I don't know if anyone here would be interested in these, but I figure it's worth a shot. Just upgraded all the drives in my RAID array to 2tb, so I've got a bunch of 1.5TB sitting around. Here's what I've got:
1x Seagate Barracuda 7200.11; 7200RPM, can't find cache listed on label. P/N is: 9JU138-568
1x WD15EARS 64MB cache
2x WD15EADS 32MB cache
1x Seagate Barracuda Green P/N 9VT15L-570
1x WD15EARS: drive looks different than the other one, but same model number so I'm guessing 64MB cache also (can't see it anywhere on label)
I've also got one or two spare 2TB that I would consider parting with for the right price. I think a 200GB Maxtor and 250GB WD as well.
I'd be looking for about $70 apiece for the 1.5TB drives, non-inclusive of shipping or PP fees. Quantity discounts available. I've probably got some spare SATA to USB adapters if there's interest in those as well.
