I’ve used pcloud for 7 years, it’s been very stable and i even use it for backups (700GB daily).

It’s the only solution I’ve been able to send at consistent 1Gbps speeds to (except when it’s many tiny files).

About encryption, you unlock it once per restart and it stays open. It’s not like you have to enter password every time you move a file..

(For the backups i use rClone with encryption)

Same here, happy pCloud user (unlimited plan) for 2 years now. I didn't get the encryption, but it goes on sale from time to time for $75 lifetime.

I encrypt all my files locally before sending so the encryption doesn't matter for me.

I use rclone with --transfers 32 (for smaller files) and it seems to work fine without throttling.

You’re right, pCloud is not a bad alternative! I remember being annoyed by the password prompt for the encryption feature, but another user here wrote that they only need it once after every restart, which seems fine to me now. Back when I tried it for the first time (2 years ago) I decided against it because the OneDrive migration was not fully working (many files were skipped and it wasn’t transparent which ones or what was the reason), and the support couldn’t help me figure out any viable solution to migrate all my files. Nowadays with the NAS the migration would have been easier, I suppose.
