Either/or.  In general the SAT (SCSI/ATA translation) spec posted 
publicly on http://www.t10.org/ gives the suggested transformation into 
ATA commands.  And yep, you guessed it -- send diag morphs into SMART.

I doubt I'm motivated enough to enhance send diag, but others are 
encouraged to do so.
