A⁺ Security Technologies
Elevate Your Data Security Level
As a global leader of industrial-grade memory, ADATA is dedicated to providing solutions not only through durable hardware, but also by using software and firmware. ADATA’s proprietary A⁺ Security data protection technologies are implemented in ADATA industrial-grade flash storage products, including data erase, data encryption 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?
Performing Quick Erase/ Secure Erase
ATA Command – Lock the Drive with a Password
All SATA SSDs support “ATA command,” providing a security mechanism for both User and Master accounts through setting passwords.
Encryption/ Decryption Flow
AES
Encryption/ Decryption
TCG OPAL 2.0
Encryption/ Decryption
Two Methods To Execute Write Protect
Host Software
- Send the vendor command to SSD
- Logs write protection to maintain its validity
- Notify the FTL that the write protection write function is ready
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

How to Choose Industrial SSD for Medical Devices?
Medical devices are rapidly becoming more digital. From medical imaging systems, patient monitoring devices, endoscopy systems, and automated dispensing cabinets to healthcare edge gateways, an increasing number of healthcare applications must continuously record medical images, sensor data, operation logs, alarm events, and system status while supporting diagnostic and treatment workflows.
What Is an NVMe SSD?
Learn what an NVMe SSD is, how NVMe differs from SATA SSDs, and why NVMe storage is ideal for automation, industrial systems, and high-frequency data logging.
What Is ECC DRAM?
Learn what ECC DRAM is, how error correction works, and why it matters for data integrity, system stability, networking security, and mission-critical computing.
How to Choose NVR Storage: Key Factors for Efficient Surveillance Systems
NVR storage is not only about capacity planning. It also affects data integrity and long-term system reliability. For AI NVR and 24/7 recording environments, storage devices must handle heavy write workloads, RAID rebuilding, and continuous recording. As a result, choosing between HDD vs. SSD and selecting the right surveillance SSD have become critical for modern surveillance deployment.
What Is the SSD Temperature Range?
Temperature is the silent limiter of every SSD, and the SSD temperature range is both a performance spec as well as a reliability spec. Under sustained load, NVMe firmware tracks a composite temperature and will start to throttle lightly or heavily. So, write throughput drops hard and latency spikes. Heat also speeds charge leakage inside NAND, which accelerates retention loss. The effect worsens as cells age from program/erase wear. Thus, you burn endurance faster and raise data-retention trouble when the drive later remains unpowered.
Garbage Collection in Industrial SSDs: What You Need to Know
Garbage collection in SSDs is the controller's quiet cleanup job. It compacts still-valid pages into new space and erases blocks that are now mostly junk. That might sound weird until you remember NAND flash can't overwrite a programmed page. It must erase first, and erase happens at the block level, not per page. So, updates become "write elsewhere, then clean later."
