The time it takes for SecuWipe to complete a wipe is not dependent on what type of data exists on the device or memory card. For example, an empty memory card will wipe at the same speed as a card completely full of data. A pass of writing random characters will take more time as each character must be individually generated.
The following table provides estimated wiping times depending on the algorithm chosen:
Platform: Windows Mobile 6.0 Professional
CPU: SC32442-400MHz
Memory card: MicroSD Kingston 2GB
