I'm looking for a budget friendly way to store a couple TB of data on a small device (USB ?)

Hello

What budget friendly solution would you recommend for someone that wants to store at most 1-2TB of data on a portable device ?

I'm curently using 256Gb USB keys, but it's getting annoying to swap between them when I need to update the storage or retrieve something.

I went with USB because it was cheaper and less prone to failure by being handled, but I don't know if it's the cheapest and most reliable way to store data I want to access semi-regularly.

What would be your advice ?

Thank you
