Daisy Chain

I have a G-drive w/TB 4TB drive one USB port, one TB port, am looking at 4TB G-Drive Thunderbolt 3 with two TB ports. If I use the the one TB port on the one drive can it be daisy chained through the TB3 Ports to the Mac. Before I spend the money on a new drive can these be Chained together, if so how do they appear on the Mac, as two drives or as one larger drive…

Thanks
