Ah, but are you sure you can get to it the same day?

If it's in a datacenter at work it should be easy, except maybe over a
long weekend...

If it's in a telco station in the boonies or driving around Mars you're
not in good shape to just hop out and pop in a new drive :).

In any case, we can leave all these questions for the people who're
actually needing to double mirror things.

/me pats his RAID 5 and remembers to keep working on his offsite backups.
