-----------------------------
Specific steps for a successful clone operation:
-----------------------------
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
If you are cloning from a SATA drive to PCIe/NVMe, install the relevant driver for this new NVMe/PCIe drive.
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive

If you are going from a smaller drive to a larger, by default, the target partition size will be the same as the Source. You probably don't want that
You can manipulate the size of the partitions on the target (larger)drive
Click on "Cloned Partition Properties", and you can specifiy the resulting partition size, to even include the whole thing

Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe all partitions on it.
This will probably require the commandline diskpart function, and the clean command.

Ask questions if anything is unclear.

There's a right way and a wrong way to do this.

I do have a full backup yes - in the cloud, maybe I just YOLO it. Samsung Data Migration says Drive 3 and Drive 4. I hope drive 3 is the correct one, HWINFO64 has the correct drive as the first one too

Hopefully you have a full backup of that data? Because if you choose wrongly...

What are you trying to accomplish?
If migrating, why move same to same?

If you run the migration app, the current windows C drive will be the source.
The remaining drive will be the potential target.
I think you misunderstood, I have my C drive with windows on it, 500GB. And I have two Samsung 970 Evo Plus M2 SSds., One of them has important data, one is brand new. I'm trying to clone my C drive onto the brand new 970 Evo Plus, but Samsung Data Migration doesn't say which 970 Evo Plus is which

Yes, I missed that 500gb > 2tb.
I would be paranoid about selecting the wrong target drive.
You really should have only the desired 2tb target installed to do the copy.
Take the time to do it right.
Disconnect the drive with good data temporarily.
Yes, it is a pain.

Otherwise, be certain you have an external backup of whatever you hold dear.
Prevention of a problem is easier than recovery.

And, on some motherboards and processors, which m.2 slot is used can be important.

Once you select the drive, does it not show the drive letter and capacity/free space on the drive before you hit start? I mean in your screen shot it shows the C drive selected for the target because you haven't picked one of the 2 SSD's. Pick one, nothing is going to start until you tell it to. You could also go into device manager and disable the one you don't want written on.

Data Migration does not show what space may already be consumed on the target.
Just what it will be after the migration.

In his pic, he has one of them selected.
