My experiences with RAID, especially HW-Raid is "mixed". Last week I got an DL360 G4 with some built-in HW-RAID(5) that returned "read errors" from the RAID to the OS without failing any drive(s). On an email server. Looks to me like a serious bug in the RAID-firmware. I even have found high-end RAID (Rio) whose memory did not deploy any ECC. One device did make stripes of zeroes into every block that got through it. Then there are HW-RAIDs which can detect silent bit-rot on your HDs and some that can't. > All of my database and fileservers currently use hardware raid (3ware > or LSI/PERC).

I currently trust linux SW RAID (MD) and ZFS more than any HW RAID. So almost all our file servers have been migrated from HW-RAID to SW-RAID or ZFS. Plan is to complement that with shadow volumes for some volumes which have data that need an way of "instant resore".
