New Raid 5 Very Slow

I just created a new RAID 5 array on my Vista 64 computer using 3x 1 TB Western Digital Caviar Blacks Model# WD1001FALS.

It seems to be much slower than I had hoped, I get random momentary freezes also but then the computer will come back.

Here is a link to my computers specs. The Raid is on the Motherboard. System Specs here

I have attached some HD Tune Screenshots. One image is of 1 Single HD with decent speeds.
The next 3 are screen shots of the Raid 5. You can see there is a very wide range of results. During this time of all 3 I only have open firefox and am not doing any major tasks or strains.

Well, the Caviar drives are also not appropriate for a raid controller, either, as I stated previously. YOu might want to read this document that gets into some reasons.

The PERC6 controller, or for that matter, any of the ones using the LSI 38xx or 2x08 controllers MUST use enterprise-class SATA (or SAS disks). LSI, Dell, HP, IBM, Intel, and i expect the other manufacturers that OEM boards made on this chipset simply do not qualify desktop class HDDs. Due to the TLER issue, they are not suitable.

So is any raid going to be reliable with my MB if I switched to raid drives?

Or only if I get a raid controller

David

The RAID drives will make it more reliable no matter what MB you use. Read the specs on the disks!
