For a single eSATA drive, this adapter might work well; However, if you have an eSATA enclosure with multiple drives, this adapter will NOT work. It supports only one device.

They probably have another product that supports multiple drive enclosures: https://smile.amazon.com/StarTech-com-Thunderbolt-eSATA-Adapter-Windows/dp/B079H56RNW/
