Faster way to read the raw data on disk/drive

I wonder if there are any faster ways to read the raw data on disk/drive under Windows.

Currently I am using Windows API CreateFile:

CreateFile("\\.\PHYSICALDRIVE2", ...)

and

CreateFile(\\.\C:,...)

to read the raw data on disk or drive. But I want to find a faster way

Can you use file mapping to view raw data? I've used this before to speed up general file usage speeds, not raw data though...?
