In the context of data storage, an approach to pre-fetching data prior to a read request involves receiving a read request and a next read request, and updating metadata corresponding to the read request with a next data storage address corresponding to the next read request. Responsive to again receiving the read request at a later time, the next data storage address can be read from the read request metadata and the next data can be pre-fetched from the next data storage address in advance of processing a following read request. Furthermore, the next data can be pre-fetched during read queue idle time and stored in a cache buffer, in anticipation of another incoming next read request, responsive to which the next data can be returned to the host from the buffer rather than from a read of non-volatile memory.
