In certain situations, users may need to ensure that no unauthorized data is written to an SSD, restricting the drive to read-only mode to protect its internal data from tampering. Apacer's Write Protect feature offers this capability, allowing users to safeguard critical information by completely preventing any write operations.

Write Protect can be activated either through software or hardware. When the SSD is powered on and connected to a host, a specific software command can trigger the firmware to enable Write Protect, blocking all write commands. Alternatively, Write Protect can be engaged via hardware, such as through a GPIO pin on the SSD, providing a flexible solution to meet different security needs.

 

 

In some cases, for better OS compatibility, Apacer’s Virtual Write scheme offers an ideal solution. Rather than writing data into the flash memory, it is instead stored in the volatile RAM portion of the controller. Once the write command is received, the controller will inform the host that the write command has been completed, indicating that the write process is complete. Later, when the system is reset or power turned off, the volatile memory will be gone and no trace of the written data will remain. 
   

 

 

 

Since the Write Protect scheme runs at the device level, it requires no software or driver installation and is fully independent of the host OS. Write Protect will not allow any data to be written to the NAND Flash, meaning that sensitive data will never be overwritten or deleted.
