Download Software from: https://downloadcenter.intel.com/download/30162?v=t
Preparation
1: Install "Intel® Memory and Storage Tool" at target system.
2: Install the unit in valid configuration, i.e. the application shall running valid use case, if possible use worst
case scenario (with respect to disk activity).
3: Before start of measurement, check and store actual SMART data.
- Start "Intel® Solid-Sate Drive toolbol".
- Refresh (button at home screen).
- Export SMART data, store current data at file (button at home screen).
Measurement
1: Check and save time for start test scenario.
2: Execute the test scenario long enough to cover all valid use cases which may affect disk activity.
(Recommended measurement period is at least 1 week without interruption).
3: When the measurement is completed...
- Check and save time for completion of the test scenario.
- Start Intel® Solid-Sate Drive toolbox.
- Refresh (button at home screen).
- Export SMART data, store current data at file (button at home screen).
Calculation
1: Calculate number of written bytes during the measurement period, use E1 or F1 parameter (stored log file).
Number of written bytes per second = (
F1
compleation
-
F1
start
) / (
Time
completion
-
Time

)
2: Convert to bytes per year.
3: Calculate expected life time (see previous time, section "Step-by-Step Calculation").
