Hello guys, It's my second post here. The first time I came with a problem in my raid0, so now I want to do another.

I have 3 HDD and 2 of them are in RAID0 mode and I have 4 SSD's and I want to do a RAID0 with them.
I was checking the M7F Asus Specs on the official site and there is something there about 4x Sata6, but the M7F has 6 not 4 (without count the Sata-E)

As I already have a raid my bios is configured to RAID mode ofc, but I can not do the raid with my 4 ssds, because them doesnt show up in the Intel RST, just show 2 HD (raid0), and 2 SSD.

Why I cant do another raid with 4 ssd? And why in BIOS I cant see all the disks connected in my computer?

I got some pics to demonstrate better my problem
