Recognition and report of expected write amplification violation

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller is configured to:
• receive an expected write amplification factor (WAF) rate from a host device;
• calculate an actual WAF rate;
• determine the actual WAF rate is greater than the expected WAF rate;
• inform the host device that the actual WAF rate is greater than the expected WAF rate;
• receive an updated lifetime value and corrective action from the host device;
• implement the corrective action;
• and
• calculate a new WAF.

A data storage device, comprising:

• memory means;
• a controller coupled to the memory means, wherein the controller is configured to:
• determine a violation of a write amplification factor (WAF) rate, wherein the WAF rate is based upon determining an actual WAF rate is greater than an estimated WAF rate provided by a host device;
• inform the host device of the violation;
• receive an updated lifetime value and corrective action from the host device;
• implement the corrective action;
• and
• calculate a new WAF.
