The significance of this product, and the reason that disk drives in general became known as "Winchester technology" had nothing to do with the configuration of the product. Hard drives are beginning to be replaced with solid sate drives in some laptops due to their higher speed and increased durability. Al Shugart identified this new Winchester head as one of the four most significant developments in mass storage. After the Winchester, lubricated coating became the standard for mechanical hard drive development. HDDs continued to get smaller with the introduction of the 3.5-inch form factor by Rodime in 1983 and the 2.5-inch form factor by PrairieTek in 1988. 80 half-pages [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.
