I personally don't count on disks to run for more than a year after
their
warranty has expired.
Depends on the drives ... in my experience, clearly a case of "you get
what you pay for."
I have SCSI drives which are way beyond their warranties -- (by 4 or 5
years), and other FireWire drives that haven't lived as long as their
warranty!
Put another way, SCSI drives tend to be more expensive because they are
subject to more rigorous testing before their sale, and have claimed
MTBF ratings well over the 1,000,000 hour range (2 years) common on
cheaper drives.
Environment and usage patterns also are related. Drives that are
powered up and down constantly, tend to fail much sooner than those
that are simply powered up and left running "forever." Drives that
operate in a relatively constant ambient temperature environment tend
to "live longer" than drives that live in a "normal room" environment,
where the "heat of the day" pushes the ambient temperature into the
high 80s or 90s.
I don't know that any of my drives are new enough to support SMART
technology, especially since they are almost all SCSI drives, which
doesn't really "support" SMART in the first place. Guess I'll have to
play.
