Dear Jim,

You work for a company that sells RAIDs. You SPAM all the newsgroups 
with advertisements about your company. However, looking at your reply 
I'd be very wary of buying anything from such a "raidexpert".

Jim, let it be known that a hot spare drive in a RAID 5 setup does 
NOTHING to protect from a failure of more than one drive at a time. What
it does do, however, it minimizes MTTR (Mean Time To Repair) because
most raid controllers will automatically initiate a rebuild of a failed 
drive onto a hot spare. Should another disk fail while the rebuild is 
still in progress - the RAID set and all the data on it will be lost.

Regards,

RAIDER
