Nvidia Raid Extremely Slow
Hello all,
System specs are as follows:
MOBO: M2N-SLI Deluxe
CPU: AMD Phenom 9500
RAM: 6GB Corsair DDR2 800
DRIVES: 3 WD1001FALS
VIDEO: Geforce 8800 GTS
POWER: PC Power & Cooling 750
OS: Windows XP 64 Bit
The problem I am having:
I am running a raid 5 with the 3 wd drives and am getting terrible performance when reading or writing. When transferring a file speeds will start out at about 120MB/s but then drop to a crawl at 10MB/s after about 30 seconds into the transfer. I am beginning to think that the built in raid controller is the culprit but I was hoping to get some opinions before buying a separate card.
Steps I have taken in attempt to fix the issue:
Updated the BIOS to the latest version.
Reinstalled the OS and installed the latest drivers.
Disabled command queuing which was suggested on a forum I read but had no effect.

Check with the raid controller's utility whether all HD's are still fine. What source/destination are you copying from or to?

1. All drives are shown as having a "Healthy" status in the.
2. It actually doesn't seem to matter on the source / destination of transfers. Obviously the starting transfer rate will vary depending on whether I am doing a read/write to or from a local drive or from a cd / external drive to the raid configuration but all of them then drop way down after about 30 seconds or so of "proper" transfer speeds.

Then it does look as if there is an issue with the controller. But another issue could be that you are using XP64 and it's drivers. Driver support for that OS version never was really good, so it is possibly that you just don't have a good driver. Is it possible for you to test the system using another OS?

Just looking at the prices of a good raid controller makes me cry so I will be trying a different OS and will see what happens. Would the latest build of Ubuntu be a viable OS to test this with?
Sure, although I think the new 9.04 version for 64bit CPU's isn't out yet (you can get a beta version).
