The Seagate Desktop SSHD is a Solid State Hard Drive (SSHD). The 8GBs of MLC NAND flash built into this model help facilitate better performance than a purely mechanical drive. Peak sequential read/write speeds are above average at 190 MB/s. The 2TB SSHD has consistently demonstrated class leading 4k random write speeds in the region of 5.0 MB/s. 4K read speeds are in the region of 0.7-0.9 MB/s which is well above average, but not record breaking. Overall the performance increases attributable to the NAND flash are very noticeable in the area of small file 4K performance where the SSHD dominates the competition. In terms of sequential speeds, the Seagate also offers better average sequential performance than most mechanical 2TB hard drives. From a value for money perspective, the 2TB SSHD is well above average, it has a brilliant 4k performance profile, strong sequential speeds and only a slightly above average price. [Dec '13 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.
