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 G-Technology ArmorLock 2TB Portable SSD topped out at 1024.91 MB/s read and 942.69 MB/s write. According to this drives press release at launch it is rated to deliver speeds of up to 1000 MB/s and we are able to exceed that on the sequential read testing on CrystalDiskMark. 

Benchmark Results: When compared to the other leading portable SSDs on the market right now, the ArmorLock is one of the fastest that we have tested to date. 

Benchmark Results: With the queue depth lowered to just one the performance went down a bit and we topped out at 815.04 MB/s read and 860.33 MB/s write. This is is a bit more realistic than testing a portable drive at a queue depth of 8.

Benchmark Results: Almost all of the drives get less performance at QD1 and this is expected. The G-Technology ArmorLock 2TB SSD barely went down on this benchmark and remained in second place with 815 MB/s read and 860 MB/s write sequential write speeds. 

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 showed the ArmorLock 2TB external drive was capable of averaging 929 MB/s read and 874 MB/s write. The capture and playback was fairly smooth as performance as you can see in the performance over time charts shown in the results above.

Benchmark Results: The G-Technology ArmorLock 2TB did really well on this benchmark as it is has the second fastest write speeds of any portable SSD that we have ever tested on AJA System 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 ArmorLock 2TB drive topped out at around 920 MB/s read and 873 MB/s write on the Disk Speed Test by Blackmagic. The results show this drive will handle all 1080P and 2K content just fine, and most 4K content. The frames on 4K 10-bit YUV 4:2:2 video were 41 read and 39 write it didn’t receive a passing mark as a result, but ~40 FPS is still workable for most.
