Fujitsu HandyDrive

External hard disks provide a simple way to expand your computer's storage, and the HandyDrive lives up to its name. It's small, thin, light enough to slip into a pocket and it can store 100Gb of files.

The device plugs into a USB 2 socket with the supplied cable but it requires a lot of power from the USB port. If you are using an external hub, it will need its own power supply. There is a power socket on the drive, but no adapter supplied, so you'll have to find your own if you need one.

When first attached, the device draws its own drivers from the supplied CD. The disc also contains a manual, which confusingly refers to the drive needing a FireWire connection - this is not the case.

Operation couldn't be simpler, as the HandyDrive appears as a named drive in My Computer, into which files can be dragged and dropped. We copied about a gigabyte of music to the disk in just over a minute, which is impressive. It comes with a carry case with a separate section for the USB cable.

The only disappointment is the price - shop around and you can get three times the storage for this money or the same storage for half the cost.
