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]


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]
