Here you can setup where your persistent data should be stored. If you want to use Nextcloud, LXC or other IO intensive applications, don't put them on internal flash, but always use external storage. Also make sure that your data will fit on the new drive before switching.
Once you choose a drive, it will be formatted to Btrfs filesystem and on next reboot your /srv (directory where all IO intesive applications should reisde) will get moved to this new drive.
Device currently in use is mmcblk0p1 (rootfs).
