Surface 3 pro (i5 / 256 gb) sandisk microsdxc 128 gb not working properly i just bought a sandisk ultra microsdxc uhs-1. i have not been successful getting this card to work consistently and reliably.. From the description: professional ultra sandisk 64gb microsdxc microsoft surface pro 3 card is custom formatted for high speed, lossless recording! includes standard sd adapter. (uhs-1 class 10 certified 30mb/sec).. Remember that the surface 3 has a microsdxc card slot, not a standard sdxc card slot. right now capacities are limited to 128gb as that is the largest sized microsdxc card you can currently purchase. sandisk is coming out with a 200gb card in the future that should work with devices that are compatible with 128gb cards..
Microsoft surface pro 4 . manufacturer: microsoft surface pro 4 : device type: tablet : sandisk recommends. sandisk ultra
