i was thinking...
i can get 2 x seagate 7200.1 80gb and RAID them for an OS drive. they are pretty zippy, too. and they cost 40 bucks each (2 cost same as 1 ssd). and they are more than twice as big.
hmmmm....
the samsung 320GB's i got were only $50 bucks i think, and they use 333GB platters so they're right up there with the best of the 7,200rpm's
