Question to folks or anyone with experience: does it make sense to use raid (hardware or software) in a homelab setup? Or instead, put the parity disks to either extra data or backup? The way I see it, raid is mostly good for staying up when a disk is broken. If something breaks in my personal setup, I'll just pause everything and get to work, I don't need 99.95% uptime.

So instead of having raid + backup, invest all in backup and just replace the faulty disk.


@yarmo I started using RAID on home workstation / lab machines after a couple of disk failures, as it was annoying spending the time to recover it all twice. I had a fairly complex virtual cluster for experimenting on and some other things which were a pain to recover. Guess it depends on how long it’d take you to recover from backup, and how much it’s worth to avoid that.

@yarmo of course since I started using RAID sets I haven’t had a single disk fail (6 yr and 2yr old drives in 2 arrays)... so I’ve not really saved any time by having the RAID heh.

@yarmo that said, having raid in a home lab was great for playing with breaking and recovering things. Which certainly made me happier dealing with things at work.
