The present disclosure generally relates to ensuring a data storage device consumes as little power as possible. Different HW modules in the data storage device can operate at different frequencies to ensure any bottleneck HW modules operate at as fast a frequency as possible, while non-bottleneck HW modules operate at slower frequencies and hence, consume less power. The frequency for each HW modules is dynamic and is adjusted based upon detected bottlenecks so that the data storage device can operate as efficiently as possible and consume as little power as possible.
