just because you don't see the call doesn't mean it doesn't exist. (so far you have show little to prove your cleverness)

download RAWREAD and measure read speed throught the file system,

a:> RAWREAD C:\PAGEFILE.SYS

and compare to read speed from raw disk

a:> RAWREAD 0

should be close.
As said before: talk is cheap. but we have politicians for that.
