One of the best ways of speeding up a Windows PC is to give it more memory. If you have a Windows Vista PC, its new ReadyBoost feature lets Vista use a USB Key for caching data - providing the USB Key is fast enough. The Transcend 8Gb JetFlash 2A silver has been enhanced to be fast enough for ReadyBoost.
Shortlist
There are over 200 USB Keys available on Amazon.co.uk, and it can be difficult to narrow the choice down. To get into our shortlist, a USB Key has to stand out from the crowd. Excellent 2Gb USB Keys are available for a tenner, and we don't think it worth buying anything smaller - so that eliminates about half of the products on offer.

One feature which very much makes a USB Key stand out is speed - how fast it transfers data. Indeed, our Best Buy, Transcend 8Gb JetFlash 2A silver, is one of the fastest USB Keys available. The Transcend 16Gb JetFlash 2A silver
has the same fast data transfer rates. The Transcend 2Gb JetFlash 2A silver
and Transcend 4Gb JetFlash 2A silver
have slightly slower data transfer rates - up to 16MBytes/second for reads, and up to 12 MBytes/second for writes; these data rates are still very impressive, and much better than most of the USB Keys out there.
The fastest USB Key we've found to date is the Sony 2Gb Micro Vault Excellence - 29 MBytes/second for reads, and 23 MBytes/second for writes. Given the power of the Sony brand, and the renowned Sony build quality, this is a top-class product. It doesn't have AES Encryption, otherwise it would be our Best Buy. Its bigger brother, the Sony 4Gb Micro Vault Excellence
, is slightly slower at 26 MBytes/second reads, 19 MBytes/second writes.
Another stand-out feature is robustness, as USB Keys are often carried around in pockets and handbags, and get taken to and fro to school. For robustness, the Integral 2Gb Splash Yellow Shock & Water Resistant and Integral 4Gb Splash Yellow Shock & Water Resistant
get into our shortlist. They are rather slow, at 12 MBytes/second reads and 3 MBytes/second writes - but if all you want is a highly visible, almost indestructible USB Key for your kids to use, then do consider these. They come in yellow, pink and blue.
The very latest U3 Keys are the Sandisk 2Gb Cruzer Micro U3 Readyboost, Sandisk 4Gb Cruzer Micro U3 Readyboost
, and the faster Sandisk 2Gb Cruzer Titanium U3 Readyboost
and Sandisk 4Gb Cruzer Titanium U3 Readyboost
. These are all good enough to support ReadyBoost.
Note that the SanDisk Cruzer comes with Skype, the free Internet phone system, pre-installed. See our Skype Buying Guide for more details.
