Well, the 510 is a SATA drive and doesn't implement either command so
that would be an LSI SATL problem. I recall that we had some problems
with the LSI firmware blacklisting DRAT/RZAT on that particular drive so
I did the same in my libata patch.

I don't have any bugs open with WRITE SAME or UNMAP on recent LSI
firmware, though. We use it extensively here.
