portable hard drive fails from under use

Indeed yes I noticed that too but didn't want to say anything

Right, I missed your point. Yes that's true. But drives are cheap! Though SSDs are meant to last a few hundred years or so. I'll report back in 2300 and let you know how it's going!

I can't guarantee being able to reply.

But I do not regard that as a backup policy and I consider it makes a dangerous backup policy. When RAID fails, it often fails catastrophically. TBB lost an entire RAID system a while back.

IDNet's mail server failed a couple or so years ago, when two drives in a RAID failed simultaneously. In theory, the RAID should have provided failover, but the second failure prevented that. It was, undoubtedly, a very rare set of circumstances, but as an American friend of mine used to sat, Ship Hattens.

I'd also never trust RAID as a backup medium, I believe in keeping that simple, ie multiple drives which are physically stored off site.

This is why, when specifying drives for a RAID array, you never have all the drives from the same manufacturing batch.

Life should be easier, shouldn't it.

Or leave a cup of coffee on of the Array.
