Data from storage devices is stored in a read cache, having a read cache size, and a write cache, having a write cache size. The read cache and the write cache are separate caches. Cache configuration of the read cache and the write cache are automatically and dynamically adjusted based, at least in part, upon cache performance parameters. Cache performance parameters include one or more of preference scores, frequency of read and write operations, read and write performance of a storage device, localization information, and contiguous read and write performance. Dynamic cache configuration includes one or more of adjusting read cache size and/or write cache size and adjusting read cache block size and/or write cache block size. |
