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]

This drive can be used as a combined system and storage drive thanks to its fast 7200K rpm and enormous 3TB capacity. Recently prices for all large drives have been dropping and the 3TB Barracuda 7200.14 is currently a good choice in terms of both value for money and performance. Not only does the Barracuda have respectable sequential read/write speeds but it also goes head to head with the various green options, consuming a very reasonable 5.4W vs 5W (idle) on average for a "green" drive. That amounts to a tiny power consumption disadvantage and a lot more speed. Overall the Barracuda is priced aggressively and represents very good value for money. [Oct '12 HDrivePro]
