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 Sabrent Rocket 4 PLUS 2TB drive showed that it was capable of 5,243 MB/s read and 5,774 MB/s write speeds. We noticed about half a dozen severe frame drops on the write test, but the overall score was still most impressive.
The two drives that use the Phison E18 controller top this performance chart and have the highest write speeds that we have ever seen with AJA System Benchmark v12.5.
