   Yeah, the 6Y series Maxtor is particularly bad. More than half of all
of them that I've had (a few dozen in total) have gone bad. The 7Y series
is a slightly better, but still well short of an acceptable failure rate.
   On the other hand, the Hitachi 7K250 and 7K400 series SATA drives have
worked quite well for us, with failure rates in the low single digits.
Seagate SATA drives also seem to be reliable, although they don't perform
very well.
