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 Gold P31 1TB drive showed that it was capable of 2,881 MB/s read and 3,177 MB/s write speeds. The 500GB drive wasn’t too far off from these numbers, but when you look at the extended write tests results you can see that the write performance was dipped down under 800 MB/s. The 1TB drive had a handful of dips under 1.6 GB/s, but it wasn’t a constant pattern like on the 500GB model.
These results has the SK hynix Gold P31 being the second fastest PCIe 3.0 drive of the test group. Very impressive!
