Fistly I will write that I am expecting this to get voted cold as it is not the cheapest 500gb desktop hard drive on the market as i know you can get buffalo 500gb drives for £10 cheaper at cddiscounts but this is a seagate drive so you know you are getting a good drive and it comes with a 5 year warranty which is always nice, it has a 16mb cache rather than the 8mb that most of these cheaper drives have and it is at least £10 cheaper than amazon, dabs and play.
