Most of the 250GB PATA drives ended up in the $0.46 per GB range this week, although a few of the slower 5400RPM drives managed to hover around $0.39. We actually noticed the Seagate 250GB Barracuda 7200.8 [RTPE: ST3250823A] picked up a huge rebate since our last guide, but the drive is still going to cost you $0.46 out the door; at which point you're much better off grabbing the NCQ-enabled SATA 7200.8 instead.
The largest drops this week were in the 400GB to 500GB range. We saw $4 to $10 drops on average, but the cost per GB is still above $0.55. These drives do not warrant a purchase unless you absolutely need the density. Check out the history of the rapidly moving Hitachi 400GB Deskstar 7K400 below:
Unfortunately there isn't much else to report about PATA drives. Just keep watching the cost per GB drop.
