FIG. 2B is a schematic block diagram illustrating one embodiment 201 of a solid-state storage device controller 202 that includes a solid-state storage device 102 in accordance with the present invention. The solid-state storage device controller 202 may include a number of solid-state storage controllers 0-N 104a-n, each controlling solid-state storage 110. In the depicted embodiment, two solid-state controllers are shown: solid-state controller 0104a and solid-state storage controller N 104n, and each controls solid-state storage 110a-n. In the depicted embodiment, solid-state storage controller 0104a controls a data channel so that the attached solid-state storage 110a stores data. Solid-state storage controller N 104n controls an index metadata channel associated with the stored data and the associated solid-state storage 110n stores index metadata. In an alternate embodiment, the solid-state storage device controller 202 includes a single solid-state controller 104a with a single solid-state storage 110a. In another embodiment, there are a plurality of solid-state storage controllers 104a-n and associated solid-state storage 110a-n. In one embodiment, one or more solid state controllers 104a-104n−1, coupled to their associated solid-state storage 110a-110n−1, control data while at least one solid-state storage controller 104n, coupled to its associated solid-state storage 110n, controls index metadata.
