If you want a truly portable data storage device, look no further.

Applied Technology Systems, of Hampstead Road, Brighton, has developed the FlashDio range of miniature solid drives which can hold up to 1Gb of digital data in a neat case smaller than your thumb.

It plugs into a USB port and there is no software to install. This device really is plug-and-play.

The unit is powered from your computer's port so there are no batteries to replace.

It looks just like another conventional drive on My Computer and files can be accessed as if they were on your computer's hard disc.

The best gadgets are so simple you wonder why you haven't picked up one before.

This one is exceptional and ideal for anyone transporting secure data or working between two computers.

Price: £33 to £620 (depending on size, from 16Mb to 1Gb).
