Hi, i am interested in buying the I3 Surface Pro 3. Due to the 64GB SSD i want to use a Micro SD for storage. I will use one of the very fast Micro SDs (Sandisk Extreme Pro or Lexar High Performance for example). I am not sure if the micro SD reader in the Surface Pro 3 is able to reach the highest transfer rates. Is anyone able to do some benchmarks with a 633x UHS micro SD with 64GB? That would be nice!
