I never paid attention to it. Maybe it was always like that.
My free space on my C SSD drive changes. Every day. Today I turned on my computer, I had 59.4 GB of free space. Now, as I write this post, I have 57.5 GB free.
System clean. I scanned almost everything from second opinion.
Is it normal for an SSD drive to smoothly change free space on the drive? Some indexing? Is it buffering some data somewhere?
Or maybe I have some setting turned on or off?

It's normal for SSD free space to fluctuate due to temporary files, system updates, and cache data. You can use Disk Cleanup tool to remove unnecessary files. If the changes are significant, consider using a disk space analyzer to identify large files or folders.

But that much? Sometimes it can take up to 5GB of free space during work.

What should I do to limit it? Or is it impossible?

Browser tabs each loading a web site could take up a lot, some people have 20-40 tabs open at once. For example, my .mozilla directory holding the cached web pages total 72MB for 14 tab pages. Then all the other apps may take up some space with their work files/temp files. Space used varies with each app of course. A good tool to see is Treesize. Take a look when all apps are closed and take another look with everything open.

I turned off my computer and went for a walk with my dog. I came back and turned it back on. After turning it on, it didn't go back to 59.4GB. Now I have 57.1GB. Is this normal?
SSD refreshes (releases) data so slowly?

SSD refreshes (releases) data so slowly

SSD themselves do not <release> space. Its up to each program to delete the temporary/work files they use.

You may have a program that downloads a big database from work or somewhere, and just like that, your space will be used up.

The program TreeSize gives you a bar chart showing the space used by each folder. And you can drill down to see the space used up by each file inside.

No need to guess whether it is indexing or caching or this or that. TreeSize lets you see EXACTLY where your space has gone to.

5GB of storage space is very little these days. It's normal behaviour and nothing to be concerned about.

Thanks. I'll install it and see what's changing my disk space.

A better and faster alternative is WizTree:

WizTree - The Fastest Disk Space Analyzer

Official WizTree web site. WizTree is the fastest disk space analyzer available for Windows. It reads the Master File Table (MFT) directly from the disk, bypassing Windows and gaining a huge performance boost.

Edit: I never used TreeSize, I don't know how good it is. I got it confused with the WinDirStat program. WizTree is a better alternative to WinDirStat.
