2.5-inch Solid State Drives are one of the most common form factors for consumer-grade solid-state drives. Their small size allows them to be installed in most laptops, desktops, and ultrabooks. While 2.5-inch Solid State Drives typically have lower storage capacities than larger drives, they still provide significant performance improvements over mechanical hard drives. These drives are ideal for users looking to boost system responsiveness without taking up much space.
