I think there are two evaluable options; dm-crypt with LUKS, and fscrypt.
For performance reasons, I recommend using Adiantum in both cases:

Thanks, I'll give it a try.

Is there a good summary of available options for Raspbian full-disk encryption for the Pi 4's SD card, and for any attached hard drives (e.g. for an NAS server)?

This is my cooling solution.

Thanks, that makes sense. (Video over VNC isn't something I was counting on being able to do, but I just wanted to make sure the sluggishness wasn't a sign that things were set up improperly.)

I have a 2GB RPi4B, full updated Raspbian, running headless via VNC with HD desktop resolution, VNC Viewer running on a PC. When I try to watch any full-screen HD YouTube video via Chromium on the Pi, I get a slideshow with about 2-4 fps. CPU goes up to 71C, load 6.6, frequency 1500MHz, memory use 4...

Update: it all went smoothly (including installing the new firmware).

Thanks. Yes, it was a clean install of Buster on the Pi 3 B+. My Pi 4 is coming in a couple of days, so I'll report how the transition goes.

If you're running Raspbian Buster on a Pi 3 B+, would it work to just move that SD card to a Pi 4 B, or would you have to reinstall Raspbian for the Pi 4?
