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.

The ST1000DX001 is a Solid State Hard Drive (SSHD). There is 8GB of MLC NAND flash built into this model which helps facilitate better performance than a purely mechanical drive. The peak sequential read /write speeds of 190 MB/s are around 10% higher than average for a mechanical drive, but no where near typical SSD speeds. We have seen peak 4k write speeds as high as 5.72 MB/s, which is very impressive and to date the highest 4k read speed is 1.24 MB/s which is less impressive but still above average for a top end mechanical drive. The performance increases attributable to the NAND flash are primarily noticeable in the area of small file performance and the Seagate offers only marginally better sequential performance than other mechanical 1TB hard drives. Overall the ST1000DX001 is a very solid performer and bests the group average by 30%. The larger 2TB version (ST2000DX001) has similar performance but represents even better value for money.
