My favorite desktop just got better. The 21.5-inch and 27-inch models now have faster processors and graphics. The new desktops also introduce Fusion Drive.
Fusion Drive is an innovative new storage option that gives customers the performance of flash storage and the capacity of a hard drive. It combines 128GB of flash with a standard 1TB or 3TB hard drive to create a single storage volume that intelligently manages files to optimize read and write performance. Fusion Drive adapts to the way you use your iMac and automatically moves the files and apps you use most often to flash storage to enable faster performance and quicker access.
