dont put more than 10-12 disks in a single raid stripe and allow at
least 10% hot spares. my monster raids built from 3TB SATA drives
rebuild from a single drive failure in about 12 hours, and have 2 spares
online, so it would take 3 drive failures in less than 12 hours to take
the file system down. never rely on cold spares in storage, they won't
be there 3 years from now when you need them, and every hour the spare
isn't replaced, is another hour added to the rebuild time leaving you
open to more fail.
