It's always save to backup whenever you can ;) But internal memory seems like it's an eMMC, similar to an internal SD card. Here are more usb and storage details: http://www.reddit.com/r/wiiu/comments/2mi5i8/is_the_wii_us_internal_memory_faster_than_usb/ |
To add to that I think that most the consumer level commercial flash available in the wide variety of USB flash sticks on the market are not built to the same standards as the Wii U's eMMC.
Below are some cut and paste details from the Samsung general press releases for the eMMC components that the Wii U uses (KLM8G2FE3B 8GB and KLMBG4GE4A 32GB):
"The eMMC architecture for embedded memory devices contains not only a data storage element (such as NAND flash memory), but also the controller for the storage element integrated on the same silicon die. Flash memory is often used for data storage, and is commonly controlled by a dedicated controller that operates under the application’s CPU and supervises data reads and writes. However, rapidly increasing memory densities are resulting in memory chips with ever-increasing capacities, making it difficult to keep the controller and memory on separate dies. The eMMC architecture allows devices and applications to maintain the required data rates and throughputs for high-density chips.
The eMMC solution consists of three components – the MMC (multimedia card) interface, the flash memory, and the flash memory controller – and is offered in the industry-standard BGA (ball grid array) package. eMMC is capable of operating at significantly high interface speeds, and provides the designer the flexibility to select the data transfer bus widths and interface voltages. eMMC is extensively used for platforms that require high levels of performance in very small form factors." - source
