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.
What may be happening here?
I guess it’s a MB problem - is is rather hardware problem or software?
What RAID controller should I buy to resolve the problem? - Is that a solution?
