Dynamically switching command types to a mass storage drive
Abstract:
A method, device, and system are disclosed. In one embodiment method begins by receiving a first new mass storage disk access request. The method then determines the total number of access requests to the mass storage disk received in a window of time. If the total number of requests received over the period of time is greater than or equal to a request threshold number then a request frequency counter is decremented. Otherwise, the counter is incremented. The method continues by generating a legacy advanced technology attachment (ATA)-type command for the first new access request when the counter is greater than or equal to a counter threshold number. Otherwise, the method generates a native command queue (NCQ)-type command for the first new access request.
