Hello,
Refering to : http://downloadmirror.intel.com/21340/eng/dq77mk_TechProdSpec02.pdf
On page 16 : it's told 6Gb port
Letter : X SATA 6.0 Gb/s connector (multiplexed with an mSATA port, routed to the PCI
Express Full-/Half-Mini Card slot) (gray)
On page 17 : for the same connector 3Gb
I bought a 6Gb SSD mSATA drive and it's detected as 3Gb under ESXi 5.1.
I have no hope, cause i think it's a bus limitation but if an intel Employee could give me a clue for the technical possibility by design.
And if so for a bios release...
TIA,
