But that doesn't take care of the time issue. I will admit that if a drive fails I will have to google for the instructions to proceed from there. When I first set it up, I read the info, but since I never had to use it I've completely forgotten the specifics. And in hindsight I should have labeled the disks so I know more easily which one failed (when one fails). Next time, I'll do it right. :) >> I am really curious >> if there are any gains to be made on my own system... > > Me too, so post back after you've done it ;-) I have a dmcrypt on top of the (software) RAID5, so speed is not so much of an issue in this case, but reducing physical wear & tear on the disks would always be a good thing. Maybe someday if I am brave I will try it... but probably not until I made a full backup, just in case.
