We can be straight to the point when speaking about test results and the results we see are, as expected, very similar to one another. We see the throughput speed of 1800 MBit/s (225 MB/s) at full duplex for almost all of the models. The two Startech.com adapters with USB Type-C connection: the US1GC30W and the US1GC301AU2R, are somewhat behind the rest with measured speeds of 1200 MBit/s. The reason for this is not clear, but it could have something to do with the bridge chip used. The transfer speeds of 150 MB/s are not bad either way. You will still be able to manage your NAS and take advantage of a good fibre connection properly.
