Where do Drive numbers come from and why do they change ?

[hdsentinel]

The manufacturer defines the role of each attributes on the S.M.A.R.T. page.
This is why it is important to understand how they work, what kind of information they show (if we prefer to check manually) or simply let Hard Disk Sentinel understand and display the results of the investigation.

The SSD may periodically re-freshes the values but this may not happen immediately. With other words, it is possible that "your action" also triggers increase of the value (if you perform different read commands) just it may require some more time.
If you prefer testing, you may use Disk -> Surface test -> Read test function in Hard Disk Sentinel.
You may define different areas for testing, for example check only first half of the SSD and then the other - just to verify if the counter increases the same way.

But personally (according the report) I'd say that this change is completely normal and until you see and kind of error in the text description, things are fine.

Thanks

I will try to stop worrying then.
