CrystalDiskMark 7.0.0h x64

CrystalDiskMark is a small benchmark utility for drives and enables rapid measurement of sequential and random read/write speeds. Note that CDM only supports Native Command Queuing (NCQ) with a queue depth of 32 (as noted) and shows the highest score of five runs.


Benchmark Results: The Seagate One Touch SSD 1TB drive is rated at up to 400 MB/s, but on our AMD X570 test system we were able to reach 449.98 MB/s read and 258.25 MB/s write! 

Seagate One Touch Portable SSD CrystalDiskMark Peak

Benchmark Results: When compared to other portable USB drives the Seagate One Touch 1TB comes in with the lowest speeds of any recent portable SSD that we have tested. 

Benchmark Results: With the queue depth lowered to just one the performance dropped down to 414.27 MB/s read and 252.91 MB/s write. This is is a bit more realistic than testing a portable drive at a queue depth of 8.

Seagate One Touch Portable SSD CrystalDiskMark Real

Benchmark Results: The Seagate One Touch 1TB  actually moved up one spot on this benchmark scenario as we sorted by write speed performance and it did better than the Samsung T5 500GB drive from 2017. 

AJA System Test

AJA System Test:

AJA System Test by AJA Video Systems measures system disk performance using video test files of different resolutions, sizes and codecs. We selected the standard 4K UltraHD resolution, a test file size of 1GB and the ProRes 4444 codec to see how this drive does with regard to video rendering performance. ProRes 4444 is used for heavy effects work and deep color projects. We changed the default test file size from 1GB to 16GB to better represent real-world usage. The results from this benchmark help content creators with regards to rendering expectations, throughput, file read/write expectations for transfers and that kind of thing.

Benchmark Results: The AJA System Test results had the Seagate One Touch 1TB drive topping out at 344 MB/s read and 239 MB/s write. The write disk performance pattern showed that write performance dipping below 70 MB/s during the long sustained write test, so the direct to NAND write speed is fairly low on this drive.

Benchmark Results: The One Touch 1TB drive managed to perform better than the HyperX Savage EXO 480GB and Samsung T5 500GB drives on this test. 

Blackmagic Disk Speed Test

Blackmagic Design has a storage drive benchmarking tool that customers can use to test the speed of your disk performance for working with high quality video at different resolutions and codecs.

Benchmark Results: The Seagate One Touch 1TB portable SSD topped out at around 392 MB/s read and 174 MB/s write on the Disk Speed Test by Blackmagic. The results show that most 720P and 1080P video content should be able to b e worked with on the One Touch. Moving up to 4K 60FPS proved to be too much for this drive in the Apple ProRes 422 HQ, Cinema DNG RAW and 10-bit YUV 4:2:2 video tests.
