The Intel P55 chipset is only SATA 2 capable, so to bring SATA 3 they use a Marvell controller that runs off the PCI Lanes of the P55 (my guess is it's a one lane but I might be mistaken). It seems that there is quite a number of limitations with using a 3rd party controller in this case.

 

So be patient and upgrade to a newer platform lol.

Upgrading to a newer platform is the only way you're going to get native SATA 6Gb/s support from the Intel chipset.  The older Marvell 6Gb/s controllers are marginal at best even on a single SSD.  So right now your only real choices are be happy with where you're at or update your platform.
