2015 Macbook Pro + SDXC UHS-II cards

[Hexley]

Does the 13-inch 2015 Macbook Pro's built-in card reader have the additional connectors for SDXC UHS-II cards?

These additional connectors allows for faster read/writes of 156 MB/s (half duplex) or 312 MB/s (full duplex).

You mean the bottom pads on the bottom, I doubt it.

That is standard bus speed

But there is also maximum speed

UHS-II cards with maximum speed include

Lexar 64GB Professional 2000x UHS-II U3 SDXC
300 MB/s read and 260 MB/s write

SanDisk 64GB ExtremePRO UHS-II SDXC Memory Card
280 MB/s read and 250 MB/s write

Does Apple support it? Any Mac SDXC built-in reader allows such speeds?

iMac Pro is UHS-II, while the regular iMacs have no mention of it. Maybe they will be updated if the Pro goes UHS-III.
