Massive 256 GB of storage capacity and a superb data transfer rate make this SDXC memory card ideal for recording HD video or photos with a demanding high pixel rate. The SDXC card is perfect for professional use at home or on the go. With 256 GB of storage, this SDXC card has plenty of room to record hours of HD video. The SDXC memory card has the exFAT file format and can store and transfer any size files. The SDXC memory card is the successor to the SDHC card.
The increasing use of high-quality video, high-resolution digital photography and mobile applications demands higher storage capacities and more demanding data transfer rates. The SDXC cards therefore offer a continuous minimum data transfer speed instead of a maximum speed.
Performance Classes:
Performance classes serve as the official unit for the speed measurement of SD cards and are defined by the SD Association. The unit is equivalent to 8 Mbps and measures the minimum write speeds based on the ''best possible fragmentation state in which no memory unit is occupied''.
Class 10: Guaranteed data transfer rate of at least 80 Mbps (10 MByte/s).
