4 X Raptors in stripe + low HD Tach score, why?

Result with four in RAID 0:

Two of them in RAID 0 earlier today:

Straight into my motherboard mate. As per sig.

ChrisD. · 2 Nov 2007 at 22:25

Optimal mate. Wouldn't have thought the choice of that would bring the score down so much?

Right I managed to knacker one of the SATA ports on one of the drives so I'm down to three, but it's still wrong. I'm not sure why, latest drivers, write cache disabled etc. When I install either Vista or XP, even without any drives plugged in, somethings not right. Not sure what but something isn't...

The drivers installed are the ones for the mobo which I downloaded from EVGA.

Well I got myself O&O defrag and the drives are in a pretty bad state of fragmentation. Should be finished soon.

I also used lifeguard tools and no errors found. As for write cache, I'm not going to disable it as it's good for Windows, plus it shouldn't hinder my score that much.

I'm not really interested in redundancy as it's only the OS and games that go on the drive. Everything important will be backed up onto another drive.

Anyway, I'm still getting poor rates, even slower now then the ones in the screenshot.

Bit off topic here mate but you have 4 Raptors, I have one and is making some serious grinding noises what is it like with 4?

Fine mate, my Barracuda is louder when seeking :eek:

Anyway, fresh install of XP, latest drivers and here's the result. Now with 3 drives remember.

ChrisD. · 6 Nov 2007 at 16:52

Yes they are both off mate.

Found something out....

Right guys, would I see better RAID performance on a Gigabyte GA-P35-DS4?

ChrisD. · 10 Nov 2007 at 22:14

Now on a GA-P35-DS4 and the same woes:

Could it be that one of the drives is a different model number and firmware? I know they are all 8MB cache and 36GB...

ChrisD. · 10 Nov 2007 at 23:07

That's what I'm after! What model numbers/firmware are the drives?

ChrisD. · 10 Nov 2007 at 23:21

Happy now...

Enabled write-back cache and bang it's running much better.

Now just got to wait for WD to send my replacement.

I think that's down to the Intel controller mate. I thought that might have been a glitch, but here's a couple of screenshots showing settings and a HD tune benchmark.

Don't ask me why my burst speed is so ridiculously high!
