Abstract
The present disclosure generally relates to recognizing a violation of an expected write amplification (WAF) rate and informing a host device of the violation so that the host device may take corrective action and ensure the data storage device does not reach end of life (EOL) earlier than expected. The host can provide the data storage device with an expected lifetime and may additionally provide a benchmark WAF rate. The data storage device compares the actual WAF rate to the benchmark WAF rate and notifies the host device of any violation where the actual WAF rate exceeds the benchmark WAF rate.
