On my server running Debian stretch,

Two identical SATA disks with 1 partition on each drive spanning the

/dev/sdb1 form a RAID-1 /dev/md0 with LVM on top of it.

sda was last self-tested at 21808 hours and is now at 51289.
sdb was last self-tested at 14254 hours and is now at 43740.
And those were short (a couple of minutes) self-tests only.
So these drives have apparently only ever run one short self-test.
