    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
    https://www.sdcard.org/consumers/speed/bus_speed/index.html

    But there is also maximum speed
    https://www.sdcard.org/consumers/speed/max_speed/index.html

    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
    http://www.sandisk.com/products/memory-cards/sd/extremepro-sdxc-sdhc-uhs-ii/?capacity=64GB

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