That is definitely a big issue in a production environment, where you're more likely to be running multiple VMs. But in a developer's typical environment, that is going to be massively outweighed by the terribly slow access via USB 2 or Firewire. > I.e. if your vm lives on the same hd as your os and your programs they are > all competing to read and write at the same time. > > Having a separate hd, internal or external solves that problem. (i have an > external 7200 rpm firewire drive). A separate internal HDD definitely makes a big difference, but I can say from experience that the transfer speed of Firewire just isn't enough. I got an external eSATA drive, and that's sufficient, but I can't tell any significant difference (for me) from the internal SSD in my primary laptop (other than not having to store these giant files on my limited internal space).
