For MythTV storage, you either value the video data enough to
have multiple copies, or you don't.
(I assume you value the database enough to run the standard
backup job daily, and store it on a disk that is not running
your database.)
If you keep multiple copies of the video data on different disks, then
it will be safe against a disk failure. If you don't, it won't.
Either way, there's no reason not to use NAS rated disks.
