It is recommended that the actual storage location of AppData and other directories (Downloads Gallery Media) can be set separately after the storage is merged.
Store AppData separately to SSD (or on a specific hard disk) and set other directories to the merged location on the mechanical hard disk to reduce unnecessary mechanical hard disk operation, reading and writing.
我当前的设置：
> admin@casaos:~$ df -hl
> Filesystem Size Used Avail Use% Mounted on
> tmpfs 1.2G 3.1M 1.2G 1% /run
> /dev/sdb2 111G 8.3G 101G 8% /
> tmpfs 5.7G 0 5.7G 0% /dev/shm
> tmpfs 5.0M 0 5.0M 0% /run/lock
> /dev/sdb1 1.1G 6.1M 1.1G 1% /boot/efi
> tmpfs 1.2G 4.0K 1.2G 1% /run/user/1000
> /dev/sda1 916G 12K 907G 1% /mnt/Storage1
> /dev/sdc1 2.7T 11G 2.7T 1% /mnt/Storage2
> /dev/sdd1 916G 12K 907G 1% /mnt/Storage3
> /var/lib/casaos/files 111G 8.3G 101G 8% /DATA
其中sdb为ssd，其他为机械硬盘
当使用合并存储后：
> admin@casaos:~$ df -h
> Filesystem Size Used Avail Use% Mounted on
> tmpfs 1.2G 3.6M 1.2G 1% /run
> /dev/sdb2 111G 8.3G 101G 8% /
> tmpfs 5.7G 0 5.7G 0% /dev/shm
> tmpfs 5.0M 0 5.0M 0% /run/lock
> /dev/sdb1 1.1G 6.1M 1.1G 1% /boot/efi
> tmpfs 1.2G 4.0K 1.2G 1% /run/user/1000
> /dev/sda1 916G 12K 907G 1% /mnt/Storage1
> /dev/sdc1 2.7T 11G 2.7T 1% /mnt/Storage2
> /dev/sdd1 916G 12K 907G 1% /mnt/Storage3
> /var/lib/casaos/files:/mnt/Storage1:/mnt/Storage2:/mnt/Storage3 4.6T 19G 4.6T 1% /DATA
此时，docker程序的config数据存储于/DATA/AppData，实际会有数据存储到机械硬盘上，如下：
> admin@casaos:/mnt/Storage2/AppData$ ls -al
> total 32
> drwxrwxrwx 8 root root 4096 Jun 21 08:53 .
> drwxr-xr-x 7 root root 4096 Jun 21 07:11 ..
> drwxr-xr-x 3 root root 4096 Jun 21 04:17 Jackett
> drwxr-xr-x 3 root root 4096 Jun 21 08:53 Jellyfin
> drwxr-xr-x 3 root root 4096 Jun 21 03:12 Nextcloud
> drwxr-xr-x 3 root root 4096 Jun 21 03:08 PhotoPrism
> drwxr-xr-x 3 root root 4096 Jun 21 03:07 qBittorrent
> drwxr-xr-x 3 root root 4096 Jun 21 03:28 Syncthing
> admin@casaos:/mnt/Storage2/AppData$
建议在合并存储后，可单独设置AppData和其他目录（Downloads Gallery Media）的实际存储位置。
将AppData单独存储至SSD（或特定硬盘上），将其它目录设置到机械硬盘的合并位置上，减少不必要的机械硬盘运行、读写。
