The 1TB Toshiba DT01ACA100 is a 3.5" desktop hard drive. With a rotation speed of 7,200 RPM and peak/idle power consumption of 6.4/3.7 Watts the DT01ACA100 is a reasonably power efficient desktop drive. The DT01ACA100 has peak sequential read/write speeds of 175 MBps and peak 4k read/write speeds of 0.76/2.06 MBps. These figures produce an overall effective speed of 132 MBps which places it around the middle of the 1TB pack in terms of typical consumer performance. The larger capacity variants of this drive are both faster and offer better value for money[Nov '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]
