Samsung 64GB Memory Card Pro microSDXC UHS-I Class 10 Grade 1 MB-MG64D / EU (Accessory)
I buy the sd card (not yet received) for my xperia z 2 to film in full HD at 60 fps and play mkv format film. from what I read, the flows are of high quality and I currently have a sd card 16gb class 10 in Samsung, which does not cause me any problem
