# Super Simple Disk Benchmark

inspired by [simple disk benchmark][1].

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 [`rand crate`][3] and writes first sequentially chunks of 8MB until a total 1GB 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

### Install

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

```bash
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

```sh
$HOME/.cargo/bin/ssd-benchmark
```

### Usage

```sh
$ ssd-benchmark
  ____    ____    ____                ____                          _                                  _
