It's a Samsung Evo 850 250gb on sATA that has SMART, but Samsung's own diagnostics app Magician does seem seem to support Macs. Huh.

I don't know whether Samsung was too lazy to write a Mac version of  "Magician", or if they figured that it wouldn't do much good.  USB and Firewire enclosures often do not pass S.M.A.R.T. status back to a computer, so external drives probably wouldn't report S.M.A.R.T. status.  Most recent Macs come without internal user-serviceable drive bays; thus Samsung may have figured that Mac customers would all be using external disks.

Samsung does claim that the 850 EVO supports S.M.A.R.T status.  So it is puzzling that Disk Utility can't read it from an internal 850 EVO SSD.
