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]

The new 3TB Seagate Barracuda 2016 (ST3000DM008) replaces its hugely successful predecessor, the 3TB Barracuda 7200.14 2011 (ST3000DM001). Comparing performance between the two models shows that the newer drive has 12% faster sequential speeds, comparable 4K speeds, improved mixed sequential speed and reduced mixed 4K speed. Overall, the effective speed is 12% faster on the 2016 model. Since there is normally little price difference between the two models the 2016 version is the clear winner especially for use as a backup drive with its impressive sequential read and write speeds of nearly 200 MBps.
