A basic introduction to solid state drives
Jul 15, 2022| Solid-state drives are named after solid capacitors are called Solid in Taiwanese English. SSD consists of control unit and storage unit (FLASH chip, DRAM chip).
The specification and definition of the interface, function and usage of the solid state drive are exactly the same as those of the ordinary hard drive, and the product shape and size are basically the same as those of the ordinary hard drive (the emerging U.2, M.2 and other forms of solid state drive size and shape Completely different from SATA mechanical hard drives).
It is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminal, electric power, medical, aviation, navigation equipment and many other fields.
The chip has a wide operating temperature range, commercial products (0~70℃) and industrial products (-40~85℃). Although the cost is higher, it is spreading to the DIY market.
Since the technology of solid-state drives is different from that of traditional hard drives, many emerging memory manufacturers have emerged. Manufacturers only need to buy NAND particles, configure appropriate control chips, and write the main controller code to manufacture solid-state drives.
The new generation of solid-state drives generally use SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, M.2 interface, CFast interface, SFF-8639 interface and NVME/AHCI protocol.
