I needed a drive for all my work on the go, also something that would have all my photos, videos and music on. I got this from PC World about a year ago for just under £50, at the time their were cheaper drives and drives with more capacity, but non at this size.
Speed wise, its not the fastest drive around but that is because its a USB drive, but you can get about 20mb/s out of it which is not too bad, if your going to copy large amounts to it, you'll have to leave it running in the background.
Looks wise, this looks very stylish, although it feels very cheap, I have dropped this a few times and with no apparent damage, physically or to the data. I have taken the blue cover off completely as well once, when the hard drive failed to be recognized by my PC, just to see if it was the drive itself or not and it uses an Hitachi 2.5 incher which runs at 5400rpm. The problem turned out to be the cable that came with the drive, which is about a foot long and tends to come out if the drive is moved even slightly. I now have a cable meant for a blackberry that works quite well, but occasionally the drive is not recognized by that and i need to connect it with the original cable to get it to work.
You do not need an instruction manual for this drive and although it came with one, i do not remember ever reading it, all you need to do is plug the drive into a USB slot on your PC and away you go. The drive does come with some software, which gives it some extra features such as synchronizing your files across different computers and updating the firmware on the hard drive. I found the software to be intrusive and useless so never used it apart from updating the drive when i first got it.
Every time you plug the hard drive in, it will try loading the software, but you can turn this off. This would be OK for a person who is not very computer savvy, but for everyone else, you would rather do everything yourself, manually. Due to this you also lose about a gig to the drive software, but at this size it doesn't really matter.
Overall, I would recommend this, as you get quite a lot of capacity, it comes in a small box that can fit in your pocket, and the drive is relatively quick for a USB2 drive. You would need a replacement cable but these only cost a few quid anyway.
I've owned this hard drive for around a year and it has been flawless.
Its a tiny drive (western digital's smallest portable drive ever according to their website!) it doesn't come with a case but i bought a caselogic one on amazon for about £6 which fits perfectly.
Drives are unpredictable and do die easily compared to other electronics - thats why you find so many mixed reviews for each drive. Another drive i had died when dropped but so far this ones been a dream! Just plug in and go. Very small and lightweight and no failures!
I always back up twice on two different drives to minimize any risk of failure.
The drive is very attractive looking and the plastic body has a quality feel. The drives pretty quiet when in use and i would say its about an average transfer speed.
Overall i would definitely recommend this drive but also suggest purchasing a case as well for an extra level of protection. It is a portable drive but i don't think it would survive much of a bashing!
