Would a high quality USB 3 SSD beat the speeds of a SATA II internal 7200rpm for gaming?

Would a high quality USB 3 SSD beat the speeds of a SATA II internal 7200rpm for gaming? References I have a gaming laptop and a desktop that I switch between pretty regularly due to not being home often. Rather than purchasing two SSDs, I was considering whether I could get away with getting a single USB 3 SSD and installing the games I needed on it instead! I currently have SATA II , 7200rpm drives drives in both. Standard drives, basically. I\'m looking to see a performance increase on load times on both machines, and was curious whether the USB 3 SSD would be able to outperform them in this regard or not. It seems like it would, but I\'ve heard latency across USB 3 can actually be pretty bad, so I don\'t want to put out the money necessary to get this drive and find out that, in actuality, it comes out slower! Just for a side note- the laptop does not have an esata drive, so I that isn\'t an option. :-\\ So what do you guys think: Would a high quality USB 3 SSD beat the load speeds of a SATA II internal 7200rpm for gaming? By external SSD, I mean an SSD drive in a USB 3 enclosure for 2.5\" drives (claims 5Gbps)
