Hello all, when I use mac or bootcamp win8.1, the sd card reader works well, but when I use pd10 win8.1, the performance drops remarkably, from 60m reading 15m writing to 30m reading 15m writing, any idea? Thank you so much! btw, the usb3.0 is already enabled for pd10 win8.1 This is normal bootcamp win8.1, pretty much the same under yosemite This is pd10 win8.1 with usb3.0 enabled, same sd card&reader
