Abstract
Embodiments herein relate to selecting an accelerated path based on a number of write requests and a sequential trend. One of an accelerated path and a cache path is selected between a host and a storage device based on at least one of a number of write requests and a sequential trend. The cache path connects the host to the storage device via a cache. The number of write requests is based on a total number of random and sequential write requests from a set of outstanding requests from the host to the storage device. The sequential trend is based on a percentage of sequential read and sequential write requests from the set of outstanding requests.
