Mirrored disks can be a two-edged sword.
The contents of one disk is automatically mirrored to the other which is nice if one disk fails. However, if there's an error, even if it's 'operator error', the error gets written to both disks.
If the disk controller goes bad and starts creating errors you have the same problem. The errors are written to both disks.
Still a good idea to have a totally separate backup disk or more to fall back on.
Enjoy!
