The 2TB Toshiba DT01ACA200 is a 3.5" desktop hard drive. This model sports a rotation speed of 7,200 RPM and is reasonably power efficient for a 2TB desktop drive consuming just 6.4 Watts when loaded and 5.2 Watts when idle. The DT01ACA200 has impressive performance with peak sequential read/write speeds of 193/182 MB/s and peak 4k read/write speeds of 1.16/2.28 MBps. These raw figures produce an effective speed of 141 MBps which ranks the 2TB DT01ACA200 amongst the top handful of 2TB hard drives. Not only is the 2TB DT01ACA200 a great performer but it is also priced aggressively and therefore represents superb value for money for a 2TB capacity drive. Comparing the 2TB and 3TB versions shows that performance is very similar but the 3TB offers 50% more capacity for just 25% more cash which makes the difference between good and great value for money. [Nov '14 HDrivePro]
