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.
Market Positioning and Specification
This is how Seagate positions their Desktop SSHD –
SSD Performance. HDD capacity. Affordable Price.
SSHDs are now available for
your desktop computer. Get the speed
and kick of an integrated
solid state drive (SSD) with the massive
capacity of a desktop hard
drive – all at a surprisingly low price!
- Up to 4TB of massive storage
- Solid state speed for fast,
responsive system performance
- Innovative use of solid
state memory delivers affordable performance and capacity
- NAND Flash and HDD
technology work better together to deliver improved reliability
Here is the specification for the STxxxxDX001 series of
drives, which are available in 1000GB, 2000GB and 4,000GB capacities –
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
