[NBLUG/talk] More questions about RAID

[Walter Hansen]

It probably would have crashed anyway. The raid would have merrily 
duplicated the bad information. RAID does not protect you from bad data. 
If something introduces bad data into your file system the raid will be 
very efficient in duplicating it to the other drive.

Which is the other big point. RAID is no replacement for regular backups.
