The RS-08 is a fixed-platter [[fixed-head disk]] drive that can store up to 262KW of data. It used 128 fixed read/write heads and recorded data on a single nickel-cobalt plated surface. The data transfer rate was 62.5K words per second (operating on 60 Hz power), or 52.083 words per second (on 50 Hz power).

Its controller is the [[RF08 disk controller]].
