External Storage App. [Manual](https://docs.nextcloud.com/server/28/go.php?to=admin-external-storage)
Set `userLocalMount` to automatically add a local directory as an external storage.
Use this option if you want to store user data in another folder or another hard drive
altogether.
In the `directory` option, you can use either `$user` and/or `$home` which will be
replaced by the user's name and home directory.
Recommended use of this option is to have the Nextcloud's `dataDir` on a SSD and the
`userLocalRooDirectory` on a HDD. Indeed, a SSD is much quicker than a spinning hard
drive, which is well suited for randomly accessing small files like thumbnails. On the
other side, a spinning hard drive can store more data which is well suited for storing
user data.
