They're a hardware test site AFAIK, but I don't think anyone would actually buy 9 of them in reality though so what's the point. It's definitely all about the eWang. "You can purchase a 16GB Mobi Drive for $397, and this 32GB capacity drive that we are currently reviewing can be had for the same price as our 16GB Mtron Pro ($799) drive, but with double the capacity. Why such a large price difference between the Pro 16GB drive ($799) and the Mobi 16GB Drive ($379)?" So there we go, looking at about $800 for a 32GB drive. "The Mtron Mobi only has a three year manufacturer warranty that is automatically void if you are caught using these drives in an enterprise/server setup. While the Mtron Professional line has a full 5 year manufacturer warranty completely valid in the enterprise market. The only characteristic difference is that the Mtron Pro is rated at 120 MB/s read, 90 MB/s write, and the Mtron Mobi is rated at 100 MB/s read, and 80 MB/s write." Three year warranty for the Mobi, and 5 years for the Professional, so pretty standard shelf life really.
