Purpose-built cache SSD

The Synology SNV3410-400G is an M.2 2280 NVMe drive designed specifically for Synology NAS units with built-in M.2 slots. It functions as a high-speed read-write cache to accelerate I/O-heavy applications and multi-user workloads. Tight DSM integration provides automatic firmware updates and health analytics without extra tooling.

400 GB capacity and 1 022 TBW endurance

The 400 GB drive delivers up to 3 000 MBps sequential read and 750 MBps sequential write, with sustained 4K random performance of 400 000 read and 70 000 write IOPS. It is rated for 1 022 TBW, giving ample headroom for 24/7 caching in demanding environments. Write-heavy workloads will exhaust endurance faster than read-dominated ones.

Gen3 x4 interface and DSM-managed reliability

The PCIe 3.0 x4 connection fits any M.2 2280 slot wired for NVMe, drawing 1.6 W idle and 3.5 W active. End-to-end data protection guards integrity across the data path. DSM surfaces actionable insight on wear and performance, so administrators can plan replacements before service disruption occurs.
