Two Methods To Execute Write Protect
By Software - By settings in software and firmware
Host Software
- Send the vendor command to SSD
- Logs the write protection to maintain its validity
- Notify the FTL that the write protection write function is ready
By Hardware - By turning on the hardware switch
The SSD PCB Features One Hardware Switch
- Connect to the GPIO pin on the SSD controller
- Detect the GPIO pin signal
- Notify the FTL that the write protection write function is ready
