I bought a RE3 a year ago. During that time I saved for 2 C300 drives for the onboard 6GB/s only to find it was not compatable with the Marvell chipset. So I returned them to newegg. 3 months on I buy 2 120GB 510 drives to go in to the system. Only to be let down.
First the marvell controller clearly states its a 6GB/s but on the bios load screen informs you its limited to 5GB/s because its on one PCI-E pipeline.
Second when you raid anything at all on this controller is impacted very very badly. You get less seq reads than you do if you ran the drives standalone. This is a big issue to me and I am sure anyone else who owns it. I was sold a board on the promise of twice the bandwidth of the Intel raid. This is clearly printed in the manual and on the Asus website. But that will never happen being handicapped to 5GB/s. Also the issue of it running in raid 0 is a huge issue. Everyone knows the Marvell controller can run raid 0 fine because Highpoint use it on some low end raid boards (640) so the issue is with how Asus implements it.
I have contacted Asus and they happily inform me that not only do they know of this issue they plan to do nothing about it. They offered to exchange the board for the same model but its still going to perform the same way.
Can you help?
