The maximum data transfer rate for the eSATA port is about 370MB/s. The eSATA port supports port multiplier and is capable of recognizing more than just one disk in a multi-bay enclosure without a RAID controller. This port can be used to connect an external storage drive with an eSATA interface to your Thunderbolt 3 computer. The second Thunderbolt 3 port on the Thunder3 Dock Pro operates the same as a Thunderbolt 3 computer port by supporting Thunderbolt 3 (up to 5 daisy chained), USB 3.1 (10 Gbps), and DisplayPort devices. A single cable now provides four times the data and twice the video bandwidth of any other cable, while also supplying power to bus-powered devices. For the first time, one computer port connects to Thunderbolt devices, every display, and billions of USB devices. Thunderbolt 3 brings Thunderbolt to USB-C at speeds up to 40 Gbps, creating one compact port that does it all – delivering the fastest, most versatile connection to any dock, display, or data device.
