Question New NVME SSD has created 48gb for system and reserved?

I've recently bought a new, faster 1TB SSD and installed in into my computer. I want to migrate all my data to this new SSD, so that everything runs that little bit quicker. I didn't have to swap the other SSD out, as I have two NVME ports.
When going to clone my SSD. I noticed that my newly installed one has create a 48gb "system and reserved". I'm not sure where these files are and why they got created and if it's even safe to delete them.
My question is. Can I safely clone my old SSD to this new one without touching those newly created files, as I believe the cloning process will delete them.
I don't really understand how storage works so I've attached some images so you can get a better understanding.

Thanks :)

Pay attention to the middle part, where it talks about managing the resulting partition size on the target drive.


-----------------------------
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
Both drives must be the same partitioning scheme, either MBR or GPT
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
If you are cloning from a SATA drive to PCIe/NVMe, you may need to 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

[Ignore this section if using the SDM. It does this automatically]
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
[/end ignore]

Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD. This is not optional.
This is to allow the system to try to boot from ONLY the SSD

(swapping cables is irrelevant with NVMe drives, but DO disconnect the old drive for this next part)
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.
