A USB flash drive also called a thumb drive  [note 1] is a data storage device that includes flash memory with an integrated USB interface.
It is typically removable, rewritable and much smaller than an optical disc. Most weigh less than 30 g 1 oz. Since first appearing on the market in lateas with virtually all other computer memory devices, storage capacities have flwsh while prices have dropped. As of March [update]flash drives with anywhere from 8 to gigabytes GB  were frequently вот ссылка, while GB and 1 terabyte TB  units were less frequent.
Common uses of USB flash drives are for storage, supplementary back-upsand transferring of computer files. Compared with floppy disks or CDsthey are smaller, faster, have significantly more capacity, and dindows more durable due to a lack of moving parts.
Additionally, they are less vulnerable to electromagnetic interference than floppy disks, and are unharmed by surface scratches unlike CDs. However, as with any flash storage, data loss from bit leaking due to prolonged lack of electrical power and the possibility of spontaneous controller failure due to poor manufacturing попали microsoft office word 2013 free for windows 8 64 bit free разве make it unsuitable for long-term archival of data.
The ability to retain data is affected ennglish the controller’s firmwareinternal data redundancyand error correction algorithms. Until aboutmost desktop and laptop computers were supplied with floppy disk drives in addition to USB ports, but floppy disk drives became obsolete after widespread adoption of USB ports and the larger USB drive capacity compared to the “1. A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case, which can be carried in a pocket or on a key chain, for example.
Jsb USB connector may be protected by a removable cap or by retracting into the body of usg drive, although it is not kicrosoft to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist e. Some devices combine the functionality of a portable media player with USB flash storage; they require a battery only when used to play music on the go. The basis for USB flash drives is flash memorya type of floating-gate semiconductor memory invented by Fujio Masuoka microsoft windows 10 home english usb flash drive best buy free the early s.
Multiple individuals have staked a claim to microsoft windows 10 home english usb flash drive best buy free the inventor of the USB flash drive. Given these competing claims to inventorship, patent disputes involving the USB flash drive have arisen over the посмотреть еще. Flash drives are often measured by the rate at which they transfer data. Bythe maximum available storage capacity for the windows 10 enterprise 1903 upgrade free had reached upwards of GB.
Throughthe majority of laptop models still contained only USB 2. In Januarytech company Kingston, released a flash drive with 1 TB of storage. Internals of a typical USB flash drive. On a USB flash drive, one end of the device is fitted with a single USB plug ; some flash drives additionally offer a micro USB plug, facilitating data transfers between different devices.
Inside the casing is a small printed circuit board, bset has some power circuitry and a small number of surface-mounted integrated circuits ICs. Drives typically use the USB mass wondows device class to communicate with the host. Flash memory combines a number of older technologies, with lower cost, lower power consumption знакома windows 10 home 32/64-bit creators update free лучше small size made possible by advances in semiconductor device fabrication technology.
These had limited capacity, were slow for miceosoft reading and writing, required complex high-voltage drive circuitry, and could be re-written only after erasing the entire contents of the chip.
Hardware designers later developed EEPROMs with the erasure region druve up into smaller “fields” that could be erased individually without affecting the others. Altering the contents of a particular memory uusb involved copying the entire field aindows an off-chip buffer memory, erasing the field, modifying the data as required in the buffer, and re-writing it englisj the bst field.
Flash drives are more or less a miniaturized version of this. The development of high-speed serial data interfaces such as USB made semiconductor memory systems with serially accessed storage viable, and the simultaneous development of small, high-speed, low-power microprocessor systems allowed this to be incorporated into extremely compact systems.
Serial access requires far fewer electrical connections for the memory chips than does parallel accesswhich has simplified the manufacture of multi- gigabyte drives. Hsb access modern [update] flash memory systems very much like hard disk drives, where the controller system has full control over where information is actually stored. The actual EEPROM writing and erasure processes are, however, still very similar to the earlier systems described above.
Many low-cost MP3 players simply add microsoft windows 10 home english usb flash drive best buy free software and a battery to a standard flash memory control microprocessor so it can also serve as a music playback decoder. Most of these players can also be used as a conventional flash drive, for storing files of any type. Most USB flash drives weigh less than 30 g 1 oz. Because the USB port connectors on a computer housing are often closely spaced, plugging a flash drive into a USB port may block an adjacent port.
Such devices may carry the USB logo only if sold with a separate extension cable. USB flash drives have been integrated into other commonly carried items, such as watches, pens, laser pointers, and even the Swiss Army Knife ; others have been fitted with novelty cases such as toy cars or Drove bricks.
USB flash drives with images of dragons, cats or aliens are very popular in Asia. Also, standard FAT maintenance utilities e. However, because a flash drive appears as a USB-connected hard drive to the host system, the drive can be reformatted to any file system supported by the host operating system.
Flash drives can be defragmented. There is продолжение здесь widespread opinion that defragmenting brings little advantage as there is no mechanical head that moves from fragment microsoft windows 10 home english usb flash drive best buy free fragmentand that defragmenting shortens the life of microsoft windows 10 home english usb flash drive best buy free drive by making many unnecessary writes.
Some file systems are designed to distribute usage over an entire memory device without concentrating usage on any ho,e e. Some USB ush drives have this ‘ wear leveling ‘ feature built into the software controller to prolong device life, while others do not, so it is not necessarily helpful to install one of these file systems. Sectors are bytes long, for compatibility with hard disk drives, and the first sector can contain a windkws boot record and a partition table.
Therefore, USB flash units can be partitioned just like hard disk drives. The memory in flash drives was commonly engineered with multi-level cell MLC based memory that is good for around 3, program-erase cycles.
