Nominal host interface The advertised maximum host-link rate. This is not a file-transfer benchmark.

Host requirements Required interface and operating conditions. Using a faster host port does not upgrade the enclosure bridge. Formatting and file-system support are separate.	USB4 or the documented Thunderbolt host path is needed for the top link mode; legacy USB hosts can run at a lower rate.
