Flash Endurance and Wear Agent: what goes in, what the agent does and what you get

What it does

A device that logs every second can wear out its flash in two years instead of ten. This agent reads write logs from test runs and counts the writes to each sector, then estimates writes per day for each sector at expected field use. It compares them with the rated endurance of the flash part, including the drop at high temperature, and calculates the projected life. For sectors that will wear out too soon, it proposes changes such as wear leveling, write batching or a change to the log interval. After the change is built and tested, it measures again and compares the new projection. The engineer approves the change. Edge case: a settings sector written only at setup is ignored, to avoid noise in the report.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

A sector is at risk when projected life is under the required life with a 2 times safety factor. Fixes are chosen by how much they reduce writes.

  • Require a 2 times safety factor on projected life
  • Derate endurance at the maximum field temperature
  • Ignore sectors written only at setup or update
  • Prefer write batching before larger redesigns

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Required product life in years
  • Safety factor (default 2)
  • Flash part endurance values
  • Temperature range for derating

What keeps you in control

It always asks you first

  • Adopting a wear-reduction change in firmware

Hard limits

  • Never changes the firmware itself
  • States the data loss risk for any batching change

It stops when

  • Done: all sectors meet the life target
  • Stop: logs lack per-sector detail

An example run

What happensA 10-year life target was set. The log sector, written 86,400 times a day, projected to 2.3 years against a rating of 100,000 cycles, which failed the check. The agent proposed batching 60 entries into one write. The retest showed 1,440 writes a day and 190 years of projected life before derating. The engineer approved batching, with a 15-minute data loss window accepted.
