The latest version comes with an important USB 3.0 Card Reader driver update which improves the system power usage when an SD card is inserted.

If this update hasn’t appeared yet in Windows Update, you can go ahead and check manually for that. This particular problem with the attached SD card has been known for quite a while, and it’s been affecting the Surface Pro 2, as well.
