What is SD?
SD stands for Secure Digital. It is a small format for data storage a little larger than a postage stamp. Also it is about 2mm thick. SD also is unique in it's capability to support data encryption gf information stored on it. Also, it uses a serial interface to read and write to the flash memory at 2 megabits per second so it's slower than CompactFlash. An additional feature of SD is the support for peripherals so look for peripherals like Bluetooth coming soon. As always, you need drivers to support these new peripherals.
SD Support in the Pocket PC 2002
SD is supported in many of the new Pocket PC 2002s. This support
includes SD for peripherals as well as encryption in terms of the hardware
capabilities. In terms of the Pocket PC 2002 operating system,
Microsoft did not implement a way for users to specify that data stored is
encrypted or not. From my discussions with Microsoft, all data is
stored unencrypted unless you use a 3rd party encryption program. I
suspect that the SD encryption may be available to developers however I
have not been able to confirm the API that is used. It may be
implemented in a vendor specific way. So if you need
encryption, make sure you contract your hardware OEM and confirm how they
are implementing encryption.
