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

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 small white system with solid state understanding for the first time is to install the solid state hard drive system, found it installed good system boot speed is very fast, only a few seconds of things, so how can mechanical hard drive?
Now, whether online or physical, their own computer will choose solid-state drives as the first choice. And mechanical hard drives have been slowly made into storage disks and treated as warehouse disks.

So what is a solid, aside from a hard disk? In thermodynamic equilibrium, a solid is another form that distinguishes a liquid from a gas, and it has a fixed shape and volume, and another important characteristic is that it is electrically conductive, which brings me to the point, and its physical characteristics are very good for why it's called a solid.

Another is that the Solid capacitor is called solid in Taiwanese English.

Some important features of solid-state drives are:

First, solid state disk is stable, because it is solid state, has a fixed structure
Second solid state drive transmission speed, to free ion storage media, to ensure data protection from power control, can be adapted to a variety of environments
Third erase times, not like mechanical hard disk consumption
