Two-to-four 3340 drives could be attached to the IBM System/370 Model 115 processor -- which had been announced concurrently with the 3340 -- providing a storage capacity of up to 280 million bytes. In 2003, the first serial ATA drive was produced by Seagate. This utility should be used whenever you move your Desktop Computer, even a short distance. Introduced in 1973 as the model 3340, the drive had one permanent and one removable spindle, each holding 30MB. The name arose because the original 1973 engineering prototype for what later became the IBM 3340 featured two 30-megabyte volumes; 30--30 became "Winchester" when somebody noticed the similarity to the common term for a famous Winchester rifle (in the . The work at BSL was largely inspired by the late Rudolph Langer, who improved significantly on Hornbuckle's model. The Seagate company was founded in 1979 and IBM introduced its Piccolo drive, storing 64MB over eight disks.

The disks also had a 30 ms access time, and lubricated coating allowing the heads to remain in contact with the surface when rotation speed changes.
What Is a Hard Disk Drive? | PCRS COMPUTERS Because of this 30/30 configuration, the code name Winchester was selected after the famous Winchester .30-30 rifle; subsequently the capacities were increased, but the code name stuck. [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.

Introduced in 1980 by Seagate Technology It stores up to 5 megabytes after formatting and cost $1500 The term Winchester was originally used by IBM as a code name for the 3340 disk model prior to its announcement.
What is the historical timeline for Winchester firearms? Memorex shipped the first HDD, the Memorex 630, in 1968, plug compatible to an IBM model 2311 marking the beginning of independent competition (Plug Compatible Manufacturers or PCMs) for HDDs attached to IBM systems. 1974 - IBM 62GV Gulliver, introduced the Swinging Arm Actuator, adopted for all HDD in the 1980s. The disk drive consists of one or more platters and heads, and the control mechanism with its associated electronics. The Rise of Plug-Compatible Equipment Manufacturers .

Updates? This advance meant that the heads could be kept closer to the platters, increasing storage density. The Winchester technology allowed the head to land and take off from the disk media as the disk spun up and down. Computer data was written to and read from the disk's surface.
