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]


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]
