And the drive inside those drives is a random drive, it can be a Caviar Blue, a Caviar Green, a Caviar Black

As the others have covered, the model number breaks down as follows:
WDBACW0020HBK-NESN...
WD = WD... that's a no-brainer
B = this is a branded product
ACW = USB 3.0 My Book Essential
0020 = Drive Capacity: 002.0
H = 3.5-inch form factor, capacity unit is TB, one drive per enclosure
BK = Black
Everything after the dash is for WD's internal use... it does not designate a different model... or really anything anyone other than WD could possibly care about.
But, for nosy folks:
N = Sales Region: Pan-America
E = External
SN = Standard Packaging
So, the only difference between an EESN, a NESN, and a SESN (or any of the other xESN markings),
is where the original vendor who received the drive is located... E being Europe, the Middle East and Africa, and S being Multi-City Asia.
