Space not an issue and I dont want to do raid or go for a WD raptor. WHich one is faster or will they be exactually the same? Just want a speed, performance answer not a price or space one.
Id go for the 1tb just 'cos its 250GB extra. Speed wise they're going to be pretty similar if they're both 7200RPM, decent amount of cashe, SATAII etc. It its purely a storage drive (as say your getting a raptor for OS) then the speed isn't of the upmost anyway, where as capacity is.
I have 2 of the 750GB versions - they're about to be RAID'd in RAID 1. Will get some HTtach benchies up when I have the rig built...then we can do some comparisons.
