Wear Leveling: equal wear leveling of static and dynamic data
The wear leveling assures that dynamic data as well as static data is balanced evenly across the memory.
With that the maximum write endurance of the device is guaranteed.
Write Endurance: Due to advanced wear leveling an even use of the entire flash is guaranteed, regardless
how much “static” (OS) data is stored. Example: If the average file size is 10MByte and the total capacity is
8GByte, 48Mio write cycles can be performed.
