> A super simple disk benchmark tool

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 and writes first sequentially chunks of 8MB until a total 1GB is written. It measures writing time and throughput.

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

## Demo

![demo](./docs/demo.gif)

## Quick Start

### Using the docker image

```sh
docker run --rm ghcr.io/sassman/ssd-benchmark-rs
```

### Install on linux

[![Get it from the Snap Store](https://snapcraft.io/static/images/badges/en/snap-store-black.svg)](https://snapcraft.io/ssd-benchmark)

```sh
sudo snap install ssd-benchmark
```

### Install with cargo

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

Total time                                 1894 ms
Min write time                              205 ms
Max write time                              401 ms
Range write time                            195 ms
Mean write time Ø                           236 ms
Standard deviation σ                         62 ms

Min write throughput                       2.49 GB/s
Max write throughput                       4.87 GB/s
Max write performance                       623 IOPS
Min write performance                       318 IOPS
Mean write performance                      565 IOPS

## Notes

1 MB = 1024 KB and 1 KB = 1024 B
IOPS = Throughput [B/s] / Block Size [B]
```

## Options

- `-d` or `--directory` to specify a directory to write to and meassure the performance
- `--block-size` to specify the block size in, like `--block-size 4k` or `--block-size 8m` (default is 8m)
