Abstract

Described embodiments provide a solid-state drive (SSD) including a media controller and a solid-state media. A control processor of the media controller determines a logical address, a transfer size, and map data based on the logical address and transfer size, associated with a read request received from a host device. Based on the logical address and a sequential zone defined based on one or more previous read requests, the control processor determines whether the received read request is a sequential read. A map data pre-fetch size is adjusted based on the transfer size of the received read request and whether the received read request is a sequential read. A corresponding portion of the map data is transferred from the solid-state media to a map cache coupled to the control processor, the transferred portion having a size equal to the adjusted map data pre-fetch size.
