What does A⁺ Security include ?

How To Do Secure Erase？

ATA Command – Lock the Drive by Password

All SATA SSDs support “ATA command”, providing a security mechanism for both User and Master accounts by setting passwords.

The Encryption/ Decryption Flow

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
