Verbatim SDHC (Secure Digital High Capacity, SD 2.0) Cards are designed to be used in compatible digital cameras, portable music players, camcorders, smart phones, PC's or other consumer applications. SDHC Cards use a FAT32file system, a specification that was established for applications with higher capacity needs and are especially suitable for high-quality video.

The increasing use of high-definition video, high-resolution digital photography and mobile applications demands higher storage capacity and more demanding data transfer rates. Because of this, SDHC cards guarantee a minimum sustained data transfer speed, not a maximum speed.

Verbatim SDHC Cards are fully compliant with all applicable SD standards. They also contain a write protect feature to prevent accidental erasure. SDHC cards use the same physical format as SD cards but cannot be used with SD host devices that do not comply with SDA Specifications Version 2.0.

SDHC logo is a trademark.

Speed Class Rating:
The speed class rating is the official unit of speed measurement for SD Cards defined by the SD Association. It is equal to 8 MBit/s, and it measures the minimum write speeds based on "the best fragmented state where no memory unit is occupied".

Class 10: Guaranteed minimum data transfer rate of 80 Mbit/s (10 MByte/s).


*GB = 1 billion bytes. Capacity available for storage will be less; device uses up to 10% of memory for formatting and other functions.
