I just don't think 1GB of ram is worth it. I'd like to decommission the
1GB ram systems we have running in the armhf network...

I've got an odroid-c2 as part of the funded boards for
reproducible-builds, but upstream support for u-boot and kernel are
quite a ways off, last I looked.

microSD is surely too slow.

eMMC might be fast enough, not sure how easy it is to find a 64-128GB

Many of the boards for the armhf build network use USB-to-SATA adapters
over USB2 or USB3, and a 128GB SSD, although typically leave 20-50%
unpartitioned to leave extra room for wear levelling, since these are
doing almost constant writes 24/7.
I have three pine64+ boards that I'd consider using, and mainline or
near-mainline support is coming along. I'm not sure if the lemaker hikey
will ever be good enough to use, but I have one and keep an eye on
Although, any of the boards I have access to I might want to use as part
of a "test armhf chroots on arm64 hardware" installation, to get similar
kernel variation to i386 on amd64 hardware (and also not to tax my
bandwidth limits by downloading packages for another architecture).
