   I can't seem to note any physical (e.g., dimensioning, connector placement,   
   fastening) differences between the two types of drives (other than the   
   obvious difference in connector geometries).   
      
   I'm trying to understand why there would be different *sleds* for the   
   two types (SAS vs SAS/SATA) as, mounted, there seems to be no difference.   
      
   All I can imagine is some mechanism that prevents one type of sledded   
   drive from being installed in a machine that doesn't accept that type   
   of drive (I could see a SAS drive buggering a SATA-only mating connector).   
      
   And, of course, a machine that can't take advantage of the SAS interface   
   would be foolish to accept such drives.
