What you’re seeing here is one of the external hard drives for the PS3 from Buffalo, that is “officially licensed” by Sony. It is the HD-CL500U2/SC, and it is similar to the HD-AV2.0TU2.
Both of these have similar features of 500GB. The HD-CL500U2/SC costs about $130, and the HD-AV2.0TU2 costs about $170. They are planning to be released in Japan only next month, with no word of them coming to the states.
