All-in-One Efficiency. Secure and Stable Edge Performance — Meet the PT25R-Pi HAT SSD

Apacer’s PT25R-Pi HAT SSD is an integrated, all-in-one HAT solution with a built-in PCIe SSD, purpose-built to meet the growing demand for cost-effective Raspberry Pi* 5–based systems. Designed as a Hardware Attached on Top (HAT) module, it connects directly to the 40-pin GPIO header and supports PCIe Gen3 x1, delivering low-latency performance. By eliminating the need for additional adapters, external enclosures, or separate storage devices, the PT25R-Pi HAT SSD reduces system complexity and assembly time. This streamlined architecture is particularly valuable for educational platforms, distributed retail terminals, and large-scale IoT deployments.

What differentiates the PT25R-Pi HAT SSD is Apacer’s exclusive CoreSnapshot 2 technology—a patented real-time backup and recovery mechanism. It enables rapid system backup and restoration without time-consuming data transfer procedures, allowing systems to resume operation quickly and minimizing downtime in mission-critical environments.

Engineered for stable and secure edge applications, the PT25R-Pi HAT SSD integrates comprehensive protection and optimization technologies:

CoreSnapshot 2 Technology: Real-time backup and rapid system restoration to ensure operational continuity.
End-to-End Data Protection: Safeguards data integrity across the entire transmission path.
Hardware AES Encryption: Delivers robust data security against unauthorized access.
Thermal Monitoring & Throttling: A built-in thermal sensor (via S.M.A.R.T.) dynamically regulates performance to maintain safe operating temperatures.
Sidefill Technology: Enhances structural integrity to withstand vibration, shock, and thermal stress in industrial environments.

To ensure sustained endurance and power efficiency, the PT25R-Pi HAT SSD incorporates advanced flash management technologies:

LDPC ECC & On-Module ECC: Strengthen error correction capability to improve data accuracy and extend service life.
Wear Leveling & Bad Block Management: Optimize NAND utilization and maintain long-term reliability.
Optimized Power Management: Enables low latency, high data throughput, and reduced power consumption.

Featuring a compact, all-in-one HAT with a built-in PCIe SSD design, the PT25R-Pi HAT SSD significantly reduces system footprint, assembly complexity, and overall hardware costs—making it an ideal Raspberry Pi* 5–compatible solution for compact, space-constrained edge AI systems that demand fast deployment times, consistent performance, and long-term operational durability.
