Illumine IT disk-benchmark

What Illumine IT disk-benchmark is

Illumine IT disk-benchmark is a free command-line program for benchmarking storage such as hard drives, SSDs, SAN disks, HBAs, RAID adapters, and storage controllers. It can test physical or virtual disks, whether local or remote, using sequential tests. Multiple threads simulate concurrent reads and writes. Users can configure random file sizes and delays, choose write-only mode, and set read and write buffer sizes.

Results include read and write timings for each thread and averages, summary results, and CPU and wall time. Output can be limited to values for spreadsheet use, and the program can show system I/O information to help set buffer sizes. Continuous runs can monitor cloud-drive QoS, disk replication, and active/passive RAID swaps. Listed availability is Linux and Windows, while the broader supported-platform list also includes POSIX and MS-DOS. Linux build instructions require GCC and list POSIX Threads as the only dependency; the README describes a TDM-GCC Windows build and provides a 64-bit binary. The README warns that continuous tests with many threads, large files, and no delay can fill the tested disk and cause high CPU load.
