Additional drives can be connected to a controller to increase the data storage capacity. al. 1983 - MAY. The term later referred to all fixed hard disks because the heads and platters are always encased in the same, sealed unit. Derived from the original specification of a system having two spindles each with a disk capacity of 30 MB, Haughton is reported to have said: "If it's a 30-30, then it must be a Winchester" after the .30-30 Winchester rifle cartridge. Stevens, Louis D. Data Storage on Hard Magnetic Disks in Eric D Daniel, C. Denis Mee, Mark H. Clark, eds. Up until now, in this segment, the two main leaders, Syquest and Ricoh had reached 44 and 50MB respectively. There was no cover to remove during the insertion process. The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology.

As opposed to other solutions, no new drive type or special software was required that impeded adoption, since all that was necessary was an already common USB port. Hard drives continued to become smaller with the launch of the Integra Peripherals 1.8-inch disk in 1991 and the HP Kittyhawk 1.3-inch hard drive in 1992. Both the hard disk drive and floppy . an IBM code name; the designation for a device containing two such disks was 3030 (each disk containing 30 megabytes), the same as the model number of a well-known Winchester rifle] This word is first recorded in the period 1970-75. The term later referred to all fixed hard disks because the heads and platters are always encased in the same, sealed unit. IBM first introduced it as a 8-in diskette in 1971. We used floppy disks and cassettes mostly as paper tape replacements, but we also appreciated and exploited the random access nature of disks. Magnetic Head Development specifications of key IBM models (Retrieved on 1.31.15 from: Harker, J., et. [3] Subsequently there was a period of about 20 years in which other technologies competed with disks in the secondary storage marketplace, for example tape strips, e.g., NCR CRAM, tape cartridges, e.g., IBM 3850, and drums, e.g., Burroughs B430, UNIVAC FASTRAND, but all ultimately were displaced by HDDs. Webopedia focuses on connecting researchers with IT resources that are most helpful for them. She is known for her independent films and documentaries, including one about Alexander Graham Bell. The term Winchester comes from an early type of disk drive developed by IBM that had 30 MB of fixed storage and 30MB of removable storage; so its inventors called it a Winchester in honor of its 30/30 rifle. 1873.
