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 addlink X70 1TB drive showed that it was capable of 2,622 MB/s read and 2,852 MB/s write speeds. The write disk performance pattern showed that the write speeds at times was over 3 GB/s, but at other times was well under 1GB/s.
The results here had the addlink X70 1TB up in the top 5 for PCIe 3.0 x4 drives, which is solid! The only two PCIe 4.0 x4 drives in the chart have a firm grip on the top two spots and will only be dethroned when the first true PCIe 4.0 controllers arrive later in 2020.
