RAID Question, what to look for for my performance problem??

Hey all-
I built a new machine over the weekend, and it's supposed to be a screamer, but I'm having a few issues with it. Here is the overall layout.

ASUS CUV4X-D
2x PIII-700@933 retail
256mb Registered ECC RAM (PC133)
GeForce256 DDR
SBLive
Pioneer Slot DVD
Floppy, etc.

AMI Express 200 (Series 466) U2W RAID Card w/16mb cache and i960 chip
3x Fuji 10k 18.2GB Drives, configured as RAID5 on the card.
LVD Cable, 80pin 3 drive backplane.

Everything works great. I had some memory bandwidth issues, but I have got the memory up a bit. It's about 360MB/s now, it was like 230-240 default <--damn low.

On Sandra I'm getting a score of 9661 on the drive benchmark, which is extrememly low for a setup like this. For instance, it has a ATA U66 7200rpm drive getting 17000.

The drives do, although, seem very responsive, and things load quickly. Is this possibly just an error in Sandra, or is something wrong?

Don't trust the benchmarks...

Whenever i test anything i use recorded scripts, these scripts are recorded from regular use, that is the only way to test something (even the so called non synthetic benchmarks sucks, how often do you open, save and close the same documents one hundred times in a row?)...

If the system feels fast then that is because the system is fast... trust your instincts, not benchmarks...

I have a 3xSeagate 18XL RAID0 array that only gets 26,000 in Sandra. But in Winbench 99 it sustains 70MB/sec read/write. Sandra is a very poor benchmark.
