This is an external hard drive made by BUFFALO, featuring a USB connection and a DC input terminal. - Brand: BUFFALO - Connection Terminal: USB - Power Terminal: DC Input Thank you for viewing. I used this for several years as a TV recording HD, but I am selling it as junk because it wouldn't connect to my new TV after I replaced it. The capacity isn't listed, so I don't know the exact amount, but it had a considerable recording capacity. The cord is also included.
