I did some work for someone and part of the deal were 4 15K drives. They looked like sata but are in fact SAS. Seagate Cheetah drives 15K 7. speed 64 M cache 300 gig. They're in a clamshell case and don't seem as if they have ever been installed. I have no way to test these, but I assume they are new. I would like to trade these for: A Crucial 250GB SSD 4 GIGS of Ram and A Western Digital 500 GB velicoraptor 10,000 rpm drive sata I'll send these out first so someone can evaluate them, so there's no risk on your part. Any takers?
