The 3TB Toshiba DT01ACA300 is 3.5" desktop hard drive. Like its 2TB sibling, the DT01ACA300 sports a rotation speed of 7,200 RPM and has a relatively low peak/idle power draw of 6.4/5.2 Watts. With peak sequential read/write speeds of 197/183 MBps and peak 4k read/write speeds of 1.17/2.19 Mbps the 3TB DT01ACA300 achieves an effective speed of 143 MBps which places the DT01ACA300 amongst the top handful of 3TB drives. Pricing of the DT01ACA300 is also very aggressive which makes the DT01ACA300 a superb value proposition. Comparing the DT01ACA300 and Barracuda shows that the DT01ACA300 is marginally faster but also slightly more expensive. [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.
