I have had my GA-P35C-DS3R and used to have it set with 4*500gb drives in raid 0 and had good performance as expected.

Its an early rev 1 style board, although not exactly as same in picture.

I dont have a firewire socket.

My MB failed with a corrupt bios and had to be returned for repair, and it was done very well in fact one of the plastic clips on my ram slot was also repaired, thanks very much Gigabyte for such good service.

But, I have only used the mb with a single drive since that time, last night i atttached 4*80gb drives and tried to set them up as raid 0, now I should add I am using ide/sata converters as i made the mistake of ordering ide drives (doh), but the drives have performance of about 80mbps continuous read, when all 4 are in raid 0 this FALLS to around 22mbps for the array !!

with 2 drives in raid 0 the fall is from 80mbps single drive to 60mbps for the array

I have tried raid 0 and 5, I have tried setting the raid up from intel raid manager and from the bios raid manager, same result.

anyone have a clue?

anyone know what software I could use to try and find the problem?

I'd like to take the easy way out blame the ide converters but as they do 80mbps on the same sata cable as when in raid it seems to be something else.
 
This isn't really the correct sub-forum for the question, you'd be better off in the hard drives sub-forum.

Ignoring the fact the RAID0 is a bad idea for anything but a scratch drive, I'd blame the PATA-SATA convertors until proved otherwise.

Don't use converters ever, except the occasional DR scenario where you need a one off data yank/image.

If you orederd IDE drives best bet is just to accept you cocked up and re-order the correct drives. Stick the IDE ones on Ebay/Members market and try and recoup something on them.
