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]

The 1TB Barracuda 7200.14 boasts impressive peak sequential read/write Lab speeds of 195/193 MB/s. These best case burst speeds indicate what the Barracuda is capable of under Lab perfect test conditions. Our real world benchmarks have been sourced from hundreds of users and give a better sense of how well this drive actually performs on a day to day basis. The 1TB 7200.14 has an average UBM sequential read/write speed of 147 MB/s, which is a superb result, especially for a budget drive. With 4K random read/write speeds of 0.77/1.53 MB/s small file performance is also respectable making the 1TB Barracuda a very good all round performer. In terms of value for money the relatively small 1TB drive is not as good value as its larger 3TB sibling but in the 1 TB category this is one of the best value for money drives available. [Jan '14 HDrivePro]
