Seagate Desktop SSHD Review

Seagate Desktop SSHD

The Seagate Desktop SSHD is a 3.5 hybrid drive that combines a high capacity hard disk drive with a flash memory to act as a non volatile cache.

Seagate Desktop SSHD

Seagate’s Desktop SSHD was one of the first 3.5in desktop hybrid drives to launch. Hybrid drives look to alleviate the lack of storage capacity available from SSDs by combining a mechanical hard disk with a smaller amount of NAND flash memory to speed up access times for frequently-used files. Thanks to technologies such as Triple Level (TLC) cells and vertically stacked chips, SSDs keep getting bigger, but the cost per GB of an SSD is still considerably higher than in mechanical disks and will likely remain so for a long time. Hybrid drives aim to be the best of both worlds in giving you the capacity of a mechanical hard disk combined with some of the speed advantages of an SSD.

Seagate’s adaptive memory technology learns the user’s data access patterns and adds the most-used data to the solid-state memory to speed up your system. The 4TB Seagate Desktop SSHD we tested is equipped with 8GB of MLC NAND for this purpose. The mechanical hard disk component consists of eight heads and four platters, which allows for the large capacity. The hard disk has 64MB of cache and operates at 5,900RPM; a common speed for very large disks.

The Seagate Desktop SSHD is also available in 1TB and 2TB configurations, and notably these both have faster spindle speeds of 7,200RPM. At 3p per GB for 4TB, 4p per GB for the 2TB disk and 6p per GB for the 1TB model, the disks still offer good value but are fractionally more than Seagate’s Desktop HDD and Western Digital’s Green drives.
