Raid 1 - look at dm-integrity. That should make scrubbing (hopefully)
redundant :-)

I might at last soon get my new system up and running (got a shop to
look at it - dud motherboard :-( Of course it's now out of warranty and
my supplier has gone bust, but if the shop say it was dud from the start
I might be able to claim something ...

But that means I'll have a test system - I've acquired about 6 x 1TB
drives - so I shall be playing with some slightly more heavy-duty raid
configs :-)
