Persistent Storage Handler: Storage Capacity 64GB-1TB

Component Specifications

Definition

A specialized industrial component designed to manage, store, and retrieve audit log data with high reliability, ensuring data persistence across power cycles and system failures. It implements error correction, wear leveling, and data integrity verification mechanisms suitable for continuous operation in manufacturing environments.

Working Principle

Utilizes flash memory technology with a controller that manages data writing, reading, and retention through wear-leveling algorithms, error correction codes (ECC), and bad block management. Implements write-ahead logging and atomic operations to prevent data corruption during unexpected shutdowns.

Materials

PCB with industrial-grade NAND flash memory chips, controller IC (ARM Cortex or equivalent), capacitors for power loss protection, conformal coating for environmental protection.
