Hello all, I'm planning to move my multiple Poser runtimes from my PC's master drive to an external HD, but I have a couple of questions and hope you experienced folks can enlighten me on them:

1.   Does Poser runtimes run noticeably slower in an external HD with USB2 connection than in an internal SATA HD, when I run the Poser core application from an internal SATA drive?

2.   Does Poser run even slower  when I have the Poser core application and all the runtimes installed and run in an external HD with USB2 connection?

My computer is a Core 2 Duo, with a SATA master drive, 1.5G system RAM, 256MB dedicated video RAM.

Your input is much appreciated!
