Abstract:
1. A method of controlling a storage device, comprising: calculating, in a controller of the storage device, data throughput of the storage device in a current period; comparing, in the controller, the data throughput to a reference value; and adjusting, with the controller, an operation performance of the storage device in a next period based on the comparison and a delay factor of the current period, wherein the delay factor of the current period is computed in the current period by adding a value to a delay factor of a period prior the current period, the value being determined by subtracting a turning time where data throughput of the storage device in the current period exceeds the reference value from an end time of the current period and dividing this number by a number of requests made from a start time of the current period to the turning time of the current period.
