I'm seriously considering getting the 74gb Raptor as a primary boot drive, than using a 320 WD Caviar drive for all my other stuff. The price is huge considering the amount of storage, but it looks like a speedy lil drive. Nice looking too. But is it worth it or would it be better money spent going after another 320 gig drive? Will it significantly increase boot and access times? Is it a highly reliable drive?