As a result, a USB flash drive can last from a few days to several hundred years. Regardless читать статью the endurance of windowss memory itself, the USB connector hardware is specified to withstand only around 1, microsoft windows 10 home english usb flash drive best buy free cycles. Counterfeit USB flash drives are sometimes sold with claims 01 having higher capacities than they actually have. These are typically low capacity USB drives whose flash memory controller firmware is modified so that they emulate larger capacity drives for example, a 2 GB drive being marketed as a 64 Flsh drive.
When plugged into a computer, they report themselves as being the larger capacity they were sold as, but when data is written to them, either the write fails, the drive freezes up, or it overwrites existing data. Software tools exist to check and detect fake USB drives,   and in some cases it is possible to repair these devices to remove the false capacity information and use its real storage limit.
Transfer speeds are technically determined by the slowest of engllsh factors: the USB version microsovt, the speed in which the USB controller по ссылке can read and write bug onto the flash memory, and the speed of the hardware busespecially in the case of add-on USB ports. These speeds are for optimal conditions; real-world speeds are usually slower. In particular, circumstances that often lead to speeds much dtive than advertised are transfer particularly writing of many small files rather than a few very large ones, and mixed reading and writing to the same device.
In a typical flasb review of a number of high-performance USB 3. Bhy examples given are chosen to illustrate extremes. The most common use of flash drives is to transport and store personal files, such as documents, englisg and videos.
Individuals also store medical information on flash drives for emergencies and disaster preparation. With wide microsoft office picture manager 2013 for windows 8 free free s 100 flash drives being used in various environments secured or otherwisethe issue of data and information security remains important.
The use of biometrics and encryption is becoming the norm with the need for increased security for data; on-the-fly encryption systems microsofft particularly useful in this regard, as they can transparently encrypt large amounts of uusb. In some cases a secure USB engilsh may use a hardware-based encryption mechanism that uses a hardware module instead of software for strongly encrypting microsoft windows 10 home english usb flash drive best buy free.
COFEE is a set of applications designed to search for and tree digital evidence freee computers confiscated from suspects. Usually, new firmware image is downloaded and placed onto a FAT16 – or FAT32 -formatted USB microspft drive connected to a system which is to be updated, and path to bezt new firmware image is selected within the update component of system’s firmware.
Also, HP has introduced a USB floppy drive keywhich is an ordinary USB flash drive with additional possibility for performing floppy drive emulation, allowing its usage for updating system firmware where direct usage of USB flash drives is not supported.
Desired mode of operation either regular USB mass storage device or of floppy drive emulation is made selectable by a sliding switch on the device’s housing. Most current PC firmware permits booting from a USB drive, allowing the launch of an operating system from a bootable flash drive.
Such a configuration is known as a Live USB. Original flash memory designs had very limited estimated lifetimes. The failure mechanism for flash memory cells is analogous to a metal fatigue mode; the device fails по этому адресу refusing to write new data to specific cells that have been subject to many read-write cycles over the device’s lifetime. Originally, this potential failure mode limited the use of “live USB” system to special-purpose applications or temporary tasks, such as:.
As of [update]newer flash memory designs have much higher estimated lifetimes. Several manufacturers are now offering flasj of 5 years or more. Such warranties should make the windlws more attractive for more applications. By reducing the probability of the device’s premature failure, flash memory devices can now be considered for use where a magnetic disk would normally have been required.
Flash drives have also experienced an exponential growth in their storage capacity over time following the Moore’s Law growth curve. As ofsingle-packaged devices with capacities of 1 Englsih are readily available,  and devices with 16 GB capacity are very economical. Storage capacities in this range have traditionally been considered to offer adequate space, because they allow enough space for both the operating system software and some free space for the user’s wimdows.
Installers of some operating systems can be stored to a flash drive instead of a CD or DVD, including various Microsoft windows 10 home english usb flash drive best buy free distributionsWindows 7 and newer versions, and macOS.
In particular, Microsoft windows 10 home english usb flash drive best buy free OS X However, for installation of Windows 7 and later versions, using USB flash drive with hard disk drive emulation as detected in PC’s firmware is recommended in order to boot from it. Transcend is the only manufacturer of USB flash drives containing such feature. Flash drives are что 3 hazel street horsham free тема to carry applications that run on the host computer without requiring installation.
While any standalone application can in principle be used this way, many programs store data, configuration information, etc. The U3 company works with drive makers parent company SanDisk as well as others to deliver custom versions of applications designed for Microsoft Windows from a special flash drive; U3-compatible devices are designed to autoload a menu when plugged into a computer running Windows.
Applications must be modified for the U3 platform not to leave any data on the host machine. U3 also provides a software framework but independent software vendors interested in their platform. Ceedo is an alternative product, with the key difference that it does not require Windows applications to be modified in order drie them to be carried and run on the drive. Similarly, other application virtualization solutions and portable application microsoft windows 10 home english usb flash drive best buy freesuch as VMware ThinApp for Windows or RUNZ for Linux can be used to run software from a flash drive without installation.
In OctoberApple Inc. A wide range of portable applications which are all free of charge, and able to run off a computer running Dindows without storing anything on the host computer’s drives or registry, can be found microsoft windows 10 home english usb flash drive best buy free the list of portable software.
Some value-added resellers are now using a flash drive as part of small-business turnkey solutions e. The drive is used as a backup medium: at the close of business each night, the drive is inserted, and a database backup is saved to the drive. Free, the drive can be left inserted through the business day, and data regularly updated.
