History of hard disk drives. In 1953, IBM recognized the immediate application for what it termed a "Random Access File" having high capacity and rapid random access at a relatively low cost. [1] After considering technologies such as wire matrices, rod arrays, drums, drum arrays, etc., [1] the engineers at IBM's San Jose California laboratory ...
A hard disk drive (HDD), hard disk, hard drive, or fixed disk[a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
In the list those manufacturers that also produce hard disk drives or flash memory are identified. Additionally, the type of memory used in their solid-state drives is noted. This list does not include the manufacturers of specific components of SSDs, such as flash memory controllers. [1]
Particularly with the advent of USB, external hard disks have become widely available and inexpensive. External hard disk drives currently cost less per gigabyte than flash drives and are available in larger capacities. Some hard drives support alternative and faster interfaces than USB 2.0 (e.g., Thunderbolt, FireWire and eSATA).
IBM's first hard drive, the IBM 350, used a stack of fifty 24-inch platters and was of a size comparable to two large refrigerators. In 1962, IBM introduced its model 1311 disk, which used six 14-inch (nominal size) platters in a removable pack and was roughly the size of a washing machine. This became a standard platter size and drive form ...
Examples of digital recording are floppy disks, hard disk drives (HDDs), and tape drives. HDDs offer large capacities at reasonable prices; as of 2024, consumer-grade HDDs offer data storage at about US$15–20 per terabyte. [6]
