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 1TB Barracuda 7200.14 boasts impressive peak sequential read/write Lab speeds of 195/193 MB/s. These best case burst speeds indicate what the Barracuda is capable of under Lab perfect test conditions. Our real world benchmarks have been sourced from hundreds of users and give a better sense of how well this drive actually performs on a day to day basis. The 1TB 7200.14 has an average UBM sequential read/write speed of 147 MB/s, which is a superb result, especially for a budget drive. With 4K random read/write speeds of 0.77/1.53 MB/s small file performance is also respectable making the 1TB Barracuda a very good all round performer. In terms of value for money the relatively small 1TB drive is not as good value as its larger 3TB sibling but in the 1 TB category this is one of the best value for money drives available. [Jan '14 HDrivePro]
