Abstract: A solid-state cache memory subsystem configured to be used in conjunction with disk drives (26) for prestaging of data in advance of its being called for by a host computer (10). Buffer controller (32) is used for establishing and maintaining precise correspondence between storage locations in the solid-state array (34) and on the disk memory. The correspondence is used for establishing a reoriented position on a disk in the event of error detection, and in order to determine when a predetermined quantity of data has been read from the disk into the cache in a staging operation.
