A new higher performance nine pin serial interface provides a nearly four time increase in data transfers up to 10 MBytes per second. Secure Digital cards also feature a mechanical write protect switch to prevent accidental overwrites or erasure. Major improvements in electrostatic discharge tolerances add increased data protection. All of these improvements come with only a slight increase in card thickness and weight, which allow for higher storage capacities. Secure Digital cards retain MultiMediaCard's minimal power requirements, making them ideal in low power, small form factor applications including MP3 players, smart phones and digital camcorders. Secure Digital cards include a proprietary cryptographic security scheme for copyright enforcement, which entities with DRM interests consider a 'feature.' Increased physical memory space coupled with flash memory density improvements and die size reductions promise excellent card capacity increases in the near future. |
