Misleading - You can only get the claimed 170MB/s read speed with a Sandisk UHS-1 USB Card Reader as it utilizes proprietary technology to go above UHS-1 speeds.
With a Delkin USB 3.0 Multi-Card reader that supports UHS-II; this card gets 92MB/s read and 84MB/s write. With my Surface Book 2 built-in SD card slot, this card gets 98MB/s read and 75MB/s write
