Hey, so my HDD is getting old. I'm replacing it with a large drive. I'd like to get another boot drive, for XP/win7 install, and I can't seem to google up a comparison at all.Another thing I'm desperately curious about - if I build the SSD out of class 6 SD cards, or CFs, or anything like that, would it still contend for speed against a 15000 RPM ...
