Re: Help choosing HD
1 TB WD Black's are comparable to the Raptors in many benchmarks. When you look at game related benches you only see the Raptor ahead with load times by a second or two at most, and that's with a 30 second load versus 32. Not even noticeable.
You could always go the bat-****-crazy route and buy two Enterprise level drives at 15k RPM, a bitchin controller, and RAID 1 the drives.
Or just buy the SSDs.
I'd recommend going with any 1 TB drive that you like. I'm partial to Samsung and WD.
