Can Ichtyop read circulation data from external hard drive

Hi,
I'm grad student and planning to use Ichtyop for the first time to do a simple model of dispersal patterns so my question might be obvious.
The ocean circulation data for my project will be given to me from another institute and it's 4TB so I'll have to store it on an external hard drive as storing it on a server is not an option unfortunately. 
Will that be a problem or can Ichtyop read the hydrodynamic data from an external hard drive? Is there something I should think of? 
Many thanks
Vivien
