Odd Raid performance - GA-P35C-DS3R

[flez]

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.

Hi and welcome.

You might like to check your link as it isn't working at the moment.

Certainly an unusual problem there. Not one that I can say I have come across before. Try installing the RAID0 with just two drives first and see what happens there.

Yes odd the link failed,

Although I have never understood why its shown with a firewire socket.

Only thing really different is the drives and the bios, before I was on f11, which seems to have gone from the site for some reason, I may have it still somewhere in an old backup, it may be worth me rolling back to try that.

Usually a BIOS version that goes missing off the site is because it has been found to have problems and so it is withdrawn. As you say though it might be worth trying another BIOS version.

Although I have never understood why its shown with a firewire socket.

It is probably just a case of the pictures got mixed up.
