FAST EXECUTION OF FLUSH COMMANDS USING ADAPTIVE COMPACTION RATIO

A method includes receiving one or more storage commands and at least one flush command in a storage device, which includes a non-volatile memory and a volatile buffer for buffering data received for storage in the non-volatile memory. The flush command instructs the storage device to commit the data buffered in the volatile buffer to the non-volatile memory. The storage commands are executed in accordance with a first storage rule. The flush command is executed in accordance with a second storage rule having smaller latency relative to the first storage rule.
