storage device other than administrators; Others use third-party software to control USB usage. Using the software not only gives the administrator a USB lock, but also allows the use of CD-RW, SD card and other memory devices to be controlled. This enables companies to implement these policies where the use of USB flash drives is against policies. In a low-tech security solution, some organizations cut the USB port in the computer or fill the USB socket with the epoxy. security breach

Examples of security breaches resulting from the use of a USB drive include: Naming

By August 2008, "USB flash drive" has emerged as a common word for these devices, and most large manufacturers use similar words on their packaging, even though potentially deceptive options (such as memory Stick or USB storage) still exist.

Numerous brand names and terminology used in the past and present, makes the research of USB flash drive more difficult for manufacturers and research for consumers. Some commonly used names actually represent trademarks of particular companies, such as Cruzer, TravelDrive, ThumbDrive, and Disgo. Current and future developments

Semiconductor corporations have worked on reducing the cost of components in a flash drive by integrating various functions of flash drives in one chip, thereby reducing the count of parts and the overall package cost.

The flash drive capabilities in the market constantly increase. By 2008, some manufacturers have continued to produce 256 MB and smaller models and many have started to finish the 512 MB capacity flash memory. High speed standard has become standard for modern flash drives, and as of 2009, the market has reached 256 GB capacity.

Lexar is attempting to present a USB flashcard, which will be a compact USB flash drive that replaces the different types of flash memory cards. Pretech introduced a similar card, which takes every USB port, but it is just one quarter of the Lexar model's thickness. SanDisk's product is SD Plus, which is a Secure Digital Card with a USB connector.

SanDisk has introduced a new technology that allows the use of controlled storage and copyrighted material on the flash drive, primarily for students' use. This technology was called FlashCP. Flash drives for non-USB interfaces : Solid-state drive

Most flash drives use USB, but some flash drives use other interfaces such as IEEE 1394, a theoretical advantage of their (FireWire) USB minimum latency and CPU utilization provided by IEEE 1394 protocol , But in practice, all IEEE 1394-based flash drives manufactured due to the spread of USB interfaces use older slow flash memory chips, and any manufacturer, such as 2 009, IEEE sells 1394 flash drives with modern fast flash memory and currently only 4GB, 8GB or 16GB, depending on the model manufacturer available. FireWire flash drives, which need to be connected to the FireWire 400 port, can not be combined with or without a firewire 800 port.

In the second half of 2008, the flash drive using the eSATA interface became available. Compared to the USB flash drive, an advantage that claims to be an eSATA flash drive is enhanced data throughput, which increases the speed of data read and write. However, there is some disadvantage in the use of eSATA for flash drives. The eSATA connector was designed primarily for use with the external hard disk drive, which often included its own separate power supply. Therefore, unlike USB, an eSATA connector does not provide energy other than necessary, usable electricity for signals and data transfer purposes. This means that an eSATA flash drive will still need an available USB port or some other external source of power. Additionally, as of September 2009, eSATA is still a fairly unusual interface on most home computers, so very few systems can currently use enhanced display offers through eSATA interface on such equipped flash drive devices. Finally, with the exception of the laptop computer equipped with eSATA, most home computers that include one or more eSATA connectors, usually look for the port on the back of the computer case, thus in certain situations access to access Makes it harder, and makes installing and deleting flash drives too complex.
