Abstract
Example implementations described herein are related to methods for dynamically throttling host commands (up or down) to disk drives that include cache memory and rotating media, based on environmental conditions and/or drain rate from the cache memory to the rotating media, to provide consistent throughput for extended periods of time, and to avoid dramatic swings in performance from the pre-saturation state to the post-saturation state. The example implementations may be further extended to dynamically throttling host commands to devices that have HDD and SSD portions.
