Yup, if you are thinking of an external drive, there is almost no performance difference between USB 3.0 and eSATA.

The below is a 4 HDD version.
You will have an orange wire (+3.3V; not used in the current SATA drives) in addition to the four wires in the pictures. Make sure that the distance between two connectors is exactly the same as the distance between two HDDs in your case. Otherwise it would be very hard to attach the cable to eight HDDs.
