Windows Phone 7 represents a radical leap in the way the filesystem is presented to the user compared to WinMo. No longer will the user be able to access the true, underlying filesystem in any direct way - the OS will abstract the file system to a single view of all files - making no distinction between files stored on internal flash, or removable storage, or even striped across both similar to RAID0. The file system functions as a Virtual Unified Storage system.

WP7 will support SD cards, but the functionality is different now. The user data is striped across the SD card and the internal storage. This results in functionality similar to RAID0 - if a member disk is pulled from the set, the entire set ceases to function. Similarly, in WP7, if an SD card is disconnected from a deployed device, the device will go into a "reduced functionality" mode - where you are only able to make emergency calls. Upon re-inserting the SD, the data is restored and the system functions normally as it would before the card was pulled. If the card or its data is not available (got corrupted, lost, eaten) - The phone must be "hard reset" to restore full functionality and all user data will be lost.

My guess is this was at least partly done as a method to lock down the security of marketplace apps, and making the whole WP more like the iOS.
