“The DataTraveler's tiny metal frame and prominent key ring make it easily portable,” our tester said of this flash drive. He added, “Downloading files off the drive itself is fast and easy, at over 100 MB/s, and it's also one of the cheapest USB 3.0 flash drives you can get.” The downside? “While read speeds were fine, the DataTraveler struggles to actually copy files onto the drive,” our reviewer explained. “Despite supporting USB 3.0, it barely tops write speeds of 10 MB/s, and lacks any other features.” The takeaway: “We'd only recommend this product as a cheap way for business professionals to pass out digital content to clients, or for networking,” he stated.
Flash drives are often measured by the rate at which they transfer data. Transfer rates may be given in megabytes per second (MB/s), megabits per second (Mbit/s), or in optical drive multipliers such as "180X" (180 times 150 KiB/s).[19] File transfer rates vary considerably among devices. Second generation flash drives have claimed to read at up to 30 MB/s and write at about half that rate, which was about 20 times faster than the theoretical transfer rate achievable by the previous model, USB 1.1, which is limited to 12 Mbit/s (1.5 MB/s) with accounted overhead.[20] The effective transfer rate of a device is significantly affected by the data access pattern.[21]
To ensure this information isn't stolen as well, having a locked flash drive can keep anyone from viewing your files should the drive fall into the wrong hands. Tiny and portable, they easily slip into a pants or coat pocket, in a computer bag or purse, and come in a variety of shapes and sizes. External keypads add an additional level of security to portable memory, meaning a viewer must first input a numerical code to gain access to files. These in turn can be encrypted and password protected, deterring serious threats to personal security.
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.
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.
In the arcade game In the Groove and more commonly In The Groove 2, flash drives are used to transfer high scores, screenshots, dance edits, and combos throughout sessions. As of software revision 21 (R21), players can also store custom songs and play them on any machine on which this feature is enabled. While use of flash drives is common, the drive must be Linux compatible.
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 for independent software vendors interested in their platform.
It's never been easier to take all the files, data or media you want with you wherever you go. Generally about the size of a stick of gum, a USB flash drive lets you store any file from your computer so you can save it, transport it, and load it onto another computer in seconds. You simply plug the flash drive into your USB port and drag any files you want onto its icon on your desktop. Best of all, flash drives have no internal moving parts, so they're very resistant to breaking by being bumped or dropped.
