Use Case
The Transcend SSD452K is a cost-optimised 2.5-inch SATA III industrial SSD used in factory automation controllers, kiosks, digital signage, POS terminals and legacy embedded platforms that still boot from SATA. The DRAM cache and 3K P/E 3D TLC NAND keep write latency predictable for logging and database workloads.
