Synology SNV3410-400G M.2 NVMe SSD 400GB PCIe 3.0 x4

Overview

The Synology SNV3410-400G is a NAS-validated M.2 NVMe solid-state drive designed specifically for SSD caching workloads within Synology storage systems. It is deployed by storage administrators and infrastructure engineers who need to reduce storage latency and improve random I/O performance in multi-user NAS environments. The drive is optimized for continuous 24/7 operation and integrates directly with Synology DiskStation Manager (DSM) to monitor endurance, health status, and cache workload analytics.

From a hardware perspective, the SNV3410-400G uses a PCIe 3.0 x4 NVMe interface in an M.2 2280 form factor, delivering sustained sequential read throughput up to 3,000 MB/s and sequential write throughput up to 750 MB/s. For random workloads typical of NAS caching, the drive supports up to 225,000 IOPS random reads and 45,000 IOPS random writes with a queue depth of 256 using 4 KB blocks. The endurance rating of 491 TBW and a mean time between failures of approximately 1.8 million hours target sustained caching workloads where write amplification and continuous access are expected.

In deployment terms, the drive typically operates inside NAS units equipped with integrated M.2 slots or via Synology PCIe expansion cards such as M.2 adapter modules. The SNV3410 series is commonly used in branch offices, edge storage nodes, virtualization hosts using NAS backends, and departmental file servers where large HDD arrays benefit from SSD-based cache acceleration. Its compact M.2 format allows installation without consuming front drive bays, preserving primary storage capacity in rack or tower NAS systems.

The device integrates directly with the Synology DSM management ecosystem. Administrators can track endurance consumption, temperature, and estimated lifespan through the Storage Manager interface. DSM also supports read-only or read-write SSD caching configurations and can mirror two NVMe drives in RAID 1 to maintain cache integrity in the event of SSD failure.

A practical deployment example is a NAS supporting virtualization workloads where HDD arrays experience high metadata and small-file access latency. Installing two SNV3410-400G drives in mirrored cache mode significantly reduces response time for frequently accessed blocks such as VM images, database indexes, and container layers.

This device is not intended for use as a general-purpose primary storage volume in most deployments. It is optimized specifically for SSD cache acceleration within compatible Synology systems. Environments requiring persistent NVMe storage pools or extremely write-intensive workloads may require NVMe SSD models designed for full storage pool operation or higher endurance ratings.
