Examples of selective enablement of operating modes or features of a storage system via host transfer rate detection are disclosed. In one example implementation according to aspects of the present disclosure, a storage device includes an interface configured to couple the storage device to a computing host indirectly via an intermediate fabric; and a storage controller configured to determine whether a nominal data transfer rate of the interface across the intermediate fabric is at or above a predetermined threshold, and selectively enable coalescing of status information that is to be returned to the computing host via status combining across multiple host requests responsive to it being determined that the nominal data transfer rate is at or above the predetermined threshold.
