microSDXC cards are able to handle significantly greater amounts of information due to two advances in technology. The exFAT file system enables the microSDXC card to handle large volumes of data while the UHS-1 interface can transfer videos and picture files with speeds of up to 104MB/sec* *microSDXC UHS-1 (Ultra High Speed Bus 1) memory cards can achieve the highest speeds only when paired with a UHS-1 device. For devices without the UHS-1 interface the guaranteed minimum data transfer rate for Class 10 will be 10MB/Sec. |
