Though I cannot guarantee that specific model as I have not used it, I have tried over 6 different USB drives from various manufacturers with my WD boxes and they all have worked. If you can plug it into a PC and use it as an external drive, you can use it with your SMP. I have never looked at the list when buying an external drive, I just always assume a decent USB drive will work.
Unless someone chimes in and says it is not compatible for some reason, I would say your risk is very low of it not working
