Solid State Disk or Solid State Drive, referred to as SSD, also known as solid-state drive, is a hard drive made of an array of solid-state electronic storage chips.
Solid-state drives are exactly the same as ordinary hard drives in terms of interface specifications and definitions, functions and usage methods, and their product appearance and size are basically the same as ordinary hard drives (emerging U.2, M.2, etc. The size and shape of solid-state drives are completely different from SATA mechanical hard drives).
It is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and many other fields.
Advantages
Fast reading and writing speed: Flash memory is used as the storage medium, and the reading speed is faster than that of mechanical hard disks. SSDs do not use magnetic heads and their seek time is almost zero. The continuous writing speed is very amazing. Most solid-state drive manufacturers will claim that their solid-state drives have a continuous reading and writing speed of more than 500MB/s. In recent years, NVMe solid-state drives can reach around 2000MB/s, or even more than 4000MB/s.
Shock and drop resistance: Traditional hard drives are disk-type, and data is stored in disk sectors. SSDs are made of flash memory particles (i.e. MP3, U disk and other storage media), so there are no mechanical parts inside the SSD solid state drive, so even when moving at high speed or even with flipping and tilting, it will not affect normal operation. use.
Low power consumption: The power consumption of solid-state drives is lower than that of traditional hard drives.
