# Mac - Disk IO speed test
|
|
|
|
Bash script for Mac OS X test SSD/HDD/SDHC or network storage's read and write speeds of devices on or connected to your mac.
|
|
|
|
Usage:
|
|
```
|
|
$ bash storage_speedtest.sh /Volumes/Data/
|
|
```
|
|
i.e., use: `/Volumes/Data` and not `/dev/disk2`
|
|
|
|
|
|
Note: administrator password is necessary for sudo to reset file system cache (using sync & purge command). This is because the Read speed results are incorrect when performed without a cache reset.
