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]


Hard Drive Rankings (Price vs Performance) March 2017 HDD Rankings.

Welcome to our consumer Hard Drive comparison. We calculate effective speed which measures performance for typical consumers. Effective speed is adjusted by cost per GB to yield value for money. Calculated values don't always tell the whole picture so we check them against thousands of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top HDDs. Share your opinion by voting. [HDrivePro]
