What is meant by "Single Driver Per channel"? SATA

A channel in this context is a single electrical connection. SCSI of old connected multiple devices to a channel and addressed each device through a feature in the signaling protocol on the wires. SATA lacks this as it is purposely a simpler protocol.
Which begs the question, So how to port-multipliers work, then?
This is an optional extension to the SATA protocol that not all controllers implement (it adds cost). When used with a port-multiplier you can actually connect multiple drives to a single channel, as the port-multiplier handles the drive-addressibility.

Thank you for your help it is appreciated. By single electrical connection would this mean one cable from the drive to the motherboard in the server/PC? Very new to this – topcat – 2013-03-24T14:42:12.460
@topcat Yep, that's exactly it, one cable. – SysAdmin1138 – 2013-03-24T15:56:19.100
