Additional Storage?

I’m currently running umbrelOS 1.4.2 on a Raspberry Pi 5 (8GB RAM). My SSD storage is at 825GB of 983GB, 58.5GB left. Heavy hitters taking up my disk storage are a Bitcoin Node (838GB) and Electrs (59.3GB).

I was wondering the best way to upgrade my storage capacity, should I upgrade my 1TB SSD to something larger, or add an additional USB SSD?

The easyiest way is to get a bigger SSD, adding another SSD is way harder.
