AHCI and Me (question)

[Redemption213]

My basic question is this, is it worth me re-installing OS or are my SSD results normal?

The back story:
Laptop: MSI GX660R-646UK
Chipset: Intel PM55 - SATA 3.0Gbit/s
Drive 1: OCZ Agility3 120GB - OS Windows 7
Drive 2: OCZ Agility3 240GB - Steam Library

The Laptop used to have 1tb (2 x 500GB) in RAID. I whipped them out and stupidly didn't changed from RAID to AHCI in both BIOS and Intel Rapidstore Utility before installing the OS.

Here are the results from AS SSD Benchmark, which appear pretty poor (even for 3Gbit/s, I don't know ???).

As you can see, they're running in iaStor which is Intel Rapidstore AHCI and/or RAID.

The thing that I can't fathom is that my Laptop WAS and still is set to RAID in the BIOS. Is it defaulting to AHCI despite this? Here's the AHCI reg entry:

I'm not so sure because when I change to ACHI and try to boot, my OS blue screens. Am I going to get better results by reinstalling my OS under AHCI?

yes thats right raid and ahci contain the same drivers,so running in raid mode will be fine,google enabling ahci win7 after installation and follow the simple reg tweak

stay in windows,download/run this reg file,reboot into bios and set to ahci mode,save exit bott into windows and thats it,no reinstall needed

Tried, but still BSOD at Windows Logo

it could be because its a laptop,raid will work in ahci mode just the same

Do those AS SSD scores seem normal for 3Gbit/s?

 

[wazza300]

yeah they look fine,better than my score on sata3 ports,but im using a tiny 60gb ssd,the bigger the ssd better the score

test with atto benchmark also
