Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)
