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. [Feb '14 HDrivePro]

This drive can be used as a combined system and storage drive thanks to its fast 7200K rpm and enormous 3TB capacity. Recently prices for all large drives have been dropping and the 3TB Barracuda 7200.14 is currently a good choice in terms of both value for money and performance. Not only does the Barracuda have respectable sequential read/write speeds but it also goes head to head with the various green options, consuming a very reasonable 5.4W vs 5W (idle) on average for a "green" drive. That amounts to a tiny power consumption disadvantage and a lot more speed. Overall the Barracuda is priced aggressively and represents very good value for money. [Oct '12 HDrivePro]
