clean install and now 2 partitions?

[50L]

Hey Guys!

Right before catalina, still running 10,14 I did a clean install ( used internet recovery mode for this ) all went fine but when I installed all my apps again I noticed I had an extra partiton?

Thinking something went wrong, I did 3 weeks later another clean install, this time for mac os catalina, and same thing happened.

after doing the clean install I also changed my fusion drive to an SSD

So now I have the apple SSD still in it ( 128GB )

I have apparently a partition that's just for the OS on my samsung SSD
and I have another partition for all my files

Would it be SAFE and possible to copy my OS partition to the Apple SSD, and then delete the samsung OS partition?

Oh, boy here we go again...

About the read-only system volume in macOS Catalina or later - Apple Support (IN)

macOS Catalina or later runs in a read-only system volume, separate from other files on your Mac. When you upgrade to macOS Catalina or later, a second volume is created, and some files may move to a Relocated Items folder.

You should not delete that system partition (Naamloos) from the samsung SSD. That is your boot partition.
Catalina adds that second partition (Naamloos - Gegevens), which is part of the install. Leave both of those partitions.
If you want to use the internal SSD ( your internal SSD, showing as the name "Naamloos 2", then I suggest that you create the fusion drive again. Reinstall Catalina, and import from your backup (probably on the external Seagate? ? )
It makes no difference what you do. Catalina will add a second partition. Do NOT confuse things by adding a second partition before you reinstall Catalina!
