The Superior Pro microSDXC UHS-I Card from Silicon Power is available with 64GB, 128GB, 256GB and 512GB capacities, each sporting a different color, since the series name, Colorful. This model was made to meet UHS Speed Class 3 and the UHS Video Speed Class 30 standards for 4K UHD video recording. In terms of speed rating, the card is noted to have up 100MB/s reads and up to 80MB/s writes; the speeds may differ depending on the device configuration as well.
