Storage Options

Hi! Found this sub a few months ago, and am still learning! Just wanted some inputs on adding additional storage -

Current setup - 8GB Raspberry Pi 4B, connected to a 1TB SSD. This runs Arr apps, Nextcloud and PiHole.

I initially thought 1TB was more than I’d need on a Pi, but here I am :)

Options I’m considering - -2 or 4 Bay NAS (Expensive, not sure what a NAS would add honestly) -Some sort of HDD adaptor which can hold a couple of drives, and connect it to the Raspberry Pi (Not sure if the pi will see multiple drives, or if it’ll consider the whole thing as 1 combined storage) -I’ve seen the HP Microserver which seems to have 4 drive bays, and thought that could behave like a NAS. I don’t know if this is more powerful than the Pi I have. -Buy a HP Mini PC to replace the Pi and build a NAS out of the Pi.

The Pi is good, but is choppy when playing some 4K videos on Plex/Jellyfin while 1080p works fine - not sure if either of the HP options would be able to play 4K or if they’re worth spending additional money on.

I’d appreciate any inputs! I’m not in the US so my options are more limited. I presume the cheapest option would be to buy an 8-10TB Drive with an adapter and plug it into the Pi - but I’m wondering if I’ll run out of storage again

Thanks!
