Review: Seagate ST2000DX001 2TB Desktop SSHD

Welcome to Myce’s review of the Seagate ST2000DX001 2TB
Desktop Solid State Hybrid Drive (‘SSHD’).

We recently reviewed Toshiba’s latest SSHD offerings for
mobile devices, in a 2.5in form factor, and found them to be impressive
performers.  Today, we review Seagate’s offering for Desktops in a 3.5in form

At the heart of the SSHD value proposition is the idea of
marrying the low cost per Gigabyte of a traditional rotating magnetic disk
(HDD) with the speed of NAND Flash Memory to deliver an SSD type user
experience.  The key to success is a caching algorithm that intelligently
places a specific user’s most frequently accessed data in NAND memory so that a
higher proportion of data access is performed at SSD like speeds – Seagate
refers to this as its ‘Adaptive Memory technology’.

The Seagate Desktop SSHD has 8GB of Toshiba MLC NAND memory
married to an inherently fast Desktop 7200RPM HDD.

Here are pictures of the drives that I used for the purposes
of this review –

On the left is the 2TB Seagate Desktop SSHD.

For comparison purposes I used a 2TB Seagate Barracuda
(ST2000DM001) traditional HDD (pictured centre above, and hereafter referred to
as the HDD) and an OCZ Vertex 4 256GB SSD (shown right above, and hereafter
referred to as the SSD).

(For interest – I use two Seagate Barracuda 2TB HDDs in my
Z77 Desktop system to hold my first level of regular backups – you can see in
the picture that I have not removed the rubberised screws used to mount the
drive in my Desktop’s chassis)

Here is a picture of the underside of the SSHD (left) and
the HDD (right). You can see that there is little or nothing to visually tell
which is which and it is easy to imagine that they rolled off the same
production line.
