The 40Gbps port is indicative of Thunderbolt 3 speed. So just like the original HyperDrive Duo, this one has one USB-C port capable of delivering Thunderbolt 3 speeds (as long as you're using an appropriate Thunderbolt 3 cable and the device you're plugging in is also Thunderbolt 3-compatible) plus 100W of Power Delivery, and one USB-C port capable of delivering 5Gbps speeds (plus 60W of Power Delivery, which the first version did not support on this port). As for the USB-A ports, you need to understand that "USB 3.0" and "USB 3.1 gen 1" are basically synonymous. They mean the same thing. So whether it says 3.0 or 3.1 gen 1, it means that the ports are capable of 5Gbps (you don't get to the next speed tier, 10Gbps, unless you have USB 3.1 gen 2). Nothing has changed in that regard on the new version. The company that makes this device, Sanho, only markets the new version's USB-A ports as "5Gbps" on their website (they don't use 3.0 or 3.1 gen 1 terminology), so they basically remain unchanged. So, overall, the only real difference in the ports between the old and new versions of the HyperDrive Duo is that the 5Gbps USB-C port now can deliver up to 60W of power, and supposedly the HDMI port is capable of delivering up to 4K @ 60Hz instead of just 4K @ 30Hz (which was not my experience, however ... see my posted review).
