Is there a USB 3 / eSata solution for the 4.1 Mac Pro on Mavericks that "Just Works"?

I've been browsing the forum and everyone seemed to report either issues during computer sleep, compatibility issues with some external hard drives and RAIDs... But is there a solution that just works and well at that? Surely there must be something? I'd like to add USB 3 to my Mac Pro 2009 but eSATA would be nice too. I was considering this:

Is it any good? Perhaps there is a better solution out there?
Thanks guys!
