The site says, “On June 5th, Data Robotics will change the way you think about storage forever”. RAID-style expandable storage at any point? It sounds too good to be true! As one who just filled my 500GB RAID1 setup (largely with recorded MCE TV programs) this product sounds like an ideal solution- automatic backup, mix and match HDD sizes, makes and models, and it will work with my Mac or PC. If this works as advertised, I may be sitting in a pool of storage soon.
