What does a solid state drive mean? Why is it called solid?

Solid state Drive Definition

Solid state hard drive is not a new product, but many friends are from the mouth of others to understand the relevant knowledge of solid state hard drive, and the white system for the first time with the solid-state understanding of the scene is to install the solid state hard drive system, found that it installed the system boot speed is very fast, only a few seconds of things, so how can mechanical hard drive?
Now whether it is online or physical, their own assembly of computers will basically choose solid state disk as the first. The mechanical hard disk has been slowly made into a storage disk and is treated as a warehouse disk.

So aside from hard drives, what is solid? From the perspective of thermodynamic equilibrium, solid is another form that distinguishes between liquid and gas, characterized by fixed shape and volume, and an important feature is strong electrical conductivity, which is the key point, and its physical characteristics have been a good reflection of why it is called solid.

There is also a saying because the Solid capacitor is called solid in Taiwanese English.
Sum up

From the above paragraphs, you can find several important features of solid state drives:

The first solid state drive is stable, because it is a solid state and has a fixed structure
The second SSD transmission speed is fast, to free ion storage media, to ensure that data protection is not controlled by the power supply, can be adapted to a variety of environments
Third, erase and write more times, not like mechanical hard disk consumption
