USB Drive Recommendations and Compatibility
While our system does not require a particular type of USB drive, some USB drives will not work because of how they are formatted.
There are a handful of USB drive models that we have tested and recommend to customers. We selected them because they work with our system, have reputable manufacturers, and can be bought at a reasonable price. You don't need more than 8GB in size, but for most of our recommended models the minimum you can buy is 16GB.
