The hard drive has very interesting history. In the past 30 years it has changed from being a big beast with 2' wide disks capable of holding a few megabytes of data to drives that are 2.5" wide capable of holding terabytes of data storage.
About c. 1950 Engineering Research Associates of Minneapolis built the first storage unit for the U.S. Navy, the ERA 110. It was able to store one million bits of data and retrieve a word in 5 thousandths of a second.
In 1956 IBM created the first computer disk storage system, which could store 5mb of data. It comprised of 50 x 24" wide platters.
By the start of the 1960's IBM had invented the first disk drive with air bearing heads and in 1963 they introduced the removable device.
In the 1970's the 8" drive was produced by IBM.
In 1973 IBM shipped the model 3340 Winchester sealed hard disk drive, the predecessor of all current hard disk drives. The 3340 had two spindles each with a capacity of 30mb.
In 1980, Seagate introduced the first hard disk drive for microcomputers, the ST506. It was a full size 5.25" drive with a stepper motor, and held 5mb of storage.
In 1983 Rodime made the first 3.5" rigid disk drive.
In 1984 the first CD-ROM drives were sold and at the same time the 3.5" IDE drive were developed as a drive connecting to a plug-in expansion board, or "hard card."
In 1997 Seagate produced the first 7,200 RPM, Ultra ATA hard disk drive for desktop computers.
In 2000 IBM tripled the capacity of the world's smallest hard disk drive. The drive capable of holding 1gb of data.
In 2010 disks the size of a match box are openly available to buy from the shops, which are capable of holding greater amounts of data than would have been thought possible 30 years ago.
Who knows what the future of disk technology will be, but you can be sure disks will get smaller, faster and hold much more data than we can imagine today. The important driving force is the IT industry which are producing software and content that requires ever increasing volumes of data and faster access and the drive manufacturers have to keep pace with the increasing demands. The ever developing multimedia technologies and requirements will mean that the humble disk that we all take for granted will be an very important device for a long time to come.
