Hard drives served as the primary mass storage solution for Amiga computers, offering significantly faster data access and larger capacities than floppy disks. While early Amiga 500 systems typically relied on external SCSI drives or third-party IDE controllers, big-box Amigas like the 2000, 3000, and 4000 featured internal SCSI interfaces, with later A600, A1200, and A4000 models incorporating built-in IDE controllers. These drives utilized Amiga-specific file systems such as OFS (Old File System) and FFS (Fast File System), enabling permanent installation of the Workbench operating system, applications, and games while dramatically reducing loading times.
