In my personal experience, "robust" and "usb" do not mix well in one sentence. Maybe I'm somewhat conservative, but just in another product I have seen spurious USB dis- and reconnects after days and weeks of otherwise solid functioning. Of course they _did_ mess up the software and crash the system. So be sure that your software stack can cope with something like that. In effect, currently I would not try to design a "robust system" (ready to be sold as a product) with its primary rootfilesystem on a USB storage device. For IDE/ATA/SATA all the problems in a running system that I have seen have had their cause in the device, not in the interconnect method. This is not something I can say about USB.
