Built for 24/7 Performance
The SNV5420-800G is part of Synology's Enterprise Series M.2 NVMe SSD line, specifically designed for continuous operation in business-critical environments. Whether deployed as an SSD cache to accelerate read/write operations for frequently accessed files or as a storage pool tier for transactional databases, this drive delivers consistent, sustained throughput under heavy concurrent loads.
Advanced Data Integrity
The SNV5400 Series offers full end-to-end data protection, including power loss protection with capacitors in their circuits to safely write cached data to NAND flash memory during power failures, preventing data loss in unexpected shutdown scenarios. Combined with an uncorrectable bit error rate (UBER) of less than 1 sector per 1017 bits read, this SSD provides enterprise-level reliability.
Seamless Synology Integration
Designed exclusively for Synology NAS models, including DS1522+, DS1821+, and DS920+, the SNV5420-800G integrates seamlessly with DSM software. The drive supports advanced health monitoring, lifetime analytics, one-click firmware updates, and automatic detection—simplifying administration and reducing configuration risks.
Ideal Use Cases
-
SSD Caching: Accelerate random I/O responsiveness for multi-user file servers and shared storage
-
Database Storage: Provide fast, reliable storage for SQL databases, virtual machines, and containerised applications
-
Tiered Storage: Deploy as a hot storage layer for performance-critical data alongside HDD capacity tiers
-
Virtualisation: Support high-IOPS workloads for VMware, Hyper-V, and Virtual Machine Manager environments
