Unfortunately I don't have the spare 8 TB. Been unemployed for 6 months, have not gotten a single offer in that time, + memory/storage crisis, etc. Shit's fucked.
I don't think I would downgrade though. I just hope this gets fixed someday... I can deal with the terrible memory bandwidth but I don't like to reboot.
(That said, macOS is so, so much better at reboots than Windows)
