Abstract: Embodiments herein relate to sending a request to a storage device based on a moving average. A threshold is determined based on a storage device type and a bandwidth of a cache bus connecting a cache to a controller. The moving average of throughput is measured between the storage device and a host. The request of the host to access the storage device is sent directly to the storage device, if the moving average is equal to the threshold.
