msata

Hi, I have some machines with Proxmox installed. The machines are HP8300 USDT. They have an mSATA port and two SATA ports. The question is... in the two machines the mSATA ports only negotiate at 3Gbps, the mSATA disks are 6Gbps but only run at 3Gbps. I know mSATA ports works at 6Gbps, right...
