History of hard disk drives

Main article: Hard disk drive

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 invented the hard disk drive.[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) but faster and more expensive than tape drives.[3]

The commercial usage of hard disk drives began in 1956, with the shipment of an IBM 305 RAMAC system including IBM Model 350 disk storage.[4] US Patent 3,503,060 issued March 24, 1970, and arising from the IBM RAMAC program is generally considered to be the fundamental patent for disk drives.[5]

Each generation of disk drives replaced larger, more sensitive and more cumbersome devices. The earliest drives were usable only in the protected environment of a data center. Later generations progressively reached factories, offices and homes, eventually reaching ubiquity.

Disk media diameter was nominally 8 or 14 inches (200 or 360 mm) and were typically mounted in standalone boxes (resembling washing machines) or large equipment rack enclosures. Individual drives often required high-current AC power due to the large motors required to spin the large disks. Hard disk drives were not commonly used with microcomputers until after 1980, when Seagate Technology introduced the ST-506, the first 5.25 inches (133 mm) drive.

The capacity of hard drives has grown exponentially over time. When hard drives became available for personal computers, they offered 5-megabyte capacity. During the mid-1990s the typical hard disk drive for a PC had a capacity of about 1 gigabyte.[6] As of December 2014, desktop hard disk drives typically had a capacity of 500 to 4000 gigabytes, while the largest-capacity drives were 8 terabytes.

1950s–1970s

The IBM 350 Disk File, invented by Reynold Johnson, was introduced in 1956 with the IBM 305 RAMAC computer. This drive had fifty 24 inches (0.61 m) platters, with a total capacity of five million 6-bit characters (3.75 megabytes).[7] A single head assembly having two heads was used for access to all the platters, yielding an average access time of just under 1 second.

The IBM 1301 Disk Storage Unit,[8] announced in 1961, introduced the usage of heads having self-acting air bearings (self-flying heads) with one head per each surface of the disks.

Also in 1961, Bryant Computer Products introduced its 4000 series disk drives. These massive units stood 52 inches (1.3 m) tall, 70 inches (1.8 m) wide, and had up to 26 platters, each 39 inches (0.99 m) in diameter, rotating at up to 1,200 rpm. Access times were from 50 to 205 milliseconds (ms). The drive's total capacity, depending on the number of platters installed, was up to 205,377,600 bytes (205 MB).[9][10]

The first disk drive to use removable media was the IBM 1311 drive. It was introduced in 1962 using the IBM 1316 disk pack to store two million characters. It was followed by the IBM 2311 (1964) 5 megabyte and IBM 2314 (1965) 29 megabyte disk pack HDDs.

Memorex in 1968 shipped the first HDD, the Memorex 630, plug compatible to an IBM model 2311 marking the beginning of independent competition (Plug Compatible Manufacturers or PCMs) for HDDs attached to IBM systems. It was followed in 1969 by the Memorex 660, an IBM 2314 compatible, which was OEM'ed to DEC and resold as the RP02.

In 1973, IBM introduced the IBM 3340 "Winchester" disk drive, the first significant commercial use of low mass and low load heads with lubricated platters. This technology and its derivatives remained the standard through 2011. Project head Kenneth Haughton named it after the Winchester 30-30 rifle because it was planned to have two 30 MB spindles; however, the actual product shipped with two spindles for data modules of either 35 MB or 70 MB.[11] The name 'Winchester' and some derivatives are still common in some non-English speaking countries to generally refer to any hard disks (e.g. Hungary, Russia).

Also in 1973, Control Data Corporation introduced the first of its series of SMD disk drives using conventional disk pack technology. The SMD family became the predominant disk drive in the minicomputer market into the 1980s.

During the 1970s, captive production, dominated by IBM's production for its own use, remained the largest revenue channel for HDDs, though the relative importance of the OEM channel grew. Led by Control Data, Diablo Systems, CalComp and Memorex, the OEM segment reached $631 million in 1979, but still well below the $2.8 billion associated with captive production.[12]

1980s, the PC era

As the 1980s began, hard disk drives were a rare and very expensive optional feature on personal computers (PCs); however by the late '80s, hard disk drives were standard on all but the cheapest PC.

Most hard disk drives in the early 1980s were sold to PC end users by systems integrators such as the Corvus Disk System or the systems manufacturer such as the Apple ProFile. The IBM PC XT in 1983, included an internal standard 10MB hard disk drive, and soon thereafter internal hard disk drives proliferated on personal computers.

Diagram of HDD manufacturer consolidation

As of December 2011, virtually all of the world's HDDs were manufactured by three large companies: Seagate,[46] Western Digital, and Toshiba. Hitachi (HGST) was acquired by Western Digital in 2012.[47]

The market has continued to consolidate since the 1980s as dozens of manufacturers exited or were acquired. The first notable casualty in the PC era was Computer Memories Inc. or CMI; after an incident with faulty 20MB AT disks in 1985,[48] CMI's reputation never recovered, and they exited the HDD business in 1987. Another notable failure was MiniScribe, which went bankrupt in 1990 after it was found that they had engaged in accounting fraud and inflated sales numbers for several years. Many other companies (like Kalok, Microscience, LaPine, Areal, Priam, and PrairieTek) also did not survive the shakeout, and had disappeared by 1993; Micropolis was able to hold on until 1997, and JTS, a relative latecomer, lasted only a few years and was gone by 1999, after attempting to manufacture in India. JTS originated a 3″ form factor for use in laptop computers. Quantum and Integral also invested in the 3″ form factor; but the form factor failed to catch on. Rodime was an important manufacturer during the 1980s, but stopped making disks in the early 1990s to concentrate on technology licensing; they hold a number of patents related to 3.5-inch form factor HDDs.

The following is the genealogy of the remaining participants:

In 2011, based on market research firm IDC, the biggest hard drive makers were Seagate Technology and Western Digital, but the largest national producer was China, followed by Thailand which makes about a quarter of the world's hard drives. The concentration of hard disk drive producers in only a few countries made the supply vulnerable to disruptions like the 2011 Thailand floods.[53]

  48. ↑ Apparently the CMI disks suffered from a higher soft-error rate than IBM's other suppliers (Seagate and MiniScribe) but the bugs in Microsoft's DOS Operating system may have turned these recoverable errors into hard failures. At some point, possibly MS-DOS 3.0, soft errors were reported as disk hard errors and a subsequent Microsoft patch turned soft errors into corrupted memory with unpredictable results ("crashes"). MS-DOS 3.3 apparently resolved this series of problems but by that time it was too late for CMI.
