Which is better, solid state hard disk or traditional hard disk?

The computer hard disks used now are basically solid-state hard disks. When the system is running, the reading and writing speed will be accelerated. The reading and writing speed of mechanical hard disk is slower than that of solid-state hard disk, but the data stored in mechanical hard disk is more stable.

Solid-state hard disk is a hard disk made of solid-state electronic memory chip array, which consists of control unit and memory unit (FLASH chip, DRAM chip). Mechanical hard disk is a traditional common hard disk, which is mainly composed of disk, magnetic head, disk spindle, control motor, magnetic head controller, data converter, interface and cache.

Compared with traditional hard disk:

The interface specification, definition, function and usage of solid state hard disk are almost the same as those of ordinary hard disk, and the shape and size are basically the same as those of ordinary 2.5-inch hard disk.

Solid-state hard disk has the characteristics of fast reading and writing speed, light weight, low energy consumption and small size that traditional mechanical hard disk does not have, and its shortcomings are also obvious. Although IDC believes that SSD has entered the mainstream of the storage market, the price is still relatively expensive and the capacity is low. Once the hardware is damaged, it is difficult to recover the data. And some people think that SSD's durability (life) is relatively short.
