Samsung 860 EVO SSD write/read speed issues

hi, I decided to check the write speed on my two Samsung 860 EVO's on my music production pc, but I don't fully understand the numbers.

Here are the test for Samsung 860 EVO 1 GB which is the OS hard drive:

Why is the numbers so large, like over 5 thousand?

Here are the test for Samsung 860 EVO 2 GB:

Here the numbers are in hundreds, and are too low. It should be like 550mb/s or something.

Tested also in CrystalDisk Mark same numbers. Anybody knows why?

On the 1TB you probably have Rapid Mode enabled, it's a RAM cache, hence the ridiculous speeds. I don't know about the 2TB though, it does look low... How is it connected to the system? Maybe it's setup as IDE instead of AHCI?

Yes I do have rapid mode on the 1GB hard drive (it uses more of my ram so it goes faster?). When I turn off the rapid mode I get the same "bad" numbers as the other hard disk:

Is it smart to have the rapid mode on, on a music production pc (I have 32GB of ram)? I gonna leave it off until I get the right numbers around 550mb/s.

I gonna open my pc in a couple of days cause I gonna change a fan and clean the pc. I gonna see how the sata is connected. I have maybe used the wrong sata ports or something like that. When I look in the bios I can only see my dvd player and none of the hard drives in the 6GB grey sata ports. My motherboard has four other sata ports that I thought did the same. I guess not. I also gonna try and change the sata cables on the hard drives. I report back when I have tried it. (I do have AHCI enabled in bios).
I have attached pictures of the sata ports of my motherboard.

Solved, it shows normal numbers when I changed the SATA ports from A to B (look in attachment over). I'm not sure what those two SATA ports in A is supposed to be used for, but when I read the manual closer it looks like only B is SATAExpress
