RAID0 with high CPU usage !!??

HvH · 16 Sep 2008 at 13:11

Hi everyone, first post

Just bought two SEAGATES 320GB 7200.11 HD's....made a RAID0 setup.

Just did a HD TUNE utility test.

Transfer rate AVERAGE 179 ms
Access > 17.5
Burst rate > 85.5
CPU usage > 11.4%

That CPU usage seems a little high ??

Any HD experts out there ?? ..anyone with a RAID0 setup ??

Processor Intel Core 2 DUO E8500 @ 4.0 - EVGA nForce 680i (Socket 775) PCI-Express DDR2 - Crucial 2GB (2x1GB) DDR2 PC2-5300C3 667MHz Tenth Anniversary Dual Channel Kit (4-4-4-12-1T) - Asus TOP 260GTX - Soundblaster X-Fi Xtreme Gamer - ViewSonic VX912 - Enermax 600 Watt - Windows XP Home Edition. and two SEAGATES 320GB 7200.11 in RAID0 setup.
Running at 4.0GHZ and Memory 889MHZ with 4-4-4-10-1T and 1:1 stable !!

It's maybe a hint high but not a lot, looking at the benchmark thread the normal usage for RAID0 tends to be 6-9%.

Is this a new OS install on the array? It may be doing other stuff in the background.

Wow thats fast

Yes, its a clean XP Home install.

And the other score, fine or bad ??

Thanks

Hans.

PS, I also have two older SEAGATES running, 200GB and a 80GB...thats the problem ??

If you get CPU usage with RAID 0, does it affect speedstep any?

Sorry, can you explain a little more...I am not such an experts as you guys

Where to look if it affect speedstep.

Saw SPEEDSTEP is disabled in my BIOS ??

Thanks.

Sorry my question wasnt really connected to the topic, just wondering as seeing how RAID 0 gives you a CPU usage, does it keep a CPU in the fastest state with speedstep enabled.

Can't enable it...there is a little cross in front (BIOS) ...its grey. can't change that setting at all.

But I wonder if those two SEAGATES 200GB and 80GB uses the extra CPU usage in the back ??

Did a clean XP install.

Disconnected those two other SEAGATES 200GB and 80GB

CPU usage 7.8 % now...not bad

This is with the latest 15.24 Nforce driver.
