Poor Velociraptor Performance

Just build a new rig with i7 920, P6T Deluxe and some OCZ Platinum.

I am having issues with performance with my Velociraptor 300GB WD3000HLFS.

Here is a screenshot with HDTune.



And here is the info on it. If that helps at all.



In the BIOS it is running in IDE mode. When I tried to use AHCI, Vista x64 wouldn't boot up. It would give a BSOD during the loading screen and reboot. I'm not too familiar with this either... but does it have something to do with that? Am I just stupid and running it slower than it should be. I don't have experience with RAID's at all, and I only have this one drive and an external data drive.

Anyone have any idea what could be causing this?


Update: Got it running in AHCI now, running in UDMA 6/133, still no real performance difference. Forgot to install the drivers. It's late lol.

What's wrong with that? That looks about right for a single velociraptor.

^^agreed, those numbers are very typical of a velociraptor.

Yeah, those numbers are respectable. Notice the 8.6ms access time instead of 12-14ms.

Come to think of it, shouldn't that be in the ~7ms range?

Yes, my Raptor 74G is at 8.1ms so 8.6ms is bad IMO. Probably not the drive, but something isn't quite right. Check the HDtune site for a possible controller configuration cause.

Yea, that was my only concern is the slow access time. I'll have to look up some 0more stuff on it.

Also... the slow burst rates are way down from what I've seen elsewhere... anyone have any clues?

I'm using ACHI and the Intel ICH10R with the newest drivers.

Here are some updated benchmarks, with HDTune Pro Trial.

Doesn't look bad at all to me. Here's my pair of RAID 0 velociraptors on that same test:
