This is the current version (2013) of Western Digital's best performing, Black, consumer storage drive. A comparison between the 2013 and 2010 versions shows that core real world performance has improved by around 15%. The 38 month old 2010 FAEX Black is also slightly more expensive at the moment, probably because retailers are slowly running out of stock. With average sequential read/write speeds of 150 MB/s and read/write 4k speeds of 0.8/2.9 MB/s the 2013 2TB WD Black has a solid performance profile but it's slightly overpriced. There is better value available amongst other drives in the group test[Jan '14 HDrivePro]

This is the most recent version (2013 FZEX) of Western Digital's best performing consumer storage drive, its predecessor was the WD1002FAEX which is now four years old. With average sequential read/write speeds of 150 MB/s this version outperforms its predecessor by a whopping 50%. Small file random 4K speeds have remained broadly unchanged with average read/write rates of 0.9/2.19 MB/s. Overall the 2013 WD Black has a very good performance profile and it also represents reasonable value for money, at least in the 1TB category. There are some good alternatives to the 2013 Black including the 2012 Blue. Looking at the 2013 Black vs 2012 Blue shows that both drives have similar performance. Power consumption (6.8/6.1 Watts active/idle) and noise levels (29.5 dBA) are also identical making it a tough call between the two. There is however, as always, better value amongst the larger capacities. [Feb '14 HDrivePro]
