Would someone be able to tell me why my 840 evo's bench numbers are WAY TO HIGH?

Hello! this is my first post here (have yet to introduce myself)

I want to get straight to the point. And I apologize if this has already been addressed...

My 250gb Samsung 840 evo, is reporting numbers that are WAY TO HIGH. In some cases over 8Gb/s...

I have the gamut of benchmarking apps, ran all 3 times within an hour, and got the same numbers within a margin of error.

The drive is almost full, and i am considering on getting a 750 soon. (also have a 2tb WD as storage)

In the image:
ATTO - up to 3.18gb/s READ, but only 454mb/s WRITE
AS SSD - 4gb/s read, 2gb/s write in sequential, but only 500/mbps under 4k/64
Samsung Magician - 5gb/s read, 4gb/s write
Crystal - OVER 7gb/s read and 6gb/s write, but 600/400mb/s under 4k...

Any discernible reason for this? Is this unique?

System:
Core i-5 4670k
32gb corsair vengeance pro
ASUS Sabertooth z87
EVGA GTX 780 SC edition
250gb samsung 840 evo
2tb WD green
Win 8 pro.

You've got RAPID turned on.

It caches to your RAM, so you are basically benching your RAM.

Interesting, that's what i thought it would be... but i have had rapid on before, and only got 800mb/s-1gb/s

I'll turn rapid off and see if it changes. Is rapid even necessary?

HAHA nevermind, i'm an idiot, the last time i did a bench with rapid on, i had some crappy 1333 patriot memory...
I recently upgraded to the corsair ram, and that greatly sped it up... that explains it.
I didn't know thats what rapid did... hmm.

I turned rapid off and now they are exactly where they should be! Thanks!

Hmm... never heard someone complain that their speeds are too FAST. I just updated to Samsung Magician 4.4 and check out the speed:

NEVERMIND. I too forgot about rapid mode. Numbers are now very close to spec.
