Secure Digital Cards with High Capacity
Plenty of storage space at fast speeds, that's what Secure Digital High Capacity
(SDHC) cards have to offer. Starting from a capacity of 4 GB, the SDHC cards
are divided into several classes: 2, 4 and 6. Those values indicate the write
speed of an SDHC card (at a constant data rate). Class 4 for example means
a write speed of 4 MB/s.
