Which type of memory card format supports a maximum of 32GB?

The Secure Digital High Capacity (SDHC) format is specifically designed to support memory capacities ranging from 4GB to a maximum of 32GB. This makes it suitable for a variety of devices that require larger storage capacities compared to the original Secure Digital (SD) cards, which support a maximum size of 2GB.

SDHC cards implement the same physical dimensions as standard SD cards, allowing them to fit in devices designed for SD cards, as long as those devices are compatible with the SDHC standard. The specification not only allows for greater storage space but also supports faster data transfer rates compared to older formats.

The other choices have different maximum capacities: the original Secure Digital (SD) can only support up to 2GB, while Secure Digital Extended Capacity (SDXC) cards can go beyond 32GB, with capacities reaching in the terabytes. MicroSD cards can be SD, SDHC, or SDXC formatted, but without specifying the format type, it is unclear whether it refers to a card that meets the criteria for the given question. Thus, SDHC is the accurate choice for identifying the card format with a maximum capacity of 32GB.
