    While many USB flash drives come with encryption software to help protect your data, very few go to the lengths of iStorage.

    LaCie FastKey 120GB review

    LaCie FastKey 120GB review

    It's small enough to take anywhere, but is the LaCie FastKey 120GB worth the money?

    Verbatim Store 'n' Go USB Executive review

    7  

    As the name implies, this memory key isn't aimed at the entry-level market, but business users looking for something a little different from their portable storage.

    Corsair 4GB Voyager Mini review

    Corsair’s Voyager Mini somehow packs 4GB of capacity into this wee portable flash drive, which is no bigger than a man’s fingernail.

    Rally 2 32GB Flash drive review

    9  

    OCZ’s Rally 2 sticks have impressed ever since their first 1GB iteration, and now that the boffins at OCZ have managed to cram a ludicrous 32GB into such a tiny form-factor, we’re smitten.

    Sandisk Cruzer Tag review

    8  

    This Sandisk memory key is small and compact, but comes with an oversized lid, which can be used to clip it to your shirt pocket. With 4GB of space, this is the latest must-have capacity for the price.

    OCZ Mega Kart review

    8  

    We've been using the Mega Kart for some time now, and it's proved a sterling office workhorse, bang-on for piping around game installations, batches of screenshots, and Alan's terrifying internet discoveries.

    OCZ ATV review

    We checked out the wasp-like, turbo-charged version of the ATV flash memory stick a few months back and now we’ve got its big brother, the black and blue, 16GB version.

    You'll either love or hate the design of the ATVs, depending on how much you like the feel of rubber. Rubberized casings are all the rage, in a range of products where differentiation is now the key.

    The more traditional type of memory stick, the PD18 is neat andcompact, with one small innovation that is rather pleasing: it comeswith a rubber bung on the keyring

    Adata PD17 2GB review

    8  

    The latest in a neat line of shrinking storage devices, this little chap from ADATA fits an impressive 2GB of space into its diminutive shell. Hook it up to a lanyard or stick it on your keyring and you'll barely know it's there.

    PNY 4GB Attache Capless Concept review

    Flash storage really is one of those technologies that has crept up on everyone. It's now everywhere and is seemingly unstoppable. These latest 4GB and 8GB capacity thumb drives are appearing at ludicrously low prices

    A-DATA PD17 - 1 GB review

    8  

    As Flash storage continues to get smaller and more affordable, the A-DATA PD17 is one of the most compact and usable devices we've seen. Available in a choice of gold, red or blue, it clips neatly on to a keyring or lanyard and offers up to 4GB of storage

    Transcend Jetflash160 review

    Not quite the fastest drive on test, but above average in the transfer speeds stakes, Transcend's 4GB Jetflash drive offers respectable performance for the reasonable asking price of £30.

    PNY Attache Pro review

    8  

    PNY has been in the game a while, so it's no surprise to learn that the Attache Pro features rippingly fast transfer speeds. At £38, it's not unreasonably priced for a 4GB drive, but the performance is hardly reflected in the device's 'striking' looks.

    Freecom USB Card review

    Freecom USB Card review

    5  

    At £19, the Freecom USB DataCard is far from a serious investment. The design is simple and impressive - it's considerably thinner than OCZ's Mega Kart, meaning you really wouldn't feel the girth bulging out your wallet.

    Corsair Flash Voyager GT review

    9  

    The gimpy rubber sheath around the Corsair Flash Voyager GT's exterior may not be everybody's cup of tea, but there's no denying the power of this little stick. 8GB of the fastest Flash around nets you colossal transfer speeds.

    Corsair Flash Survivor GT review

    8  

    The Survivor is pricey for an 8GB drive. But then, it's packed with fast chips, and housed in aircraft-grade aluminium, for the major selling point of the Flash Survivor GT is its sheer toughness.

    Transcend V90 Pearl review

    9  

    While it takes a long time to write files to the Pearl, reading from it is impressively swift. But that's not the unique thing about the Pearl. It's tiny - and comes with a stylishly simple necklace chain, so you can wear it as a piece of jewellery.

    OCZ Rally review

    8  

    With some of the highest speeds on test, the dual-channel memory of the Rally nets it some healthy speed scores. While it doesn't quite reach the heights of the Corsair sticks, it still offers considerably better-than-average speeds.
