UHS-II on MY PASSPORT WIRELESS PRO?

Can you confirm me if the MY PASSPORT WIRELESS PRO is compatible with the new SDXC UHS-II Cards?

Thanks

I have a recently purchased SanDisk Extreme PRO 128GB UHS-II card that works fine (albeit slow) with a 4TB My Passport Wireless Pro. This card was used primarily for RAW photo storage during a recent trip to Paris and was filled + copied to the MPWP pretty much daily without issue.

Keep in mind that the extra UHS-II contacts are not physically present in a MPWP so the SD card connects in UHS-I mode. Regardless, I’ve found copy speeds from this card as well as several Extreme Pro UHS-I cards are in the neighborhood of ~29MB/sec which is well below the 60MB/s WD advertises and the speeds noted in some of the early 3rd party reviews. Not sure what WD has done with their firmware to slow things down. USB3 <> PC reads/writes fluctuate between ~105 and 110MB/sec so the physical disk drive is capable of faster transfers.
