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.
