tl;dr

• The Elements line is a disk drive, less lardon software & services
• The My Passport line & extensions has lardon software & services, and some colors.

Get Elements, you don’t need all that other goo.

  Better technical details than the vendor’s literature; yet seems to hint that only My MyPassport uses the smaller 2.5″ HDD (that the Essential line uses 5″ HDD).  Yet the WDBU6Y0020BBK-NESN at Amazon appears to use 2.5″ HDD.
