HistoryTechnologyCounterfeit ProductsFile Transfer SpeedsUsesConveniencesComparison with Other Portable StorageControversiesCurrent and Future DevelopmentsThe basis for USB flash drives is flash memory a type of floatinggate semiconductor memory invented by Fujio Masuoka in the early 1980s Flash memory uses floatinggate MOSFET transistors as memory cells Multiple individuals have staked a claim to being the inventor of the USB flash drive On April 5 1999 Amir Ban Dov Moran and Oron Ogdan of MSystems an Israeli company filed a patent application entitled “Architecture for a Universal Serial BusBased PC Flash Disk”The patent was subsequently granted on November 14 2000 and these individuals have often been recognized as the inventors of the USB flash drive Also in 1999 Shimon Shmueli an engineer at IBM submitted an invention disclosure asserting that he had invented the USB flash drive A Singaporean company named Trek 2000 International is the first company known to have sold a USB flash drive and has also maintained that it is the original inventor of the device Finally Pua KheinSeng a Malaysian engineer has a On a USB flash drive one end of the device is fitted with a single USB plug some flash drives additionally offer a micro USBplug facilitating data transfers between different devices Inside the plastic casing is a small printed circuit board which has some power circuitry and a small number of surfacemounted integrated circuits (ICs)[citation needed] Typically one of these ICs provides an interface between the USB connector and the onboard memory while the other is the flash memory Drives typically use the USB mass storage device classto communicate with the host Counterfeit USB flash drives are sometimes sold with claims of 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 GB 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 drivesand 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 three factors the USB version used the speed in which the USB controller device can read and write data onto the flash memory and the speed of the hardware bus especially in the case of addon USB ports USB flash drives usually specify their read and write speeds in megabytes per second (MB/s) read speed is usually faster These speeds are for optimal conditions realworld speeds are usually slower In particular circumstances that often lead to speeds much lower 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 wellconducted review of a number of highperformance USB 30 drives a drive that could read large files at 68 MB/s and write at 46 MB/s could only manage 14 MB/s and 03 MB/s with many small files When combining streaming reads and writes the speed of another drive that could read at Personal data transport The most common use of flash drives is to transport and store personal files such as documents pictures and videos Individuals also store medical information on flash drives for emergencies and disaster preparation Secure storage of data application and software files With wide deployment(s) of flash drives being used in various environments (secured or otherwise) the 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 onthefly encryption systems are particularly useful in this regard as they can transparently encrypt large amounts of data In some cases a secure USB drive may use a hardwarebased encryption mechanism that uses a hardware modu Computer forensics and law enforcement A recent development for the use of a USB Flash Drive as an application carrier is to carry the Computer Online Forensic Evidence Extractor (COFEE) application developed by Microsoft COFEE is a set of applications designed to search for and extract digital evidence on computers confiscated from suspects Forensic software is required not to alter in any way the information stored on the computer being examined Other forensic suites run from CDROM or DVDROM but cannot store data on the Flash drives use little power have no fragile moving parts and for most capacities are small and light Data stored on flash drives is impervious to mechanical shock magnetic fields scratchesand dust These properties make them suitable for transporting data from place to place and keeping the data readily at hand Flash drives also store data densely compared to many removable media In mid2009 256 GB drives became available with the ability to hold many times more data than a DVD (54 DVDs) or even a Bluray(10 BDs) Flash drives implement the USB mass storage device class so that most modern operating systems can read and write to them without installing device drivers The flash drives present a simple blockstructured logical unit to the host operating system hiding the individual complex implementation details of the various underlying flash memory devices The operating system can use any file system or block addressing scheme Some computers can boot upfrom flash driv Tape The applications of current data tape cartridges hardly overlap those of flash drives on tape cost per gigabyte is very low for large volumes but the individual drives and media are expensive Media have a very high capacity and very fast transfer speeds but store data sequentially and are very slow for random access of data While diskbased backup is now the primary medium of choice for most companies tape backup is still popular for taking data offsite for worstcase scenarios and fo Floppy disk Floppy disk drives are rarely fitted to modern computers and are obsolete for normal purposes although internal and external drives can be fitted if required Floppy disks may be the method of choice for transferring data to and from very old computers without USB or booting from floppy disks and so they are sometimes used to change the firmware on for example BIOS chips Devices with removable storage like older Yamahamusic keyboards are also dependent on floppy disks which require comp Optical media The various writable and rewritable forms of CD and DVD are portable storage media supported by the vast majority of computers as of 2008 CDR DVDR and DVD+R can be written to only once RW varieties up to about 1000 erase/write cycles while modern NANDbased flash drives often last for 500000 or more erase/write cycles DVDRAMdiscs are the most suitable optical discs for data storage involving much rewriting Optical storage devices are among the cheapest methods of mass data storag “Flash Drives for Freedom” The New Yorkbased Human Rights Foundation collaborated with Forum 280 and USB Memory Direct to launch the “Flash Drives for Freedom” program The program was created in 2016 to smuggle flash drives with American and South Korean movies and television shows as well as a copy of the Korean Wikipedia into North Koreato spread proWestern sentiment Semiconductor corporations have worked to reduce the cost of the components in a flash drive by integrating various flash drive functions in a single chip thereby reducing the partcount and overall packagecost Flash drive capacities on the market increase continually High speed has become a standard for modern flash drives Capacities exceeding 256 GB were available on the market as early as 2009 Lexar is attempting to introduce a USB FlashCard which would be a compact USB flash drive intended to replace various kinds of flash memory cards Pretec introduced a similar card which also plugs into any USB port but is just one quarter the thickness of the Lexar model Until 2008 SanDisk manufactured a product called SD Plus which was a SecureDigitalcard with a USB connector SanDisk has also introduced a new technology to allow controlled storage and usage of copyrighted materials on flash drives primarily for use by students This technology is termed FlashCP.
