Electronic storage has been moving away from discs for quite some time. Music is kept on our phones rather than in giant CD books that get left in the car, important documents are kept on the cloud, and flash drives and cards are becoming ever cheaper and much larger in size. Even video games -- the last bastion of optical media -- have been moving toward the cloud. However, games arguably benefit the most from increased storage, and that's why Sony and Panasonic's new 300GB disc is extremely promising for the future of gaming.
