It will be slower if you use USB 2. I use an eSATA adapter on my
desktop talking to a Thermaltake BlacX docking station which accepts
either eSATA or USB 2 as input.
<http://www.newegg.com/Product/Product.aspx?Item=N82E16817153071> and
performance on external drives is the same as internal (although my
internal/external drives are both SATA II and not the latest SATA III).
Still plenty fast.
Thermaltake also makes a USB 3.0 version of the docking station which
can take SATA I/II/III drives in the dock.
<http://www.newegg.com/Product/Product.aspx?Item=N82E16817153133> Early
reviews were not good but it appears that was due to poor early USB 3.0
drivers on the computers and not the thermaltake hardware. USB 3.0 I
believe is theoretically faster than SATA III but since the final speed
can't be any faster than the SATA III drive in the dock you might as
well stick with eSATA III if you have or can get it on your machine.
I have USB 3.0 ports on my HP Win 7 machine which I've used to try and
drive my Thermaltake via a USB 3.0 to SATA adapter. It's unreliable
enough that it can't make a complete clone of a large drive without
generating an error of some sort. I don't know if it's the HP USB 3.0
port, drivers or the USB 3.0 to SATA adapter. Anyhow I've given up for
the moment and gone back to my very reliable eSATA adapter.
Maybe one of these days I'll buy one of the newer Thermaltake USB 3.0
drive docks and check it out.
