Controlling ssd performance by the number of active memory dies

A method comprising:

• monitoring a number of active memory dies in a semiconductor storage device (an SSD) and monitoring a request queue of the SSD having a depth and comprising at least a first request, a second request, and an outgoing interval between the requests;
• and
• responsive to the outgoing interval being less than a target interval based on a target number of active memory dies and the number of active memory dies, setting an actual outgoing interval to be no less than the target interval and acting on the second request after expiration of the target interval.

A system comprising:

• a solid state device (SSD) and a host;
• and
• an interval throttling module stored in memory and implemented by a processor, the interval throttling module located in a data request completion path of the system and comprising a queue memory unit, a delay unit configured to delay acting on a second request if an outgoing interval between a first request and the second request is less than a target interval, and a calculator unit configured to dynamically adjust the target interval based on a number of active memory dies of the SSD.
