Hi,
Snapshots are by default taken in the same folder as the VM.
I'm not sure if you can change that folder, you probably can by setting the workingDir.
However it is not something I have experimented with recently, nor do I recommend it.

Also not sure what kind of memory stick you are using to run your VM from. I've tried that in the past and it was pretty abysmal in both performance and reliability.
Perhaps it will work OK if the stick isn't a traditional one, but a SSD type of stick.
