WD Blue hard drives have a multitude of features including third generation SATA interface with 6 GB/s transfer rate, plus rock solid performance and ultra-cool and quiet operation.
A sata 2 drive tranfers at only 3 GB/s THAT is a big difference, and that post you posted Gary was from 2011, 4 years ago, going on 5 now.
WD Black drives are faster than Blue drives.

That is another reason I bought this computer, its all SATA 3 connections. My 2nd computer only has SATA 2 .
