Why Persistent Storage Is A Good Thing

Windows Mobile Team Blog : Why Persistent Storage Is A Good Thing: "Here's a quick primer on why you want Persistent Storage on your Pocket PCs.

Persistent Storage (PS) on PocketPC is new for Windows Mobile 5.0. (All Smartphones since the original 2002 release have had PS.)

Previously, your user data (email, contacts, calendar, settings, apps you installed, etc) were stored in RAM. RAM has the advantage of being really fast, but the significant disadvantage of needing a constant source of power for it to hold its data. Leave your device unplugged for long enough, and you'll lose all your data. Fixing that was the primary reason for moving PocketPCs to Persistent Storage. "
