Abstract
The present invention couples a disk drive to a small computer system interface bus by means of two buffers connected between a buffer-in bus and a buffer-out bus to allow data to be read out from a first filled buffer onto the buffer-out bus, while simultaneously permitting a filling of the second buffer from the buffer-in bus. When the second buffer is full and the first buffer is empty, the second buffer may be read while the first buffer is again filled. Toggling between the two buffers continues until the required data transfer is complete.
