@EpicKitty I currently have a single Dell Mini PC with Proxmox on it, an inactive larger server that was made from parts of my old gaming PC, the Pi 4 running this instance, and a random Thinkpad from ~12 years ago that isn't really being used
one thing I'll give ext4 credit for that other FSes don't have is that it records mow much writes were made to the partition over its lifetime, something that is especially useful for certain storage devices without any sort of built in record of lifetime writes cough cough SD cards
