Description

Out of an abundance of caution treat

  • Samsung 843T Series SSDs (MZ7WD*)
  • Samsung PM851 Series SSDs (MZ7TE*)
  • Samsung PM853T Series SSDs (MZ7GE*)

as known having broken NCQ TRIM support as they appear to be based on
the same controller technology as the 840 and 850 series.

I've had at least one report of the PM853 being broken, so err on the
side of caution for the above drives. The PM863/SM863 appears to be
based on a newer controller, so give it the benefit of the doubt.

If this is being done because of the Samsung 840/850 Trim bug fiasco last year (2015), that was confirmed to be a bug in the Linux RAID code and not a bug in the 840/850 firmware (Samsung identified the issue, the md maintainers confirmed it).
