How is info read from SSD?
Inside the SSD are five main parts. These are controller, NAND flash memory, SATA interface, SSD PCB and card (circuit board). The information is travelling from the SSD to the computer through a standard SATA connection. Inside the SSD the controller is an embedded processor that bridges flash memory components to the host (such as a computer).
The controller executes codes provided by the SSD's firmware (a mini operating system) to full-fill the data requests from the host. The information is stored and red with zeros and ones. The memory cells store voltage and can be either an on (1) or off (0), which allows them to store data in binary form.
