The HGST Deskstar NAS is one of the few NAS drives to feature a 7,200 RPM rotational speed. This relatively high rotational speed helps the 4TB Deskstar NAS achieve a 4k read/write speed of 1.14/2.2 MB/s. 1.14 MB/s is actually the highest 4K read speed I have seen to date on a 4TB drive. In terms of sequential read/write speeds the Deskstar NAS clocked in at 161/144 MB/s which are also a reasonable set of scores. Overall the Deskstar NAS scored an effective speed of 116 MB/s which despite being 14% below the group leaders, is still second place for a 4TB capacity drive. With 4TB of capacity and an above average performance profile the HGST Deskstar NAS represents very good value for money. [Mar '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]
