Raid is most often used on large, 24-hour systems where any downtime
at all is too much.  Such systems are not expected to be rebooted
often: what is important is the recovery time after _unplanned_
reboots, such as power failures or crashes.  For user-visible servers,
long recovery times after these events are unacceptable.
