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 on the Lexar NB620 1TB drive showed that it was capable of 2,682 MB/s read and 2,553 MB/s write speeds.
The Lexar NM620 1TB did pretty good on the AJA System Benchmark v12.5 and finished in the middle of the pack. The write speed on the NM620 was 61% higher than what we saw on the NM610. There is a massive performance difference seen on this benchmark!
