Raid help please

I have an MSI k7t266 Pro2 RU motherboard with onboard promise raid controller and two IBM 40gig 60gxp hard drives... I would like to set my stripe size to something other than 4k... anyone know how to do this... any help in increasing performance would be greatly appreciated...running windows xp home... raid 0 btw...

Thanks

 

okay...so I figured out how to change the stripe size... my sandra scores are very low it seems... I have applied the PCI latency patch and run other tests like HD Tach and Winbench... could I be doing something wrong?

you must have your drives on separate channels on your raid card and make sure proper OS drivers are installed

if that's true, then it must only apply to certain raid controllers. I use an abit-th7ii raid mobo (hpt370 raid controller) and have 2 x 40gb ibm 120gxp's on the same channel on the same cable and my scores are what they should be. I ran HD Tach on a single drive by itself, my 2 drives in raid 0 on the same cable, and also again on 2 seperate channels. here are my scores

single drive - max 30880kps, min 15903kps, avg 28447kps

raid 0 on same cable - max 72736kps, min 16905kps, avg 46309kps

raid 0 on different channels/ cables - max 73126kps, min 15903kps, avg 46854kps

so for only using 2 drives, the performance difference is negligible. but anyway, i definitely agree on making sure you use the proper drivers for the raid card. windows likes to install its own driver and yes it works, but you lose alot of performance over the manufacturer drivers. also, what size did you set your stripe size to? mine is set to 64k, and i noticed before you could only set it to 4k but you never said what you have it set to now.

Might be a silly question, but are you using the correct IDE cables (80 wire not 40 wire)?
