What is SSD?

Solid State Drive, commonly known as solid state drive, is a hard drive made of an array of solid-state electronic memory chips. It is named because solid capacitors are called Solid in Taiwanese English. SSD consists of a control unit and a storage unit (FLASH chip, DRAM chip).

Solid state drives are exactly the same as ordinary hard drives in terms of interface specifications and definitions, functions and usage methods, and the product appearance and size are also completely consistent with ordinary 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.

The operating temperature range of its chip is very wide, including commercial products (0~70℃) and industrial products (-40~85℃). Although the cost is higher, it is gradually becoming popular in the DIY market. Because solid-state drive technology is different from traditional hard drive technology, many emerging memory manufacturers have emerged.

Manufacturers only need to purchase NAND memory and match it with appropriate control chips to manufacture solid-state drives. The new generation of solid-state drives generally uses SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface.

Solid state storage technology is SSD. Generally, it can be divided into two types. One is flash memory-based SSD: it uses FLASH MEMORY as the storage medium. This is also the most common SSD we usually use, such as the U disks we often use, some electronic memories such as digital cameras and other ATA, Flash Disks with SCSI and FC interfaces are collectively called flash disks.
