An apparatus, system, and method are disclosed for satisfying storage requests while destaging cached data. A monitor module samples a destage rate for a nonvolatile solid-state cache, a total cache write rate for the cache, and a dirtied data rate. The dirtied data rate comprises a rate at which write operations increase an amount of dirty data in the cache. A target module determines a target cache write rate for the cache based on the destage rate, the total cache write rate, and the dirtied data rate to target a destage write ratio. The destage write ratio comprises a predetermined ratio between the dirtied data rate and the destage rate. A rate enforcement module enforces the target cache write rate such that the total cache write rate satisfies the target cache write rate.
