I would suggest that if you want E-SATA, that you think about buying an enclosure and putting a drive in it.
I bought a USB 2.0 and E-SATA enclosure for only $30 or so and love it.
I wouldn't pay double the price, but for me it was only like $10-15 over a standard enclosure.
The speed is nice. It's just like running that disk inside my computer.
