MB - RAID problem

Hello

Motherboard - ASUS P8P67 EVO R3.0 Intel P67 LGA1155
4 HDDs - WD Caviar RE4 2 TB WD2003FYYS 64MB (RAID edition).

I have a RAID 10 setup out of 4 HHDs on build-in on-board Intel RAID driver.

It was working brilliant for a month. Then suddenly, during startup, some strange, unnatural continuous sound (resembling a tractor working) came from one of the drives and the computer stopped booting up for a while. After boot-up this sound and lagging occurred very frequently. Then Intel RAID driver indicated a disk malfunction and disconnected the drive. Indeed, the disk indicated some SMART errors (write errors in particular).

I disconnected the drive cable - everything came into perfect life again. I thought it was a HDD problem - but it wasn't.

The same problem started with another drive of the RAID array that was connected to different port.

1. What may be happening here?

2. I guess it's a MB problem - is is rather hardware problem or software?

3. What RAID controller should I buy to resolve the problem? - Is that a solution?

4. BTW. The system (Win7) is on separate Vertex-3 SDD. Can I achieve 6 gbit transfer despite the Marvel onboard?
 
It sounds to me like you have more than 1 bad hard drive. Can you post the SMART.

It could also be a problem with your power supply.
 
Two disks failing (workstation class) out of 4 seems so not likely...


The Smart indicates problems in the following parameters:

Ultra ATA CRC Error Count - 2
Write Error Rate - 6


The power supply is Dark Power Pro 1200 W.
 
They are not "workstation class" drives, they are nearline-class, just fyi.
I do agree with you though, having two of those drives fail at the same time, though not impossible, is rare.
I also doubt it is the PSU as you would be seeing more signs of failure.

I think your main problem is the controller on two of the SATA ports: Marvell 9120.

Those Marvell controllers are cheap and do not last, especially with SATA-III.
My suggestion to you, if you do not want to send the mobo back, would be to get a FakeRAID PCI-E controller card. For HDDs, it does not have to be SATA-III, if you want to save on the cost.

If they are from the same batch or shipped together I see this easily happening.
