According to John Robson, this IBM 3380 disk storage unit from 1985~2000 came in many models. It has two hard disk arrays, turning at 3600rpm. Each disk array had two indepant voice coil head assemblies, for a total of 4. The capacity of each axcess was about 2gb or 8gb for the whole box. The box weighed about 300 pounds, was 4' wide x 3' deep, and 6' high. Many boxes could be strung together. In a large computer complex there were whole rooms that were only rows and rows of them, giving rise to the term disk farms.
