I've got a new server with 2 mdraid RAID 1 arrays - one on spinning

Should I enable it on the SSDs?
Enabling SCT Error Recovery Control seems to be conventional and
recommended for RAID, regardless of drive type (HDD or SSD) . I have
it enabled on the HDD's in my md array.
Or are they not prone to failure in
such a way that it would be useful?

That looks like a high-end consumer SSD . I don't see anything
obvious in the specifications summary that would preclude enabling SCT
