hi, i'm looking for either a single or Raid 0 configuration but thing is I've NEVER broken the 100 Gig wall (in other words I don't need any more than let's say 200 Gigs), even with all the useless crap possible, in normal time I'd just take the first thing I see but I really want a relativly quick hard drive and someone told me that different versions run at different speeds and I should investigate, over than the 7'200 RPM and 10'00 RPM I haven't found anything, what do you suggest?
If you've never gone beyond 100GB (I've filled that up and then some...) you don't need a 500GB drive. I'd just grab a nice 7200.10/7200.11 Seagate simply for the nice 5 yr warranty. A 250GB 7200.10 should be around $60.
Unless you are doing something that requires massive harddrive speed, I wouldn't worry about it. 8MB vs 16MB, as long as its a current model 7200RPM drive, I doubt you'd see much difference in performance.
