SSD Seagate Fast SSD (STCM1000400): express review of external SSD with USB Type-C SSD

External SSD drive-a faithful companion photographer or videographer, in General, all who need to carry large amounts of data. Today, these devices are already quite compact, silent, work with laptops and smartphones, and the USB 3.1 Gen2 interface with the Type-C port gives a speed of about 540 MB/s when reading.

We got to test the 1-Terabyte version of the drive Seagate Fast SSD. These are the most compact of Seagate’s external drives, available only in black and gray, compatible with PC and Mac, and factory-formatted to ExFAT, although you can reformat them to NTFS. Included with the drive are cables with ports Type-C and traditional Type-A.

From the characteristics in addition to the speed 500 - 540 MB/sec manufacturer more than anything, not promises, and even disassembled the drive to see his insides, does not work. There is no information about the SSD resource anywhere, but since modern 3D TLC chips allow you to create 1-terabyte drives with a resource of about 500 TBW, we can safely say that in this regard, Seagate Fast SSD, like other external drives, is eternal. The drive uses memory chips Toshiba 3D TLC, the Phison S10 controller and USB Converter on the chip ASMedia ASM235CM.

Seagate has its own Toolkit program to work with an SSD drive, but it is useless in terms of functionality, so you can not even waste time downloading. We go directly to the tests.

Test bench configuration:

  • AMD Ryzen 5 1600 @ 4 GHz
  • 16 GB DDR 4 @ 3 GHz
  • ASRock X470 Ultimate Taichi
  • Windows 10 x64 Enterprise
  • IoMeter (use custom patterns. Each test lasts 5 minutes, between tests-5 minutes of downtime to initialize TRIM. The diagrams show the instantaneous speed in each second of the test).

We start with a useless, but beautiful test CrystalDisk Benchmark and see very good results even with a 32-Gigabyte file size.

But fabulous 540 MB/s writing breaking on the harsh reality as soon as you copy to disk movie: 340-350 MB/s ceiling with ExFAT, and NTFS.

Naturally, most of the buyers of such external SSDS never think about the fact that the disk can be formatted in NTFS and get support for the TRIM function, which will always give you the best performance when writing. This is why we run our core test Suite twice: on ExFAT by default and on NTFS with a sector size of 4 KB.

In general, we see that the ceiling of sequential I/o operations is somewhere in the area of 500 MB/s, but only for the NTFS file system. By default, the recording speed can be as terrible as your imagination allows.

Random access shows that the basis of the portable drive is a full desktop SSD, and even very good for its class.

Stability test shows that you can use Seagate Fast SSD for constantly updated data. For example, to record logs or video surveillance files, well, or torrents. But enough synthetics, let’s move on to Real-world patterns. I once wondered how fast storage is needed to work with multimedia editors, and you can read the results of the research in this article. Based on this, we do not believe that the Real-world patterns test will show the real performance of your Photoshop or Premiere on your computer. Hardly a computer will even understand the difference between SSD and HDD, so take the following diagrams as theoretical research.


The maximum temperature of electronics in a 30-minute recording test rises to 63 degrees Celsius. At the same time, the housing is almost not heated, and it does not hurt to hold the drive. Of the tests of our colleagues, it becomes clear that the maximum temperature Seagate Fast SSD is 67 degrees Celsius, after which the drive goes to throttle down the write speed to 100 MB/s. it Usually occurs after 20-30 minutes of constant recording. We decided to add a write stability test using the largest disk load: sequential recording in 2-megabyte blocks for 30 minutes.

During this test, 775 GB of data was recorded without stopping, and the stability can be characterized as excellent. If you have the room temperature around 25-26 degrees Celsius, the temperature throttle in Fast SSD Seagate 1 TB does not threaten you.


Seagate Fast SSD-it’s just a good solid drive, such as you want them to be. There is nothing special, no pronounced pros or cons, so this is the perfect candidate for the title of “bought and forgot.”

What we liked:

  • Speed
  • The czse is almost not heated at work
  • The warranty is not tied to the volume of the record

What did not like:

  • There is no information about reliability of drive
  • Weak Seagate Toolkit software
