The Kingston DataTraveler Mini Slim is, indeed, both mini and slim. Measuring in at just under four centimetres long and just over half a centimetre tall, it still manages to pack in a decent four gigabytes of storage - and it's no slouch performance-wise either.
The drive comes in several colours - namely black, blue and pink, each with a grey underside. The grey/pink combo isn't hugely attractive, but the others look fine. They also look simple, which is kind of the point - these are uncomplicated devices with no pre-installed software or security features, and they come in at a budget price. They're still nice and sturdy, though, and although you probably shouldn't try jumping up and down on them they'll stand up to some pretty rough treatment.
That's a good thing too because the small form factor means that these don't come with a cap for the USB plug, since they essentially only provide the bottom half of a standard USB plug and are merely missing a small amount of housing. But there are no pins to bend and the drive will still work in any standard USB port.
Kingston is a well-known name in the world of computer memory, and it shows. Even though these devices are tiny, simple and cheap, they still outperform my other no-name USB drive, especially on read speeds.
The only real disadvantage is that they may be a little too small; you won't notice if one slips down the side of your sofa. Cheap to buy and simple to use, Mini Slim is ideal for laptop users who want a tiny drive they can take anywhere with them and toss into their laptop bag when they're done with it.
