Thanks for the information and sorry for the confusion.
I can confirm that it is completely normal and expected, nothing "can be done about this" (and nothing needs to be done).
Not sure why you did not find the answer, as it is already discussed on the forum:
and also described in the Help too:
(see the bottom of the page about SSD health)
No, I can confirm that you do not need to worry.
As the software displays the status is PERFECT, there are no problems with the SSD.
Yes, the health is not 100%, "only" 99% - but it is still "EXCELLENT" see next to the health % bar.
As you may know, the memory cells in solid state devices experience wear during each write operations and each cells tolerate only a limited number of overwrite passes.
The "wear-leveling" feature of the SSD tries to hide/minimise this effect but generally the SSD device reports the overall health of the memory cells by various attributes.
If there are no further problems found, Hard Disk Sentinel reads these attributes which determine the complete health of the solid state device.
This is what you can see in the text description area: there are no problems found, but the 173 Erase Count attribute determines the overall health of the device. If you want, you may check how that attribute changes with time on the S.M.A.R.T. page.
This is completely independent from software, OS, restarts and so: as the amount of written data increases, the health slowly but surely decreases.
This is normal - and you do not need to worry about it now, as only 1% of the total lifetime used.
I'd suggest to please use Report -> Send test report to developer option, then I can check the complete status.
The best would be if you can send developer report now (for reference) and maybe later upon any possible change, degradation, as this always helps in investigating a particular model, its reported health.
