I have a 2TB WD Portable SSD bought last year and the SanDisk Extreme 500GB Portable SSD. But i never touch them unless im using an Android. Ah NAS. It might be a better solution for the long term i guess.they you better use icloud then lol...but big size version like 200gb, 2tb is really not cheap
I may finally buy NAS, synology may has reasonable solution.
