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 Kingston KC2500 1TB drive showed that it was capable of 3,059 MB/s read and 1,852 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 read performance on the KC2500 had it being the fastest NVMe SSD that we have ever tested that used a PCI 3.0 controller! That said the write speeds ended up being a little slower than we hopped for and put the KC2500 in the middle of the pack for write speeds.
