One snapshot would help because, if EVERYTHING collapses, and you need data recovery, the snapshot provides a basepoint for the recovery. This should allow better recovery of metadata. Not that this should EVER happen -- it is just a good idea. I use Jim Salter's syncoid/sanoid to make snapshots, age them out, and send data to another pool.
I agree that ECC is a damn good idea - I use it on my home server. But, my lappy (i5 thinkpad) doesn't have it.
