Hi guys,

first time poster here, ive just decided to upgrade from my standard HDD and i wanted to buy a new one with lots of space but i am not sure which one to get.
money isn't really an option but i want the cheapest i can get and lower than say 80 ONO (im from London so deals from US only websites won't count.
Im looking for a 500GB drive with a good spec (you could advise me on the Cache and RPM. i really don't know where to look or what to look for.

while lurking i found this:WD 500GB SCORPIO BLUE 2.5 INCH 5400RPM 8MB SATA HDD but i'm not sure if it will do the trick so suggestions are welcome.

also i am open to other combinations (e.g 320 if you think its more worth it, i just don't want to be running out of space).

Thanks a lot
