You don't *need* identical drives, the point was that it doesn't make
much sense deliberately buying drives from different manufacturers.  If
you are interested in avoiding catastrophic failure checking your drive
condition with S.M.A.R.T smartmontools[1] is also a good idea.  This
will give you pre-failure indicators which may allow you to preemptively
replace a drive before it fails.

You are talking about the merits of backup versus raid.  This is pretty
analogous to ABS breaks(raid) and airbags(backup).  ABS might stop you
having an accident, airbags will lessen the impact.  If you have the
option of both, which you do, you should do both.
