This surely depends on the type of hardware used. If the disks are not true "enterprise" grade (e.g. ordinary SATA drives) then scrubbing more often is likely warranted since these are much more likely to exhibit user-visible decay over a period of time and the scrub will find (and correct) the decaying bits before it is too late. The enterprise-class disks should not require scrubbing very often. Enterprise disks may be almost as likely to go entirely belly up as they are to produce a bad sector.
