Per the Viridian expansion patch notes:

We are making it much easier to haul PI commodities as well as it now requires fewer active inputs to manage since the space of all storage facilities and spaceports is effectively doubled.

Volume of all PI commodities reduced by 50%.

EVEPraisal is currently showing the old volume numbers.
