Hello everyone, Lin Fei to answer the above questions, what is the meaning of shouting big, what is the meaning of HDD, many people do not know, now let's take a look!
SSD is a solid-state hard drive; it is a mechanical hard disk; the former has no movement structure and is faster to read and write, but is weaker than the latter in terms of price and capacity. In addition, it also has the advantages of low power consumption, good shock and fall resistance, and low calorific value. The following is a detailed description:
1.SSD is solid state disk, or solid state disk for short; it is a mechanical hard disk; the biggest difference between the two is that solid state disk is composed of multiple flash memory particles and main control chip, and there is no mobile structure design, while mechanical hard disk is composed of disk and read / write head.
two。 Fast reading and writing speed of solid state hard disk: flash memory is used as storage medium, and the reading speed is faster than that of mechanical hard disk. The solid-state hard disk does not use a magnetic head, the seek time is almost zero, and the continuous writing speed is high.
3. Solid state hard disk has good shock resistance and fall resistance: the traditional hard disk is disk type, and the data is stored in the disk sector. SSDs are made of flash memory particles (that is, mp3, USB drives, and other storage media), so there are no mechanical parts inside SSDs. In this way, normal use will not be affected even in the case of high-speed movement or even tipping, and the possibility of data loss can be minimized in the case of collision and vibration. Compared with traditional hard drives, solid state drives have absolute advantages.
4.SSD low power consumption: SSD power consumption is lower than traditional HDD solid-state disk noise-free: solid-state disk does not have mechanical motors and fans, working noise value of 0 dB. Solid state disk based on flash memory has low energy consumption and low calorific value in working state (but high-end or high-capacity products consume more energy). There are no mechanical moving parts inside, no mechanical faults, and are not afraid of collision, impact and vibration. Because the solid-state hard disk uses flash memory chip without mechanical parts, it has the characteristics of low heat and fast heat dissipation.
