Mike, thanks for the explanations. The way I understand it is you are talking about external disk drives where the electronics are designed for USB2.

I did all my runs with HDDs I recovered from my laptops after I upgraded them to SSDs. Those disks are run in external enclosures that are designed for USB2, USB3 and eSata. I also used a 3.5" internal drive (Barracuda) in an enclosure.

Yes, I was only referring to externals with the relevant interfaces.

If I understand Mike correctly, he is correct. If you plug a usb 2.0 thumb drive into a USB 3.0 port you will get much faster performance from it than plugging it into a USB 2.0 port.

By the same token, Try a sata2 external into an esata2 port. Then try that same sata2 drive plugged into an esata3 port and see if you get better transfer rates.
