Personal computers typically have six to eight USB ports on the front and/or back of the system unit. USB ports on mobile devices usually are smaller than those on personal computers.
As in computer technology eSata is the combine connection between different storage devices. Any USB or eSata can be attached by this port, which was created in 2008. The sockets for both devices are placed superbly, so they can be attached easily. An eSATA port, or external SATA port, allows you to connect a high-speed external SATA (Serial Advanced Technology Attachment) hard disk to a computer. As it’s cleared that both USB and eSata drive can be connected through this device. There is no such formal approval from any organization, you can use it on your own risk.
