By the next revision of the specification (UHS-II), SD will offer interface speeds of 156 & 312 MB/s, reaching parity with the SATA 1 & 2 specs you mention. The current UHS-1 specification already supports 104 MB/s, which is not that far off, especially from SATA I. I think a key reason that "real" SSDs are faster than SD in practice is that a real SSD operates a bunch of flash chips in parallel. In fact, that's a difference between high-end and low-end SSDs of the same capacity and physical size--the teardown photos usually show more chips on the high-end SSD. So you're not going to get full SSD performance at CF size, let alone SD size. (Plus there's heat and power concerns as P.J. points out.) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
