Grid Analysis and Display System (GrADS)

Hi, I would like to request an portable version of the application Grid Analysis and Display System (GrADS). While the program is small, the data it handles ranges from 20MB to 3 TB (the size my research center is handling normally). But before requesting this, I have a question, would it be alright to run this program as a portable app? Given the amount of data it handles, yes, I would be working with 3TB data soon, would it wear out the life of the usb drive? Does each of the program calculation would need acessing the pendrive?
