Abstract
An apparatus is described that includes a solid state drive having non volatile buffer memory and non volatile primary storage memory. The non volatile buffer memory is to store less bits per cell than the non volatile primary storage memory. The solid state drive includes a controller to flush the buffer in response to a buffer flush command received from a host. The controller is to cause the solid state drive to service read/write requests that are newly received from the host in between flushes of smaller portions of the buffer's content that are performed to service the buffer flush command.
