Is it possible a raid array to work with ahci mode in bios?

[alexis1986cy]

I recently replaced my old corsair force 3 120gb ssd with a Samsung 840 pro 128gb ssd to use it as the os drive. I also have 2 old 74gb raptors in raid0 for games and 1 wd caviar black 750gb for storage. Before installing the 840 pro ssd i had raid mode in bios and everything was working ok but when i tried to install windows 7 in ssd it wouldn't let me because i had to change to ahci mode in bios to be able to install them. So i switched to ahci mode and windows 7 installed ok then i installed samsung magician and did AS SSD and crystaldisk bechmarks and the readings was perfect. The strange thing is that the raid array is not broken when i changed to ahci and i can see raptors as one disk and the benchmarks give me the performance of raid 0 so it looks like the raid array is working even in ahci mode. Is this possible i searched in google but can't find an answer if it's possible a raid0 to work in ahci mode? I want to note that i did the following changes to registry and i did not installed intel rapid storage drivers only samsung magician:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pciide
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\atapi

the "start" values changed from 3 to 0


PC specs:
Intel Core I7 2600k 4.2GHz
Gigabyte GA-Z68AP-D3 (rev. 1.0) with latest bios
Corsair Vengeance 1600Mhz 2x4GB ram
Samsung 840 pro 128GB ( ON SATA3 PORT)
2x WD Raptor 74GB (ON SATA2 PORTS)
WD Caviar Black 750GB (ON SATA3 PORT)

On Intel motherboards, enabling RAID for the chipset storage controller also enables AHCI. Non-member disks (disks that are not part of a RAID) will run in plain AHCI mode, while member disks will run in an AHCI compatible RAID mode.

Yes i know that but i want to leave it to ahci mode in bios so i can have full control of samsung magician software. My question is that my raid0 raptors seems to work ok now but i want to get a sure answer that it's possible a raid 0 to work even with ahci in bios and not raid mode.

here is the results of the raptors in raid 0 with ahci mode in bios

They may work. The chipset RAID mode is simply a firmware assisted software RAID. It just allows a RAID volume to be booted from, it does not accelerate operations in the same way that a hardware RAID controller from LSI would.

In any case, enabling RAID mode should not inhibit the operation of your Samsung software.

In my case when i set raid mode in bios i get this message from magician: "Magician cannot communicate with the below Samsung SSD. Please check with other compatible storage drivers and try again..." and i don't have full control of the software features.

Hi Alexis, did you find a solution ?
Thanks
