I'm currently raided (Raid 1, 2 disks mirrored). Presumably I should do this again?
Personally I think RAID is just a nuisance which will make a disk failure more difficult to clear up than otherwise. Make sure important stuff is backed up (e.g. /home and /etc) and then just have 'ordinary' disks.
There is no substitute for backups. That said I find software raid (mdadm) and RAID1 to be very easy to work with, and very easy to migrate between machines etc. I would never use hardware RAID these days because I need to be sure I can access the data in different hardware if it comes to it, and I'd likely avoid RAID5 etc where each single disk doesn't contain a coherent set of data, but with mdadm RAID 1 I've never had a problem replacing disks or taking a disk out of a failed machine and accessing its data in different hardware. LVM on the other hand...
I'm a big fan of RAID ever since I had both disks fail within a few days of one another in my SunBLADE 2000. Didn't lose a single byte. OTOH, for some reason I've never bothered implementing it on my current Linux machine.
