Comment vérifier la durée de vie d'un SSD ?

Hello Carl,

Thank you for posting your question on our forum.

To estimate your SSD’s lifespan, look at how much data has been written to it in total, the type of NAND flash it uses, and its endurance rating, usually given as TBW (terabytes written) or DWPD (drive writes per day).

1) Check Endurance Rating (TBW or DWPD):

This is specified by the manufacturer and indicates the total amount of data that can be written to the SSD before it is expected to start failing. For example, a 1TB SSD might have a TBW rating of 600TB.

2) Monitor Total Bytes Written (TBW) and SMART Data:

Use programs like Auslogics SSD Optimizer.

The program provides health monitoring and SMART data, showing how much data has been written, wear leveling count, media wearout indicator, and remaining lifespan estimates.

To find this information run SSD Optimizer and open the Drive Health tab.

3) Calculate Estimated Lifespan:

By tracking your average daily data writes (e.g., 10GB/day), you can estimate the SSD lifespan using this formula:

Lifespan in days = Manufacturer’s TBW / Daily data written

This gives a rough estimate under optimal conditions.

4) Interpret SMART Metrics:

Pay attention to indicators like media wearout and reallocated sectors count. Increasing numbers or a low wearout indicator signal approaching wearout.

5) Environmental Factors & Usage:

Keep your SSD cool and avoid excessive writes. Usage patterns affect lifespan; normal SSDs typically last between 5 to 10 years depending on use.

In short, the most accurate way to estimate your SSD’s remaining lifespan is to combine the manufacturer’s specifications with monitoring tools and your actual daily usage. SMART data readings and popular diagnostic utilities play a central role in this process.
