Buy this enclosure http://eshop.macsales.com/shop/USB2/OWC_Express
So I've decided to go with Firewire 400. I've settled on this external enclosure http://www.newegg.com/Product/Product.aspx?Item=N82E16817347013. This one does both USB 2.0 and Firewire 400, which is good in case I need to hook it up to a machine that does not have Firewire 400.
The latter...
As far as I know, the Superdrive is also a SATA. But I think (and please correct me if I'm wrong) that the power connection is different.
