I have been using a 4Gig Usb flash drive on my XP desktop & thought about buying a 16 Gig one around £29 with a speed of aound 4.5 mbsec. But in Currys they have a £44 one with a speed of around 18.5 Mb.persec.Currys do not know if it would work on mu USB XP pc,any comments.
Be careful about specifications. The read and write speeds are different. When comparing speeds you need both figures. Unscrupulous suppliers may mention the higher value and omit the lower one.
4.5MB/sec would be classed as slow. You can get these from around £13. If you want faster drives you pay more. 7dayshop.com, Play.com and Scan.co uk are good sources for cheap USB flash drives.
USB3 devices are becoming available. They are backward compatible with USB2. USB2 has a practical data transfer limit of around 30-36 MB/sec (theoretical maximum is 60MB/sec). I have seen USB3 devices rated at 240 (read) and 184(write) MB/sec.
My 4GB usb2 drive is set to NTFS. So according to this I could buy a 16GB which should run on my XP Desktop. But would I be able to buy a 16GB ultra fast drive or would it still run at the same speed as my existing 4Gb drive or would it work on a faster speed or what,in other words would I be wasting my money.
