gtvr - I'm using PCI controller as mentioned above. Haven't tried MB controller.
marcellis22 - RAID 0 is pointless with PCI controller solution, I GUESS. Kinda funny there's lot of them on market considering the effectivness u get.
Now i have PCI controller so I'll got to deal with that. I want to use all available space on disks, so that's wha I said JBOD after seeing RAID 0 doesn't have too much effect...tho I guess it's the best to leave it this way.
