The other day, a 1TB SSD turned up (Western Digital Green SN3000). I tried booting from NVMe but didn't notice much of a speed boost… however for storage of my personal data, NVMe is by far the safest place to keep it: if something destroys the compute module, my data is entombed on the eMMC unless I manage to successfully de-solder it and tack wires to the balls to interface to it.
It's also a better place for swap space. The NVMe should have better endurance and performance than the eMMC. I'll keep Debian on the eMMC (where the 64GB size is less of a constraint), `/home` and swap on NVMe.
I've set up a 180GB partition formatted BTRFS, and have Gentoo building inside that.
So far this machine this machine is taking Gentoo in its stride. I intend to get a bootloader going so I can comfortably dual-boot (maybe U-boot, GRUB or rEFInd?) but my journey into the ARM world is going fine so far.
