If you're buying the same model drive from the same manufacturer of
the same capacity, then you're getting the same quality with some
different silicon screwed on to it.

-Peter

Convention dictates that when constructing
a true SAN one should buy drives from different
manufacturers.  Doing so addresses
the concern that a particular drive will not be the same
as the next drive in the SAN.  The reasoning behind that
is if drives are from different manufactures chances are
less likely that the drives will fail in a similar fashion
in a reasonably short time span.
