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 LaCie Rugged SSD 1TB Portable SSD topped out at 992.84 MB/s read and 954.11 MB/s write. According to this drives press release at launch it is rated to deliver speeds of up to 950MB/s. The Amazon listing says 1,050 MB/s, but that might be a typo on the sales listing. 

Benchmark Results: When compared to the other leading portable SSDs on the market right now, the LaCie Rugged SSD did very well. 

Benchmark Results: With the queue depth lowered to just one the performance went down a bit and we topped out at 790.11 MB/s read and 843.09 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 LaCie Rugged SSD dropped back a bit on this test, but not by much! 

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 LaCie Rugged SSD 1TB external drive was capable of averaging 944 MB/s read and 878 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 LaCie Rugged SSD 1TB did really well on this benchmark as it is the fastest USB 3.1 Gen 2 portable SSD that we have ever tested!

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 LaCie Rugged SSD 1TB drive topped out at around 942 MB/s read and 877 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 42 read and 39 write it didn’t receive a passing mark as a result, but 40 FPS is still workable for most.
