Seagate Laptop Thin SSHD 500GB Review

by seo bhartirohila

The Seagate Laptop Thin SSHD 500GB is aimed at computer or laptop owners who want an economical and high-capacity solid-state drive. This SSD is 2.5-inch in size, has 5,400rpm, and possesses 8 Gigabytes of NAND flash in order to enhance performance. This SSD is the successor to the previous Momentus XT augmented laptop hard disks.

The device we are using for the review is of 500GB capacity, which is only 7.5mm thick and can fit within any ultra-portable laptop. Also, a 1 Terabyte variant is available too, but it has 2 platters, making it a thicker 9.5mm, which ultimately means that you will require a greater laptop to house it. Following are some of the details about this SSD

Architecture and Design

The Seagate Laptop Thin SSHD 500GB provides overall improvement and boot time somewhat comparable to other SSDs at a fraction of the cost. The drive has data transfer speeds less than most typical hard drives. This device is designed specifically for super compact desktops and laptops that focus on everyday computing requirements rather than data-moving-intensive tasks. Definitely, you do not want to utilize it in an external storage application or as a secondary device.

This Laptop SSHD is made to be plug-and-play. It will function with your selection of operating systems – you do not need to worry about compatibility – the SSHD is ideally suited to old generation laptops and backward compatible in need of a speed injection.



We tested this Thin SSHD for Laptop both against Momentus XT 750GB and SSDs, and it provided mixed results. In boot time, the drive did well, taking only 15 secs for the machine to boot up, if compared with 10 secs for most of the solid-state drives and 20 secs for the 2nd gen Momentus XT. A similar gadget usually takes around 50 secs to boot when it runs on a regular fast hard drive. In overall performance, the latest drive also showed improvement as well as helped applications launch strikingly quicker, as opposed to a regular hard drive.

At the data transfer rate, the Seagate Laptop Thin SSHD 500GB did not perform well. When we utilized it as a secondary device in the laptop, it delivered only around 39 MB/s for writing speed. Compared to writing speed, its reading speed was much better at about 90 MB/s. It scored around 17 MB/s when used as the system’s major drive and performed both reading and writing at once. But it is meaningfully slower compared to previous models. Probably, this is because it spins just at 5,400 revolutions per minute, as opposed to 7,200rpm.


Logically, desktop drives are not the direct competition for Laptop 2.5″ solid-state drives. So, we have collected some of the best rivals for comparison.

Noise Levels 

We constructed a silent box to test the noise emitted by this Seagate Laptop Thin SSHD 500GB drive. The chamber is made of acoustic foam, and we placed the drive 4-inch away from our digital TES-52 sound meter. Noise levels are measured during a high-definition Tune test.

Power Consumption

Under loads, we tested power consumption with IOMeter’s workstation pattern chewing via 32 concurrent Input / Output requests. Amazingly, in an idle condition, the Thin SSHD uses more power than its Momentus XT kin, having higher spindle speeds.

Final Verdict

The Seagate Laptop Thin can deliver a noticeable enhancement in performance over typical laptop hard drives, and it is certainly more inexpensive than an ordinary solid-state drive but can still cost you more than a typical hard disk. The similarly priced WD Scorpio Blue 1Terabyte can cost you only 6p / gigabyte. So, if you need quicker boot times compared to a regular drive and are willing to pay more, the Seagate SSHD is the best choice.
