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.

Cheers
Detlev
