In the 1950s, introduction of magnetic tapes and hard disk drives allowed for mass external storage of information, which played the key part of the computer revolution.
[7] Magnetic disk media is today not removable; however disk devices and media such as optical disc drives and optical discs are available both as internal storage and external storage.
[8] As a consequence of rapid development of electronic computers, capability for integration of existing input, output, and storage devices was a determinant factor in their adoption.
[8] IBM 650 was a first mass-produced electronic computer that encompassed wide range of existing in technologies for input-output and memory devices, and it also included tape-to-card and card-to-tape conversion units.
It was originally created to take the place of the DVD format due to its expanded storage capacity.
Memory stick is an integrated circuit designed to serve as a storage and transfer medium for digital data.
It can store data in various form as text, graphics, digital images etc.
Compared to hard disk drives and similar electromechanical disk storage that use moving physical parts to spin a platter or disc, SSDs are typically more compact, quieter, more resistant to physical shock, and have higher input/output rates, lower latency[13] and less power consumption.
