This is what over half a gigabyte of storage looked like in 1986. The HP 9737 Storage Disk Drive was groundbreaking for its time, offering up to 80 percent less power usage and 150 percent of the speed of its predecessor products while taking up only one-third of the floor space. Two of these units could be placed within a single console for 1.1GB of storage in a unit about the size of a small filing cabinet. The mean time between failures was estimated at more than 70,000 hours.
