Synology SNV3410 400 GB Enterprise Series M.2 NVMe SSD
A 400 GB enterprise M.2 2280 NVMe SSD (PCIe 3.0 x4) validated as a read cache for Synology NAS, rated at 3,000 MB/s sequential reads and 491 TBW.
Why people pick it
- 3,000 MB/s sequential reads make it a fast read cache over HDD arrays
- Validated by Synology for its own NAS and adapter cards
- Lifetime analytics and one-click firmware updates through DSM
- Compact M.2 2280 format leaves drive bays free
Know before you buy
- 400 GB holds only a partial working set of a large media library
- 491 TBW endurance suits caching rather than constant heavy writes
- SNV3400-series drives lack the power-loss capacitors of the SNV3500/SNV5400 series
