Here is a great way to backup 'must have' files when you're traveling, or to conveniently swap data between computers.
Do you need a USB Flash Drive
If you're traveling and your laptop becomes lost or broken, what would you do if you had a vital Powerpoint presentation trapped on its hard drive?
Or if you want to conveniently take some files from the office to home, work on them, and then return them? How would you do that?
Traditionally, all computers had floppy disk drives, and their 1.44MB capacity was more than enough to handle any reasonable type of file you'd ever need to transfer. These days, many new computers don't have any floppy drive at all.
As programs and files became larger, CDroms - a technology that almost died as a non-mainstream curiosity and which Bill Gates championed - became more common and now are almost universal. CDrom writers also became more common, and transferring larger files was commonly done by burning them to a CDrom.
Various other technologies, such as Iomega's Zip (100-250MB) and Jaz (1-2GB) drives, also briefly appeared and then disappeared again.
Flash forward to the present day. Few computers even have a floppy disk drive. While most computers have CDroms, not all have CD burners, and even though the cost of single use CDs has dropped down to less than 50c each, the technology to write onto them is cumbersome and slow. A newer technology - DVDrom - is appearing; happily DVDrom drives usually read CDroms too.
A new type of universal data storage format was/is needed. Increasingly it seems that the USB flash drive might be exactly what is now needed
