Adaptive management of intermediate storage
Storage devices that can perform adaptive management of intermediate storage memory, and methods for use therewith, are described herein. Such a storage device includes non-volatile memory, wherein a portion thereof is designated as intermediate storage (IS) memory and another portion thereof designated as main storage (MS) memory. The IS memory has lower write and read latencies, greater endurance, and lower storage density and capacity than the MS memory. In certain embodiments, a host activity pattern is predicted, a relocation schemes is selected based on the predicted host activity pattern, and the selected relocation scheme is executed to thereby selectively relocate one or more portions of the data from the IS memory to the MS memory in accordance with the selected relocation scheme. The relocation scheme that is selected and executed can change over time. Additionally relocation schemes can be generated based on activity log(s) and thereafter selected for execution.
