The Three Libraries

Your school has three different libraries for storing books. The Digital Library (SSD) has electronic tablets - find any book instantly, but expensive per book. The Traditional Library (HDD) has thousands of physical books on shelves - cheap to store lots, but takes time to walk and find them. The Archive Warehouse (Optical) has books in sealed boxes on pallets - very cheap to store, portable, but painfully slow to access. Each storage type has its perfect use case!
