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 Crucial P5 1TB drive was shown to average 2,896 MB/s read and 2,744 MB/s write. The write disk performance pattern repeated itself nicely and had some spikes that slowed below 1.5 GB/s regularly. The disk reads were pretty smooth, but we did notice to spikes where the performance went from over 3 GB/s down to under 1.5 GB/s during the test.
Despite the performance drops the overall read/write performance on the Crucial P5 1TB SSD put it in the top 5 drives in our performance charts for the very first time.
