actually, i should thank you.  you brought
up a point that i've been thinking about
for some time.

i buy my drives online like everybody else.
my personal approach is to select a couple
of good performers in the capacity range
i'm intersted in and sort by (a) mtbf,
(b) ure rate and (c) duty cycle.  i'd stay
away from drives with 4 or more platters
if possible.

finally, beware of tech sites with storage sponsers
that might compromise their recomendations.
