How about every day?

Quick guess how often disks need to be replaced when there are thousands of them. ;)

You can replace disks once a month or less. That's not an on-call thing, even if you do make your $200k admin do that grunt work.

Also for one or two thousand disks I would expect less than one failure per week.
