Nearly a year and a half ago, I had the chance to take a look at the 2TB Desktop SSHD. Like all standard SSHDs, the Seagate solution takes the massive capacity of a mechanical hard drive and adds NAND flash to it, allowing the drive to use a proprietary caching algorithm to speed up frequently used applications.
The Seagate Desktop SSHD has been on the market for a number of years now and as we mentioned in the original 2TB Desktop SSHD review, it wasn't long after that the 4TB variant was launched as expected. Setting this drive apart from the original 1 and 2TB solutions most notably is the spindle speed, as the original drives used a healthy 7200 RPM approach. The 4TB solution in the lab now is based upon the standard Desktop HDD and utilizes a 5900 RPM spindle speed.
Pricing and Availability
Above, we have the drives specifications pulled from the Seagate website. Starting form the top, we find the SATA 6Gb/s interface for the drive. Like the previous solutions, this 4TB drive uses the same 8GB of MLC NAND along with a 64MB drive cache. Average seek for read and write is listed as less than 12ms, while the average data rate comes in at 146 MB/s over the platters and increases to 190 MB/s when reading from the NAND.
The 4TB Desktop SSHD is manufactured with four platters encompassing eight heads with a load/unload cycle rating of 300,000. Power consumption of the drive is set at 7.5 watts operating, with idle hovering around 6.2 watts. Sleep and standby power are both set at 0.75 watts.
The MSRP of the Seagate Desktop SSHD in the 4TB capacity is set at $239.99 with a three-year warranty.
