I had the same feelings about drive lifespan... and I agree that the data isn't exactly mission critical... anything that I would want to keep would be exported on DVD or <insert media here>. I'd rather sacrifice data integrity for my media than performance... It's going to be fun to play with this setup... as I've done this with old bt878 cards on low-end systems as a test... but never on real production quality equipment.

If these are new drives, I suspect that the lifetime of the drive is longer than the lifetime of his currect mythtv install. Maybe if you've been recycling the same drives through systems for the last ten years you can expect them to die on you, but seriously, two new drives are going to last a while.
<br><br>RAID5 for a bunch of television shows is overkill. This isn't mission critical data here, and the disks in all likelyhood are going to last at least a few years. Maybe I'm just lucky, but I've never had a drive fail inside a desktop system (I've had a laptop drive fail when the laptop failed to go to sleep when the lid closed and then went for a journey on the subway, but those are different circumstances). I've been running four of my drives for over five years now, and they still work fine. Although, at four years, I did start mirroring the data on another set of drives.
