It's a metaphor. The SATA bus is not as wide I.e. data bandwidth because it can only use part of the entire data bus into the processor.

This is one of those that makes me wonder if it's a real question or are you just messing with us? Prove you are not and ask about a real computer problem.

Can you help us help you? Happy to discuss computer theory in the abstract, but do you need specific help with a particular model? A desktop or a laptop? Only a few HP consumer models can use a pci-e M.2 mSSD but such a drive is roughly twice as fast as a standard SATA SSD or mSSD. Very broadly, the difference is that a pci-e device is closer to the processor and plugs right into the processor's main 6 lane highway with nothing in between. SATA on the other hand is a 2-lane side road off the main highway. Hope that helps.

HP Recommended
