What is the difference between these?

[Fireplay5]

I have noticed that there is a Western Digital Raptor 74gb sata 10,000rpm drive and a HP 74gb sata 10,000rpm drive. They both boast the 4.5ms time. So what is the difference between these? Is the HP just a knockoff or is it the same drive just being sold by HP? I found a guy selling the HP's but claiming they are WD. Any ideas? Thanks.

HP 74gb 10,000rpm SATA

WD 74gb 10,000rpm SATA

From what i can tell, its a rebadged WD drive.
Not sure tho, if you really need/want to know id call them.

The HP probably is a rebadged WD drive.
Look around a bit. I have seen them for less than $160.00 with rebates in a few places.

I have one, and its a great drive. Fast and quite.

That is what I was thinking also. I have emailed him a few times without any replies and when I try to call him I get a fax response. Hmm. Maybe not the best person to do business with.
