GA-P55-UD4 and 2 white sata connector

[FlyAway]

Hi
I have open my case (assembled not by me  ^_^ ) and I have see that I have all the 6 blue Sata port used by my Hard Disks but I have 2 white Sata unused. Someone can tell me if I can use the white connectors like the blue and so connect other 2 Hard Disk (1 SSD and one SATA)?  And, can you tell me what difference is between blue and white and what are the fastest ones? Thanks

Greetings,
Your MB has 2 SATA controllers.

SATA 0~5 is Intel
GSATA 0~1 is JMicron

Both are SATA 3.0Gb/s

See page 8 of your MB manual for reference. 

Like the PCIe x1 slots, these two (white) SATA connectors share a single PCIe lane.  If you connect one drive to either of the white ports, that disk will operate at a maximum of 3.0GB/s.  If you connect 2 disks, the bandwidth is shared 1.5Gb/s.  If you have drives you do not access frequently they can be moved there freeing up one (or more) of the Intel slots for that new boot drive we discussed earlier. 

Cheers

Below is a diagram of the MB.  It shows the number of resources (PCIe lanes) available for the various interfaces.  In this case your PCIe x1 slots and the second SATA Controller (JMB362).

ok, can I use only one but I have read about a RAID function that I DON'T WONT, is possible disable this function? I want use the white connector exactly like the blue, is possible? Thanks

Yes.  RAID is optional.  Just select AHCI as the controller operate mode.  Refer to your manual for reference.
