Abstract

A mass storage device having a storage medium on which digital signals can be stored. The mass storage device is coupleable to a computer through a high-speed serial bus. The high-speed serial bus has a latency and a signal transmission rate sufficient to enable transmission of digital signals between the mass storage device and the computer without interim storage of the digital signals in a buffer inside the mass storage device. The computer has a processor capable of processing the digital signals and the digital signals may be transmitted between the mass storage device and the computer without processing of the digital signals by a processor in the mass storage device.
