DANE-ELEC'sSecure Digital range comprises cards with 128, 256, 512 MB, 1GB, 2GB, and 4GB of memory capacity.
Their rate of data-transfer varies between 2 and 4 MB per second. Compared to the Multi Media Card composed of 7 connexion pins, the Secure Digital card is composed of 9 connexion pins. This new organisation allows faster transfer of data while the memory card is on SD mode.
On the other hand, the Secure Digital has an integrated security mechanism, the CPRM Content Protection for Recorder Media which insures a high degree of protection and file-encryption. It controls the reading, copying, transfer or erase functions. In this way it becomes possible for the user to forbid or authorize the copy or to offer a reproduction right.
