What is the point of suggesting a USB3 adapter to people who need a device that *adds* USB3 to their machines.
The thunderbolt to USB3 adapter is primarily for people who have thunderbolt ports on their Mac but don't have USB3. A USB3>eSATA is useless to them.
hehhhe , you must be a little creative. i guess! lol
You run out USB3.0 port, may due to multiple USB3.0 drives
If you are using USB3.0 to eSATA adapter + eSATA Port Multiplier box /enclosure
Then a SINGLE usb3.0 you can connect up to 5x HDD - fully hot swap
This certainly would free you some USB ports
Or to enjoy the Thunderbolt bus bandwidth - using
Thunderbolt JBOD box, move all your HDD to it. This also free some of you USB port
