Just to chime in with agreement on Thierry's comment that "Reallocated
sector count" is probably the most useful single indicator of future
failure on a disk

I have one (Seagate, or course) 8TB disk with a non zero Reallocated
sector count in service, but:

a) Its running in a system providing a local mirror of ~16TB of data
via syncthing
b) Its in a ZFS RAIDZ pool

... which is why that system has the less-than-entirely-trusted Seagate :)
