Help - Raid 0 & Vista 19ms random seek

Hey Guys,

Been looking around for ages to try and fix this error.

My system specs are this.

E6600
2gb DDR2 A-Data 800
2 Seagate 250gb drives in Raid-0 Intel controller
Vista Business Edition.
Gigabyte 965-DS3P
8800gtx

I didnt have to press f6 when installing, it picked up the drives fine, however now under device manager it is showing as no drivers being installed for the raid?

I have the Intel matrix storage manager installed.

And have just run HDTach which gave me a random seek speed of 19m/s

This seems incredibly slow to me, especially for raid 0

The over time speed was 6ms

Can anyone, or does anyone know of what I can do to try and fix this or if it is normal?

Thanks
Marc

Raid 0 will actually have worse seek times if anything

I'm more of a Linux guy than Windows so I'm not much help here, I don't know much about Vista other than it's buggy and slower than XP, it sounds like the drivers are to blame but I could be completely wrong. Also check to see if the drivers are in "silent" mode, that will make the seek times much worse.

I agree with JT001. RAID 0 has significantly increased sustained transfer speeds, but can (not always) be slower for access times. I'd say you're seeing normal behavior.

the slower access times are to be expected for software based onboard raid 0 (best case scenario for raid 0 is that youll get within 1ms slower than a single hdd would)... vista IS slower than xp, it tends to use up more cpu cycles, even when idle, which would result in poorer raid performance in general anyhow... you could have also had additional activities and unnecessary processes running during the testing too, which would give worse performance than if absolutely nothing else was going on

all in all though, i would say your results are within normal range (some 7200s are about that slow for random access times anyhow, and having those particular hdds in raid 0, certainly wont do anything to improve their times)

edit: the only way youre going to get noticably improved access times, is by using a hdd with higher rpms (10k and 15k), or by going with a solid state disk, which has sub 1ms access times, i believe... other than that though, again, your current access times appear fairly normal

Welcome to Vista...please drive thru.

The only way I would install Vista on my systems is if they paid me...and as soon as the check cleared I would reformat and reinstall XP. :!:
