SanDisk's Ultra SDXC Card is a 64GB Secure Digital portable memory card and is the first SDXC model that SanDisk is offering. It has a storage capacity of 64GB, twice that of the highest possible SDHC cards, and is SD Class 4 certified, guaranteeing sustained read/write speeds of 4.0MB/s. SanDisk also suggests that this card can reach sustained speeds of up to 15 MB/s. This card largely targets avid photographers who use DSLR cameras with high resolutions or multi-shot modes, as well as HD video recorders. It should be noted that currently not all devices are compatible with the SDXC format, and potential buyers should verify whether their device is compatible. This card has a high price point.
