The WD Black (2010) is not a great performer, at least not in today's market. With peak sequential read/writes of 162/129 MB/s the Black lags particularly at writing. In terms of small file random 4K performance things are a little better with peak read/writes of 1.21/2.7 MB/s but these figures still lag the current group leaders and place the 2010 version of the WD Black well below average. A direct comparison to the 2012 WD Blue shows that the newer Blue not only outperforms on nearly every single benchmark but also costs less. [Jan '14 HDrivePro]
