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 ADATA Swordfish 1TB drive showed that it was capable of 1,632 MB/s read and 1,175 MB/s write speeds. The write disk performance pattern showed that write performance was anything, but smooth and that performance was dropping below 600 MB/s on several occasions. The disk reads from the video playback also showed a handful of drops below 1 GB/s.
The performance drops the overall read/write performance on the ADATA Swordfish 1TB drive helped put it in the bottom of the performance chart against the nearly two dozen other SSDs that we have run on this test system.
