I have my virtual machine running on a USB 3.0 device connected to my 15" MacBook Pro Retina, the USB drive seems reasonably quick in benchmarks, yet the virtual machine itself is horrifically slow to use. If I load up Task Manager I can see that the disk usage is stuck at 100% with transfer rates of between 1.0MB/s -> 8.0MB/s, with average response times of 8000ms+. Obviously something is seriously wrong with this setup, however before I go out and spend a few hundred pounds on an external SSD drive, I just wanted to make sure that it really was the cause!
