Does this support 6 Gbps simultaneously on both? (as in 12 Gbps total; 6Gbps + 6Gbps for two SATA III devices connected?)

Or is this limited to a TOTAL of 6Gbps?

Accepted Answer

with SATA III the transfer speed is 6 GPS for each connection. However the connections are side by side not cumulative (in other words on a motherboard with 6 SATA III connections. The max speed is 6 GPS for each connection). Both channels can run at 6 GPS. for example copying files from a Disk on Channel a to a disk on Channel B the max speed is 6 GPS between them
