1. A solid state drive is a hard disk made with an array of solid-state electronic memory chips.
Solid state hard disk consists of control unit and storage unit (FLASH chip, DRAM chip). Solid state hard disk in the interface specifications and definitions, functions and methods of use and ordinary hard disk is identical, in the product shape and size is also completely consistent with the ordinary hard disk. It is widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and many other fields.
2. Liquid hard disk is a hard disk that uses common liquid to store electronic data.
Researchers have recently discovered a liquid method of storing data - "colloidal clusters", scientists are able to use "wet computing processing technology" (a technology that enables images Scientists were able to use "wet-body computational processing" (a technique that allows images, videos and other documents to be stored in particles suspended in water) to store information in "colloidal clusters," which are placed in liquids that can change state. According to the researchers, the state change of the particles is equivalent to the 1 and 0 data encoding of solid-state hard disk technology.

Advantages of Solid State Drives:
1. Fast read and write speeds:
Using flash memory as the storage medium, read speeds are faster relative to mechanical hard drives. Solid state drives can easily reach 0.1 milliseconds or even lower.
2, shock resistance:
Solid state hard disk is made using flash memory particles (i.e., mp3, U disk and other storage media), so the SSD solid state hard disk does not have any
mechanical parts inside, so that even in the case of high-speed movement or even accompanied by flipping tilt will not affect the normal use of the case, and in the case of bumping
collision and vibration
Minimizing the possibility of data loss in the event of a crash or shock.
3. Low power consumption:
Solid state drives consume less power than traditional hard drives.
4, no noise: solid state drives do not have mechanical motors and fans, working noise value of 0 decibels.
5, the working temperature range is large: and most of the solid state hard disk can work in -10 ~ 70 degrees Celsius.
6, lightweight: SSDs are lighter in weight, 20-30 grams lighter compared to regular 1.8-inch hard drives.
