When did SSDs come into existence, please?

Solid State Drives were available in 1956, when IBM invented the world's first hard disk.

Solid State Drive (SolidStateDisk or SolidStateDrive, abbreviated as SSD), commonly known as solid state hard disk, solid state hard disk is made with an array of solid state electronic storage chips and hard disk, because the solid capacitors in Taiwan English called Solid and named. SSD by the control unit and storage unit (FLASH chip, DRAM chips). Solid state hard disk in the interface specifications and definitions, functions and methods of use and ordinary hard disk is identical, in the product shape and size is also completely consistent with the ordinary hard disk. It is widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, power, medical, aviation, navigation equipment and many other fields.

The operating temperature range of its chips is wide, and it is gradually popularizing to the DIY market despite its high cost. Because SSD technology is different from traditional hard disk technology, it has given rise to a number of emerging memory manufacturers. Manufacturers can build SSDs by simply purchasing NAND memory and matching it with an appropriate control chip. The new generation of SSDs commonly use SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface, SFF-8639 interface and M.2NVME/SATA protocol.
