I think there are posts on this forum somewhere where folks have reported what drives they have tried in these devices.
My guess is that the maximum for these devices are 2tb drives. My guess would be that the bootloader and/or firmware aren’t set up for gpt partition tables which would leave you with the 2tb mbr limit. Some sata controllers also don’t like drives above 2tb which might affect this device though I doubt it. Any/all of the above may also not accept drives with 4k sectors.
