What is SDHC?
SDHC (Secure Digital High Capacity) is a type of removable flash memory card that is an outgrowth of the SD (Secure Digital) format. SDHC cards have the same form factor as SD cards, although they can store much more data – up to 32 GB. SDHC cards come in a variety of capacities and speed classes. A speed class refers to how quickly data can be written to the card. The E-P1 can support SD and SDHC media up to 16 GB. Cards must have a minimum speed class of 6 in order to record movies with the E-P1.
