Improving SSD performance

True, bat the issue is not related to wearing an whatever Windows might do in terms of maintenance.
The issue with Samsung SSD firmware is that the cells that have been written long time ago have a slower read speed.
Since the wearing leveling manages the way data writes are distributed and Win maintenance cleans cells that are deleted, you see there is a case.

Most laptop manufacturers are mixing a number of OEM SSD brands for reasons of production continuity, and when they (if at all) decide to upgrade the firmware of any of those SSDs, they have processes in place that prevent you from flashing the wrong firmware

The screen shots are showing Samsung
The thing is: Samsung 840 EVO SSD have this bug and I recently updated the firmware+refreshed the data using the Samsung tool on my laptop (not SP3).
The fact that SP3 SSD is affected by the same bug is to be proven BUT I run a test before, I refreshed the data with the tool and run a test after.
These are the results:
- before the refresh:
- after the refresh:
Now, to be honest, this is not exactly what I would expect from this bug (the first graph should look different) but it's definitely not a placebo effect
But those running Hynix SSDs who try this will get errors and frustrated....The screen shots are showing Samsung
No error should be given, since the tool is agnostic (actually it's even for mechanical HDD).
They would (probably) not see any improvement as well.
Mixed results notwithstanding it should be examined but the danger is others not so careful or knowledgeable getting off track. Which is why a quick investigation and response from MS would help nip this in the bud before wild speculation and misinformation proliferate but that's the nature of the Internet.

If so then I don't have an answer. I have installed dozens Samsung EVO drives in new systems and as replacements over the last several months and haven't seen a problem. There was a firmware upgrade for the Pro 250 about 2 months ago but I don't know what that upgrade addressed. There hasn't been one for the EVO in some time.
If the drive is in fact a standard EVO drive the Samsung Magician should run and when executed will tell you if there is a firmware upgrade, on the fly. However, if it is an EVO drive it could be an OEM version so that may not work.
The Magician software has an OS tuneup component that can be run at any time. I;m not certain what it does but I typically run it once every 6 months for the systems I support that have Samsung SSDs installed.

The Samsung controller/firmware does garbage collection, which sounds like what you are talking about. That makes a previously used cell ready for the next write without having to go clean that cell first. It does it when the system is idle.

Sadly, the Samsung Magician software does not recognize my SP3's Samsung SSD as being a Samsung SSD! Just wanted to tune my Samsung SSD for performance. I really love the Samsung Magician software though, but had to uninstall as it's useless on the SP3.
Wonder what kind of SSD speeds the hynix SP3's are getting compared to my nerfed Samsung SSD.
