Yes I am aware.
It's not an arm moving causing the wear. It's the natural process which every bit of flash ever is susceptible to and bunches of fragmentation can cause more of it.
If you google hard enough I'm sure you'll find I'm not fibbing to you.

Other posts provided links but I still have not seen anything authoritative.
Following, still not authoritative, seems to follow what other even less authoritative sources say. And at least the post date is more recent.
https://www.pcmag.com/how-to/how-to-defrag-your-hard-drive-in-windows-10[^]
That link, and others, state that a SSD should not be 'defragged'. But rather it is 'trimmed'. And that is what that process does.
As noted in my other post, my windows 10 computer does NOT have the stated process enabled. I didn't turn it off. And I think I remember installing Windows 10 directly (I remember because I was annoyed that it didn't come installed out of the box.)
But I can't find anything that suggests whether the default is turned on or off.

No, it's utter nonsense. For at least two reasons.
For one, assuming you are running a recent Windows, NTFS isn't prone to fragmentation anymore in the way FAT used to be in the days of old.
And second, you are just wasting write cycles on that SSD (which are still limited below the lifetime of a "spinning rust" drive) for little gain, if any at all.

Doesn't Windows itself refuse to defrag a SSD? Try running Windows defrag on SSD and it will simply do some 'trimming', and won't show any fragmentation status. That should be clear answer. A maker of OS should know best.

Try this: Run defrag c: from an elevated command prompt.
Be patient, it takes quite a while, and you get:
Pre-Optimization Report:
Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 20%
Largest free space size = 863.72 GB
Note: File fragments larger than 64MB are not included in the fragmentation statistics.
The operation completed successfully.
Post Defragmentation Report:
Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 0%
Largest free space size = 863.75 GB
Note: File fragments larger than 64MB are not included in the fragmentation statistics.

Short answer: No.
Long answer:
Unlike mechanical drives, data blocks aren't stored physically in the same order as they are logically. Blocks are physically fragmented internally in most cases, regardless (including what order the OS believes them to be in). But this doesn't matter, since all blocks are accessed at the same speed (**), eliminating any speed advantage of sequential access (++).
** Hypothetically, a high end drive could read/write multiple physical flash chips simultaneously, allowing a block to be accessed without waiting for a prior one to finish, if stored on a different chip.
++ Some Flash Translation Layer (FTL) structures may have a slight speed advantage from accessing co-located logical blocks (such as unfragmented reads). But the speed improvement would be trivial compared to the speed increase of sequential access of mechanical drives.
While a given manufacture's implementation may vary, the mapping of blocks generally works something like describe on one of these pages:

VS consuming huge amount of memory isn't new (even MS decided to ignore it totally)...
But now I have something new... And it confirmed several times...
I have a solution with around 80 projects in it, only a several loaded at any given time... If I reload a project to change something it will not compile until VS closed and re-opened...
Until that time it will report compilation failed without any actual error, but also without the option to run...

After the last update of VS2022 my colleague reported that debugging with step over and step into didn't work anymore. It was not clear to me if he was talking about C++ or C# debugging, he also uses other debugging tools that might interfere with VS debugging.

Interesting you'd mention that. I installed the latest update last week, and on Thursday/Friday, on multiple occasions, single-stepping (F10) seemed to continue execution or couldn't recover or something like that. I attributed it to me fat-fingering it, but happened enough times that now I see your post, I'm wondering if there's something to it.
In my case that would be C#.

One has to remember that multi-project solutions don't (always) compile if you haven't checked the proper project(s) in the "Build | Configuration Manager" unless you specifically ask to "Build / Rebuild" that project. (Been there)
On the other hand, when VS is "sleeping", it "seems" to release (more) excess memory. I think they're doing a lot of tinkering.

I have a very precise dependency tree, so compiling the main project will compile everything that is outdated - I also mostly do build-solution...
But the main issue is that, there is no error behind the fail and re-opening VS solves the problem - which indicates that VS does no know how to reload a unloaded project correctly... anymore... (which is fixed by re-opening VS and the solution)...

Versus which IDE that uses very little?

To me that would be an organization problem. I would break it into different solutions and if that was not possible then it would suggest different sort of problem.

I recently bought a new bluetooth device and it only uses Bluetooth LE. The Bluetooth adapter on my desktop is too old to connect.
So $16 later, I have an upgraded adapter that supports BT 5.0. My new device connects and works!
But now my older bluetooth devices don't connect... 
clarification: They won't pair with the new adapter.
The difficult we do right away...
...the impossible takes slightly longer.

That's disturbing to hear.
|
|
|
|

So, all of your devices happen to connect to either BT, or BT LE exclusively...?
Can they not co-exist? Maybe installing the LT adapter disabled the older one...check Device Manager and such.
Beyond that, I'm just guessing. I've never purchased a BT device, and those that came with one, have had it disabled.

This morning I tried to print from my Windows desktop and Windows listed the printers I can target. Included in the list was an unknown HP printer! Checking the Control Panel and sure enough the list of printers included a HP device. Now here is the thing:
Years ago, in the days of XP, I bought a HP scanner. When Windows 7 came out, the scanner driver was incompatible with 7 and HP refused to provide a driver for Win 7. So since that time HP products were banned from our house. There is no HP printer in our house or connected to our network!
Why did Windows install a totally unknown HP printer on my machine, probably with the last update? 
I managed to remove the printer from my setup, but this really p**** me off.
Ok, I have had my coffee, so you can all come out now!
