GitHub CodeQL vs Illumine IT disk-benchmark

GitHub CodeQL has no write-up on Specifiction yet; its figures are above.

Illumine IT disk-benchmark is a lightweight console program for benchmarking hard drives, SSDs, SAN disks, HBAs, RAID adapters and storage controllers. It can test physical or virtual disks that are local or remote, using multiple threads to simulate concurrent reads and writes. Test options include random file sizes, random delays, write-only runs and configurable read and write buffer sizes. Results show read and write timings per thread and as averages, summary results, and CPU and wall time. Output can be reduced to values for spreadsheet use, and the program can print system I/O information to help set buffer sizes. Continuous runs can monitor cloud-drive QoS, disk replication and active/passive RAID swaps. The tool is free and described as an open-source C command-line program. Listed platforms are Linux and Windows; its broader supported-platform list also names POSIX and MS-DOS. Linux build instructions require GCC and list POSIX Threads as the only dependency. The README warns that continuous runs with many threads, large files and no delay can fill the tested disk and cause high CPU load.
