I am a developer that works out of a home office. We have pretty decent performing corporate laptops and we run VM Workstation in our daily work. In order to improve performance, we run the VMs on external USB drives. I would like a 1TB drive that is high performing for this application. I/O is key, so most likely 7200RPM. We've tended to use portables as we sometimes travel, so USB power is a nice to have, but not the only option. My last drive was a Seagate GoFlex portable. It was 5400, but I could use an eSata cable to get better than USB2.0 transfer rates. My next laptop (already ordered) will just have USB 3.0.
Any recommendations for this application?
