What's the Windows equivalent and does it also do it every week?
I googled this. And if the AI is right then trimming is done every time a file is deleted. And then when the SSD garbage collection runs the blocks are made available again? So I looked some more.
Here is what I now think is going on. So windows marks a file as deleted but the blocks are still allocated. Trim de-allocates the blocks of the deleted file. When garbage collection runs it doesn't move any of the deleted file because the blocks have been deallocated. This reduces the number of read/write cycles during garbage collection and extends the life of the SSD.

Windows equivalent here, without the annoying email fish routine:
fsutil behavior query DisableDeleteNotifyExecuting "fsutil behavior query DisableDeleteNotify" from a command line you should get a result of zero (0). This means that TRIM is enabled, and no further action is required.
Note that to verify this in Windows Drive-> Properties > Tools -> Optimize the drive should be described as Media Type "Solid state drive". This tells you that Windows will not be racking up writes trying to optimize (defrag) files,

Thank you very much, I think I have one drive that is NOT listed as an SSD drive but in fact is one and that's why it's running and nearly 100% over 80% of the time!! I'm going to upgrade it to Win11 soon so hopefully that will fix the problem, if not I will stick a different drive in there!
What about using sse3 or SSE4_2 ? Every new intel, and AMD CPU has it.
Two questions.
1) If a CPU doesn't have those does the task fail soft or die with a computation error?
2) What software development brings the most benefit to the project? And the related question what software can enjoy the widest use by volunteers?
All that said, the anonymous platform allows individuals, teams and groups to write code to solve the same task as the baseline programs, that may run faster or use less resources.
I am aware of such efforts and use them.
