Explanation: 

Detailed explanation-1: -eSATA is a SATA connector accessible from outside the computer, to provide a signal (but not power) connection for external storage devices. eSATAp combines the functionality of an eSATA and a USB port, and a source of power in a single connector. eSATAp can supply power at 5 V and 12 V.

Detailed explanation-2: -1. Speed: eSATA external hard drives usually perform better than USB 3.0 external hard drives for the following reasons: Interface speed will limit hard drive speed. Therefore, USB 3.0 external hard drive speed won’t exceed 500 MB/s, while eSATA external hard drive can exceed that speed.

Detailed explanation-3: -You’ll find it was the “fastest” throughput interface (1.5 Gbps to 6 Gbps) on most PCs before the advent of USB 3.0 and Thunderbolt (10 Gbps). Each eSATA device connects on a one-to-one basis with the PC, so you’re not sharing the signal via an internal or external hub.
