In their own words
AJA System Test
AJA System Test evaluates drive performance so users can estimate whether a drive system can record and play back different resolutions and codecs. It measures read and write speed and overall throughput, including on network mapped drives. In its graphical interface, users select a test type, drive, video size, frame rate, file size, and connected video device. Results can appear in MB/sec or FPS with graphs. The report generator produces text results that users can copy into spreadsheets or other software, and result exports include text report, PDF, and SPX formats. Custom test profiles are supported. Workload areas also include PCIe bandwidth, AJA-device DMA, and combined disk and device I/O; PCIe bandwidth testing is part of the full version included in AJA Desktop Software downloads. The standalone Apple Store and Windows versions are listed as AJA System Test Lite v16.0 at free. The software runs on macOS and Windows, and AJA offers a download path that does not require signing up.
