ssd-benchmark 1.0.0

Super Simple Disk Benchmark - benchmarks the writing performance of your disk.
ssd-benchmark-1.0.0 is not a library.

Super Simple Disk Benchmark

inspired by simple disk benchmark.

This tool has just one single purpose, it measures the writing performance of your hard disk on macOS and Linux. More precisely spoken of the disk under your CWD.

It used random data from /dev/random and writes first sequentially chunks of 4MB until a total 4GB is written. It measures writing time and throughput.

After that it writes this random data 8 times again on disk and measures the average writing times and throughput for this.

Quick Start


To install the ssd-benchmark tool, you just need to run

cargo install --force ssd-benchmark

(--force just makes it update to the latest version if it's already installed)

to verify if the installation went through, you can run ssd-benchmark that should output similar to



$ ssd-benchmark
