I would generally agree with using a normal single drive for most home systems. However this is a software development system and I like the added safety of a raid setup. I do have proper backups kept in a fireproof safe as well.

@davpen: RAID doesn't provide safety, it provides performance and/or redundancy. If you want safety you're better off in a software-RAID mirroring configuration than a RAID-5 setup.

By safety I mean redundancy as in some protection from a drive failure. Software RAID mirroring (RAID 1) is not any better than RAID 5 (software or hardware) in providing protection against a drive failure. Of course using a RAID array is not a substitute for regular backups it is just an added layer of protection.
