Upgrading to 4TB HDDs (1 Viewer)

I have a small quandary

I have my main machine with a sandybridge Z68 MB running win7x64
I have 2x SATA 6Gb/s both with SSD's attatched
I have 4x SATA 3Gb/s from the Z68 northbridge chip with 2TB drives each

Now I know the 6Gb/s ports will allow me to use 4TB drives, but I need the bandwidth for the SSD's
So here's my question: Will the SATA 3Gb/s ports support 4TB drives when formatted to GPT (as individual drives, not using RAID) or will the port itself not recognise over 2.2TB on each drive

Looked all over and can't find an answer anywhere
My Machine is getting pretty full and needs an upgrade. Would rather just upgrade the drives to 4TB than to have to upgrade to a new haswell MB with 10x SATA 6Gb/s ports and processor as well

All my expansion slots are full BTW, so no room for add-on controller cards either

Can anyone help me here before I waste my time/money/effort/hair??
