What is the maximum capacity of the current computer

Currently, computer hard disk is divided into two kinds of mechanical hard disk and solid state hard disk. The world's largest mechanical hard disk capacity is 16TB, and the largest solid state hard disk capacity is 2TB.

Mechanical hard disk: that is, the traditional ordinary hard disk, mainly by: platters, heads, platters rotary axis and control motors, head controllers, data converters, interfaces, caches, and other parts of the composition. The magnetic head can move along the radius of the platter, coupled with the high-speed rotation of the platter several thousand revolutions per minute, the magnetic head can be positioned in the platter of the specified location for data read and write operations. Information is written to the disk by the electromagnetic flow through the heads that are very close to the magnetic surface, and the information can be read in the opposite way by the electromagnetic flow to change the polarity way.

Solid State Disk: Solid State Disk for short, is a hard disk made with an array of solid-state electronic storage chips, consisting of a control unit and a storage unit. Solid state hard disk in the interface specifications and definitions, functions and methods of use and ordinary hard disk of the exact same, in the product shape and size is also completely consistent with the ordinary hard disk. They are widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, navigation equipment and other fields.
