Secure Digital (SD) card technology is a standard for storage and peripheral I/O expansion that is tailored for portable devices. SD cards provide a high data-transfer rate, low battery power consumption, and storage that is portable among various devices. SD cards use flash memory to implement non-volatile storage for both read\write and read-only data. Due to the non-volatile nature of flash media, a power source is not required to retain data stored on an SD card.
Note
The SD card driver stack for Windows Embedded CE supports MiniSD, MicroSD, and regular SD cards.
**** Applies to Windows Embedded CE 6.0 R2** **
Through the introduction of a new and enhanced SD bus implementation, the operating system now supports up to version 2.0 of the SD Card Physical Layer Specification. The Microsoft SD bus version 2.0 provides a faster and more reliable SD bus implementation. Two of the features offered by version 2.0 of the SD bus are SD high capacity card support and SD high speed mode support. For additional information on the new SD bus and the benefits it offers, refer to the topics in this section.
