Conner Peripherals

[4] CoData was developing a new type of small hard disk that put the capacity of a 5.25-inch drive into the smaller (and now commonplace) 3.5-inch format.

[4] Conner's drives were notable for eschewing the "tub" type of head-disk assembly, where the disks are inside a large base casting shaped like a square bowl or vault with a flat lid; instead, they preferred the flat base plate approach, which was more resistant to shock and less likely to warp or deform when heated.

[5] Their first drives had the base plate carrying the disks, head arm and actuator enclosed inside a long aluminum cartridge, fixed to a bulkhead on the other side with two screws and sealed with a large, square O-ring.

[5] Conner's 1/3-height (1-inch thick) drives used a domed, cast aluminum lid with four screws, one on each corner, sealed to the base plate with a rubber gasket.

[8] In 1990, Conner Peripherals set a record by reaching $1.337 billion in sales in four years, without acquisitions, making it the fastest-growing manufacturing start-up in United States history.
