The performance of a cloud disk depends on its capacity. You can improve the performance by adjusting its capacity till it reaches the ceiling. When the ceiling is reached, you can purchase extra performance to get even higher performance. Note that the extra performance is only available for enhanced SSD instances. For more information, see Enhanced SSD Performance.
