Sure, there are other ways of getting massive amounts of bytes onto the PS3. One can simply swap in a new internal 2.5" SATA into the system, or even just hook up any old USB hard drive with little hassle; however, the latter won't give the same transfer speed as an eSATA. From the looks of it, the PHE-01 also comes with an additional four USB ports. Still, there isn't much else we know about this product or if it is even commercially viable ... or real. Maybe it's a leaked prototype perhaps? While we ponder this, you can check out more images of it at Gemaga.
