RAID 0 Higher Risk of File Corruption Than with Two Separate Drives?

I realize that if you have two individual drives and only one mechanically fails, you still have the other one intact. While if you have a RAID 0 setup, if one drive breaks, you lose data on both drives because files span across drives.

What I'm not sure about is, is RAID's reading and writing process inherently more unreliable than writing to a single drive?

I'm not talking about mechanical failure, rather the possibility of additional read/write errors being introduced by using RAID.

In general, but especially when it comes to editing systems, Raid 0 should be avoided because, as you suggested, Peter, if one hard disk fails, your project is corrupted and, in most cases, unlikely to be restored. Raid 5 is the best choice, because all you have to do is replace the bad disk and continue to work.
