1. A method of operation of a storage system comprising:
- at the storage system, receiving a host command from a host system, the host command comprising a write command;
at the storage system, in response to the host command, reading a current value of electrical power drawn by the storage system; and
at the storage system, in accordance with the current value of the electrical power drawn by the storage system, adjusting a bus speed for controlling a data transfer rate of one or more channels coupling a memory controller of the storage system to non-volatile memory devices of the storage system.

Abstract
A storage control system, and a method of operation thereof, including: a host interface unit for receiving a host command from a host system; a power measurement hardware, coupled to the host interface unit, for reading a current value of electrical power supplied by the host system in response to the host command; and a power monitor controller, coupled to the power measurement hardware, for adjusting a bus speed for controlling data transfer through a channel shared by a number of non-volatile memory devices, the bus speed is adjusted based on the current value of the electrical power.
