Efficient utilization of turbo-write buffers

Abstract:

A method of shuffling turbo-write buffers of a universal flash storage system is described. The method includes periodically determining a performance index of each turbo-write buffer allocated to a unique logical unit number of the universal flash storage system. The method also includes shifting a position of at least two of the turbo-write buffers according to the performance index of each of the turbo-write buffers and a threshold performance level.
