Just replaced my 40gb with a 250gb Western Digital 5400 for just £50. Of course the 250gb is really not that much - it`s 232 in the end. I wonder how they get away with it. Good job similar marketing doesn`t apply to petrol sales. Unless I`m missing something.

One weird thing though, before the change I had 14gb/40gb free. After the system back up and restore I had 189gb/232gb. Those numbers don`t seem to make sense, unless the PS3 grabs a % of the HDD for its own use with updates. I heard it does reserve some for its own mysterious uses.

I was a bit scared in the HDD changeover operation, and my pulse rate was definitely above normal! But the disk change is very very very easy to do. You would have to be a neanderthal to mess it up really.
