What does ssd mean?

Ssd solid state drive is a computer storage device that mainly uses flash memory as permanent memory.

Solid-state hard disk is a kind of hard disk that uses flash memory chip as storage medium. It has no mechanical structure, so it is more stable and reliable than the traditional mechanical hard disk, with faster reading and writing speed, better seismic performance, less noise, lower calorific value and longer service life.

Ssd solid state hard disk consists of control unit and storage unit. It is widely used in industrial control, video monitoring, network monitoring, network terminals, navigation equipment and many other fields.

The working principle of solid-state hard disk reading data is to record data by using the polarity of specific magnetic particles. When reading data, the magnetic head converts the different polarities of magnetic particles into different electrical pulse signals, and then uses the data converter to turn these original signals into data that can be used by the computer.

Advantages of SSD

1, faster reading and writing.

The reading and writing speed of solid-state hard disk is much faster than that of traditional hard disk, because solid-state hard disk has no mechanical structure and can read and write data directly through flash memory chip, while traditional hard disk needs to read and write data by mechanical means such as rotating reading and writing disk. According to the data, SSD can read and write several times faster than traditional HDD.

2, the seismic performance is better.

Solid state hard disk has no mechanical structure, so it has better seismic performance. Even in the case of severe vibration, it will not affect the security of data, and traditional hard disks are prone to read and write errors due to vibration.

3. Less noise

Traditional hard disks hum when reading and writing data, while solid-state hard disks have no mechanical structure, so there is less noise.
