In my experience, they seem to be reliable while both disks work, but when a disk needs to be rebuilt the RAID BIOS seem to pick the source disk at random, as opposed to something radical like using the only valid disk as the source. Originally I thought this was a FreeBSD issue, but replies to my post sugggested it was a common problem, and not just limited to FreeBSD. Indeed, on the hardware I was using (a Sun X2100 server), Solaris had the same problem, and about 50% of the time you'd end up with corrupted or blank disks after a rebuild. Sun have now stopped claiming in the specifications that these machines support RAID, and I'm now using FreeBSD pseudoraid on them. Gavin
