SSD Benchmark

What SSD Benchmark is

SSD Benchmark is a free command-line utility for measuring disk write performance. It writes random 8 MB chunks sequentially until 1 GB has been written, repeats that workload for eight cycles, and records timing and throughput. Results include write throughput, IOPS, and minimum, maximum, mean, and standard deviation for cycle times. By default, it tests the disk associated with the current working directory; the -d or --directory option selects another location. The --block-size option changes the chunk size from the documented 8 MB default. The project lists Linux, macOS, and Windows support, with binaries for Apple Silicon and Intel macOS, ARM64 and x64 Windows, and ARM64 and x64 MUSL Linux. Installation methods include Docker, Homebrew, Snap, and Cargo. The public repository identifies a GPL-3.0 license. Its purpose is deliberately narrow: sequential write testing rather than random I/O testing.
