SD and SDHC differ in some material ways. SD uses byte-level addressing and is limited to a size of 2 GB. (The spec could theoretically support 4 GB, but is limited by spec to half that, possibly as a hedge against implementation errors.) SDHC uses sector-level addressing, lifting that limit to a theoretical 2 TB. SDHC and SDXC are identical at a protocol level. |
