Synology SAT5221-480G 480GB 2.5" SATA SSD

The Synology SAT5221-480G is an enterprise-grade solid-state drive designed for 24/7 operation within network-attached storage environments. This model utilizes Kioxia 112-layer 3D TLC NAND flash memory to provide stable storage for professional server workloads. It is engineered specifically for Synology systems to maintain high I/O performance and low latency during multi-user access. The drive is built for enterprise environments where long-term reliability is prioritized for tasks like virtualization and database hosting.

Data integrity is managed through hardware-integrated end-to-end data protection and Error Correction Code technology. To prevent potential data corruption during sudden power interruptions, the unit includes dedicated power loss protection circuitry. It carries an endurance rating of 11,460 TBW and a mean time between failures of 1.5 million hours. The 7mm height ensures physical compatibility with standard internal drive bays in both rackmount and desktop server enclosures. This specialized hardware design minimizes the risk of drive failure in demanding mixed-workload scenarios.
