Forgive me if this answer is posted somewhere else, but I couldn't find it from searching.
I've decided to turn a a Raspberry Pi 4 (4gb model) into a low-power file and Plex server (will not be transcoding). I'll be attaching a couple of "old" hard drives to it via USB for the file storage. I still need to buy a microSD card though and was trying to figure out what size to go for.
Anyone have some recommendations for me? I know the OS is pretty small (I run it headless as well), though I'm concerned about where application databases are stored and run from (I'm assuming the SD card).
Any advice is greatly appreciated!
