I see you went for Raid 0 then. As per what paradigm said.

As for the slow speeds, you have made sure you have the latest driver for the sata controller installed?
Try the Raid with 2 disks and see what the difference is. Your board could be limiting something.

Just because it's integrated onto the motherboad, doesn't mean that it's not actually still going through e.g. the PCI bus.
That graph leads me to suspect that that controller is bottlenecking on the PCI bus, however someone actually more knowledgeable with the Nvidia raid controller can probably confirm/deny whether it is on the PCI,PCI-E or system bus.
The Nvidia controller is integrated into the northbridge, the available bandwidth is in the gigabyte per second range.
Do that then run a long bench in HDTach.Is write cache enabled?
Right I managed to knacker one of the SATA ports on one of the drives so I'm down to three, but it's still wrong. I'm not sure why, latest drivers, write cache disabled etc. When I install either Vista or XP, even without any drives plugged in, somethings not right. Not sure what but something isn't...
I get similar results from a 2 drive setup on 680i based asus, looks like its an nvidia issue, intel boards are getting much better results. Im thinking of scraping any nvidia based motherboard at the moment and basicaly go back to an intel chipset.
I was using latest from nvidia's site, doubt its a driver issue, the issue is too consistant especially the transfer rate.
You know currently 680i chipsets have problems with many fast HDD's and fast RAM.
It will say Raid access failour when I run my ram at 1066Mhz. I guess its the same with the fast HDD's. Wait a bit for a better Bios update and Nvidia drivers

Well I got myself O&O defrag and the drives are in a pretty bad state of fragmentation. Should be finished soon.
I also used lifeguard tools and no errors found. As for write cache, I'm not going to disable it as it's good for Windows, plus it shouldn't hinder my score that much.

Raid5 is slower due to the parity, fastest disk configuration is Raid1+0 and using a good controller rather than on board.
I'm not really interested in redundancy as it's only the OS and games that go on the drive. Everything important will be backed up onto another drive.
Anyway, I'm still getting poor rates, even slower now then the ones in the screenshot.
