A⁺ Security

As a global leader of industrial-grade memory, ADATA is dedicated to provide solutions for industries not only by durable hardware, but also by software and firmware. ADATA’s proprietary A Security data protection technologies are implemented in ADATA industrial-grade flash storage products, including data erasedata encryptiondestruction, and write protect. These can be widely used in various industrial applications to elevate data security. With A Security, confidential data can be effectively protected from being leaked or tampered with.

What does A Security include ?

Data Erase/ Destruction

- Quick Erase: Erases the mapping table in 1 second

- Secure Erase: Erases data in every corner by ATA command

- Military Erase: Meets the Military-grade and overwrites data

- Destruction: Destroys firmware and SSD can’t operate normally

Data Encryption

- AES 256-bit:Encrypts data with AES 256-bit key

(*Controllers with AES hardware support)

- TCG OPAL 2.0: Meets TCG Protocol

Write Protect

Can be set through hardware or software

How To Do Quick Erase/ 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
