The various writable and re-writable forms of CD and DVD are portable storage media supported by the vast majority of computers as of 2008. CD-R, DVD-R, and DVD+R can be written to only once, RW varieties up to about 1,000 erase/write cycles, while modern NAND-based flash drives often last for 500,000 or more erase/write cycles. DVD-RAM discs are the most suitable optical discs for data storage involving much rewriting.
USB flash drives have been integrated into other commonly carried items, such as watches, pens, and even the Swiss Army Knife; others have been fitted with novelty cases such as toy cars or Lego bricks. USB flash drives with images of dragons, cats or aliens are very popular in Asia.[36] The small size, robustness and cheapness of USB flash drives make them an increasingly popular peripheral for case modding.
Also, HP has introduced a USB floppy drive key, which is an ordinary USB flash drive with additional possilibility 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.[51][52]
Motherboard firmware (including BIOS and UEFI) can be updated using USB flash drives. Usually, new firmware image is downloaded and placed onto a FAT16- or FAT32-formatted USB flash drive connected to a system which is to be updated, and path to the new firmware image is selected within the update component of system's firmware.[49] Some motherboard manufacturers are also allowing such updates to be performed without the need for entering system's firmware update component, making it possible to easily recover systems with corrupted firmware.[50]
Not everyone wants every file they've ever created available in the cloud. It can put data at risk - not just from hackers or spammers or nosey bosses, but with some providers offering shady terms, you could lose the intellectual rights to anything uploaded. Having a portable memory drive means you don't have to sacrifice mobility for security, though, making flash drives an ideal solution for business people on the go.
The 32GB capacity of this SanDisk Ultra SDCZ48-032G-A46 flash drive provides ample room to store photos, music, videos and other files. The USB 3.0 interface and up to 80MB/sec. read speed make it easy to transfer files to and from your computer. (Ten times faster than USB 2.0 drives. Write speeds up to 10 times faster than Cruzer USB 2.0 drive.)* *USB 3.0 port required. Based on internal testing; performance may be lower depending upon host device.
Artists have sold or given away USB flash drives, with the first instance believed to be in 2004 when the German punk band Wizo released the Stick EP, only as a USB drive. In addition to five high-bitrate MP3s, it also included a video, pictures, lyrics, and guitar tablature.[58] Subsequently, artists including Nine Inch Nails and Kylie Minogue[59] have released music and promotional material on USB flash drives. The first USB album to be released in the UK was Kiss Does... Rave, a compilation album released by the Kiss Network in April 2007.[60]
There are 2 ways; which one depends on how many USB ports you have. If you have 2, then put both flash drives in, open up in the file browser and move the information between the two drives in the file browser. If there is only one socket, put the first flash drive in and place the files to be transferred on the computer, then unlpug and put the next drive in. If you have no USB ports, you will need an adapter (Mac). You could also transfer files to the Cloud, then download them onto the other flash drive.
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.[48] Forensic software is required not to alter, in any way, the information stored on the computer being examined. Other forensic suites run from CD-ROM or DVD-ROM, but cannot store data on the media they are run from (although they can write to other attached devices, such as external drives or memory sticks).
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 block-structured 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 up from flash drives.
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 disk-based backup is now the primary medium of choice for most companies, tape backup is still popular for taking data off-site for worst-case scenarios and for very large volumes (more than a few hundreds of TB). See LTO tapes.
Many types of USB drive, sometimes referred to as a thumb drive, also have handy features like a key chain ring or a small LED flashlight. Some can even transmit your data wirelessly for the ultimate in digital convenience. And as with any fun accessory, there are plenty of novelty versions of flash drives designed to show your personality, display your sense of humor, or broadcast your team loyalty.
