In 1973 the IBM Winchester Drive was introduced with three removable, sealed data modules. The rest of the operating system was basically a command monitor. In 1961, the IBM 1301 Disk Storage Unit was released, which utilized heads that floated on a thin layer of air. Before the Winchester architecture, removable disks were like removable disks today, in which the read/write heads remain in the drive and make contact with the platter after the cartridge is inserted.

In 1964, the IBM 2311 was the first standardized disk drive, which could be used across multiple versions of the System/360 computer. The IBM 3340 Direct Access Storage Facility, code-named Winchester, was introduced in March 1973 for use with IBM System/370. Each generation of disk drives replaced larger, more sensitive and more cumbersome devices. The disk drive grabs the floppy by its center and spins it like a record inside its housing. 2008: The 32 GB SDHC and 12 GB Micro SDHC is in development by Sandisk.

The new Winchester hard disk drive was a revolutionary device, which revolutionised the way hard disks work and are built to the presence day. These floppies were encased in hard plastic, but the name stayed the same. [2] The disk drive created a new level in the computer data hierarchy, then termed Random Access Storage but today known as secondary storage, less expensive and slower than main memory (then typically drums and later core memory) but faster and more expensive than tape drives. Drives with smaller media generally conformed to de facto standard form factors. Another term for hard disk drive.
