🚀 Product Overview

The Transcend SSD472K 4TB is not a consumer SSD pretending to be tough—it is purpose-built for industrial, embedded, and mission-critical environments where endurance, temperature tolerance, and data integrity matter more than flashy benchmarks.

Powered by 112-layer 3D NAND and an embedded DDR3 DRAM cache, the SSD472K delivers stable, predictable performance across sustained workloads. Its SATA III interface ensures compatibility across a wide range of systems, while still pushing the limits of the platform with up to 560 MB/s read speeds and enterprise-grade IOPS performance.

Reliability is the real headline. With anti-sulfur protection, dynamic thermal throttling, LDPC ECC, and Power Shield technology, this drive is engineered to survive unstable power, harsh industrial air, and extended temperature extremes. An endurance rating of 9,680 TBW confirms that this SSD is designed for continuous write-heavy operations—not casual storage.

Whether deployed in edge computing, industrial automation, surveillance systems, or embedded platforms, the SSD472K delivers unwavering performance where failure is not an option.
