A RAID array isn't a universal solution to all disk related problems, though, is it? I mean, we were talking about buggy firmware earlier on in this thread - if a drive which is part of an array returns corrupted data, without acknowledging it, then you'll read corrupted data from the RAID array. Also, an array of unreliable drives doesn't make a reliable array.

Now that the Smart Suite S.M.A.R.T. applications are unmaintained, would there be any chance of implementing S.M.A.R.T. in to the kernel IDE code? I know the IDE code is already a nightmare, but it would be a nice feature. S.M.A.R.T. is terribly under used at the moment - most people don't even know what it is. Infact, I could be wrong, but isn't a subset of S.M.A.R.T. implemented on modern SCSI disks, too?

Monitoring of any kind is always a nice feature to have...
