I want to put Steam on my external hard drive that I found a while back. It's a Seagate FreeAgent 1 TB hard drive, and uses a USB 2.0 to plug into my computer. I heard somewhere USB 2.0 is slow for games and eSATA is better, so I want to know if there's any such thing as a USB to eSATA adapter, but the other way around, as in on NewEgg and Amazon, there's always an eSATA port and a USB 2.0 end. I need a USB 2.0 port and an eSATA end.
