Why not use an SD card as the system disk, booting OS + apps and reserve
the hdd for data?

The trick is to separate app installation, executables etc, from data. I
get that from using Docker containers. It's worth looking at Docker
because life is just so much easier, in the long run. Not only does
Docker separate exes and data it also tends to script setup/config
making changes easier.
