That laptop is definitely only SATA-based. You're overlooking all the other parts in different machines that might explain the variations. Unless you're testing the drive in two identical setups, it's hard to say the SSD is the issue. Trying another drive and getting the same results reinforces my idea. Your SSD seems okay. What you're facing is the overall differences between systems. The laptop is likely nearly 11 years old.
It seems the question is about understanding OP's motivation. What is the underlying reason they are discussing this?
Did you check the laptop drive on the desktop? The screenshots show two different drives.
I rarely encounter drives handling hundreds of MB/s writes from an SSD, as that would be extremely damaging to its longevity, particularly when not in use. I've also conducted CDM tests before, but the results were affected by measurement errors.
Having six gigabytes of RAM makes it simple to observe heavy processing. Still, the operating system doesn’t appear to have evaluated the laptop’s runtime capabilities fully, so we can’t confirm the actual performance.
