It is named after Taiwan Province Province, and its English name is solid capacitor. SSD consists of control unit and storage unit (FLASH chip, DRAM chip).
Solid-state hard disks are completely the same as ordinary hard disks in interface specifications and definitions, functions and usage methods, and basically the same in product appearance and size (the emerging solid-state hard disks in U.2 and M.2 forms are completely different from SATA mechanical hard disks in size and shape).
Widely used in military, vehicle, industrial control, video monitoring, network monitoring, network terminals, electric power, medical care, aviation, navigation equipment and many other fields.
The working temperature range of the chip is very wide, from 0~70℃ for commercial products to -40~85℃ for industrial products. Although the cost is high, it is spreading to DIY market.
Because the technology of solid-state hard disk is different from traditional hard disk, there are many emerging memory manufacturers. Manufacturers only need to buy NAND particles, match the appropriate control chip, and write the main controller code, so they can manufacture solid-state hard disks.
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 are widely used in the new generation of solid state drives.
