Re: SATA SSD + RAID

I've inherited a system which has an Adaptec 2420SA RAID controller and 4x SSDs running in RAID6. There's no end to problems experienced with this setup; a disk seems to time out and get ejected from the controller at least every week. It's not always the same disk though, and I've tried replacing each of the SSDs with their spares, to no avail.

Are you confident the disks are the problem? Since this is hardware RAID, you should have a spare RAID card. Swap that in, and see if the problem goes away. If it does, RMA the original card. If you have a complete backup *server*, swap the disks into it and call it the master. That way you can test for faults in the hotswap backplane &c as well.
