In 1962, IBM introduced its model 1311 disk, which used six 14-inch (nominal size) platters in a removable pack and was roughly the size of a washing machine. This became a standard platter size and drive form-factor for many years, used also by other manufacturers. The IBM 2314 used platters of the same size in an eleven-high pack and ...
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc , and usually weighs less than 30 g (1 oz).
USB flash drive: Various USB 1.1/2.0/3.0/3.1 2000/2001 8 TB [10] (not to scale) Universally compatible across most non-mobile computer platforms, their greater size suits them better to file transfer/storage instead of use in portable devices

Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [1] [2] Drums were widely used in the 1950s and into the 1960s as computer memory. Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. [3]
The SpecDrum was an 8-voice machine (i.e. it allowed the user to load 8 different percussion samples). However it only had 3 output channels (i.e. maximum polyphony of 3 samples at a time) - the first channel could trigger the 'bass drum' voice, the second channel was used for the three snare/tom voices, and the third channel for the remaining ...
At the time of their introduction the storage capacity exceeded any other random access mass storage disk or drum. There were three models of FASTRAND drives: FASTRAND I had a single drum. The large mass of the rotating drum caused gyroscopic precession of the unit, making it tend to spin on the computer room floor as the Earth rotated under it ...
The IBM 2301 is a magnetic drum storage device introduced in the late 1960s to "provide large capacity, direct access storage for IBM System/360 Models 65, 67, 75, or 85." The vertically mounted drum rotates at around 3,500 revolutions per minute, and has a head-per-track access mechanism and a capacity of 4 MB.
