Note that there is a difference between drive failure and media data
loss. In a system which has been running fine for a while, the chance
of a second drive failing during rebuild may be low, but the chance of
block-level media failure is not.
However, computers do not normally run in a vaccum. Many failures are
caused by something like a power glitch, temperature cycle, or the
flap of a butterfly's wings. Unless your environment is completely
stable and the devices are not dependent on some of the same things
(e.g. power supplies, chassis, SATA controller, air conditioning) then
what caused one device to fail may very well cause another device to
fail.
