Raid 0 Sistem Kurdum Performans Düştü

Thanks everybody for Your help and ideas!

I solved the problem last night ... or was it this morning already ??? :>

First thing I did was install the newest unofficial BIOS by Kingpin - 0909 I believe it is. Than I remembered, that RaidXpert and Raid BIOS itself told me, that my SSDs are connected to SATA Port 1 & 3, and the other 2 Caviars in another Raid0 array to ports 2 & 4. I doble checked the fine print on the board as well as in MoBo documentation to make sure wchich port is waht number. Sure enough according to that I had my SSDs on port 1 & 2 and the other array on ports 3 & 4. I thought I'll gie it a shoot and try switching the cables.

Now that's what the manual tells You:

1---3---5
|==|==|==|
|==|==|==| *|==| - Sata port biggrin.gif
2---4---6

Clearly that's not what the raid config says.
I switched the cables. Checked if now in Raid BIOS my SSDs are number 1 & 2 and other array 3 & 4 - in fact they were - and resumed to windows for benchmark.

Voila! Now I get 890MB/sec writes and pass 930MB/sec in reads!
It's still not as good as Intel controller that beats 1GB/sec reads, but good enough for me to sleep better smile.gif

I might try to unhook the 2 HDDs from the RAID, since they might be stealing some bandwich from the SSD array and see if that improves the results any. But if not, I hope some futere driver upgrades will make the performance close up on the Intel controller and beat the 1GB/s mark.

So here we have it. When You decide to Raid your SSDs or HDDs using AMD MoBo, pay attention to the right cable routing. Obviously, the Crosshair V manual is missleading in this case. The correct SATA port arrangement is:

1---2---5
|==|==|==|
|==|==|==| *|==| - Sata port biggrin.gif
3---4---6

Connect the Raid array's disks to ports 1&2 (or 1,2,3 and than 4 - depending on number of disks). Obviously when I had my 2 SSDs on ports 1 & 3 it limited the performance drasticaly.

Hope that helps!

Cheeers !
