Or just buy the biggest fastest drive your CPU box has a port to handle and your Wallet can afford .
Then go from there. No one, including you, can predict the actual reduced size of each file. Averages lead to disappointment in my experience. Knowing what level of quality you can live with may help but you will find yourself collecting a lot of files from a lot of sources with differing quality and therefore a wide range of sizes. Yes, you can set up preference settings for rips but you will find you really need some changeable presets to accommodate the disks you source from as their quality has varied according to the technology and studio savvy of their origin. If 3-4 TBs for around $100 or less for an external USB 3 seems out of the question an sober assessment of the listening needs may help. Wallet size can simplify the choice.
