That almost doubles the chances of losing data, and when you do lose it, you lose it ALL. RAID 0 isn't really a proper RAID (Redundant Array of Inexpensive Disks). I use RAID 1 with 2 WD RE4s. It, however, only protects against drive failure. There are other problems that can happen, like file system corruption, and viruses.

To protect against filesystem corruption use a filesystem with checksums (such as zfs), and to protect against viruses or accidental removal, use a filesystem with snapshots (say, zfs).
I automatically take a filesystem snapshot every few minutes, then keep one per hour for a week or so, then one per day for a few months, then one per week until I run out of disk space (all automatic).
So, if I accidentally remove a file it is very easy to restore it.
Also, redundancy is required if you actually want to keep your data, regardless of storage medium. RAID1, or, if you can live with slower storage but more space, RAID(5/z/z2).

How's ZFS support through FUSE (in linux)?

You are almost certainly better of using the native version from http://zfsonlinux.org/

^ Oh wow, thanks.
On subject.
I almost exclusively use my BD burner for archiving. I have a handful of old games that I will occasionally install with it, and I do a clean reinstall of Windows every 6 months or so. Aside from that, I don't need an ODD, but I still wouldn't call it obsolete, because, as mentioned, too many companies (MPAA members and RIAA members) are stuck on physical media. The only legal way that I know of to obtain music in a lossless format is by ripping a CD yourself.
