ALL drives have hiccups when there's absolutely
nothing wrong with them. What are the manufacturer's error figures?
Expect at least one error every two or three complete passes of pretty
much every large big disk nowadays?
i don't expect any SMART error at all and if one hits after years of
uptime fine that the drive don't fail completly - but would i trust it? no!
I have multiple drives (Hitachi) which have developed around 3 to 10
reallocated sectors, and then just continue to work for years, not increasing
those further. Throwing them away would be uneconomical.
better safe than sorry
in the past 15 years i replaced 6 drives on 8 machines (each 4 disks)
while some are running since 2011
on every location with machines i am resposible for is at least one
replacment disk, switch, order a new reserve disk, case closed
Generally though, if you are way too concerned about individual drive failures,
it could be a sign that you do not have a robust enough backup scheme in place
my backup scheme is perfect but my personal lifetime is much more worth
than a disk costs these days - the backups are regulary testet and in
the past 20 years i didn't need them which is a good thing
no backup on this planet contains the last 30 minutes of work besides
that outtakes typically happen in the moment where you have no time to
deal with such events
come on a restore a backup in a production environment, your customers
will be not much thankful when they lose the last 30 minutes of all
mails and work....
