This is the current version (2013) of Western Digital's best performing, Black, consumer storage drive. A comparison between the 2013 and 2010 versions shows that core real world performance has improved by around 15%. The 38 month old 2010 FAEX Black is also slightly more expensive at the moment, probably because retailers are slowly running out of stock. With average sequential read/write speeds of 150 MB/s and read/write 4k speeds of 0.8/2.9 MB/s the 2013 2TB WD Black has a solid performance profile but it's slightly overpriced. There is better value available amongst other drives in the group test[Jan '14 HDrivePro]

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]
