Synology SNV3410 400GB M.2 2280 NVMe SSD (SNV3410-400G) – PCIe Gen3 x4, 491 TBW, NAS Cache

NVMe cache built for Synology NAS, with endurance for always-on duty.

The Synology SNV3410-400G is a 400GB M.2 2280 PCIe Gen3 x4 NVMe SSD designed for SSD caching in Synology NAS systems. With up to 3,000MB/s reads, 225K random read IOPS and a 491 TBW endurance rating, it accelerates file access, VMs and databases for small businesses and power users.

Why NAS Caching Needs Purpose-Built NVMe Drives

SSD caching in a NAS absorbs a large share of reads and writes, especially with many users or virtual machines. Consumer NVMe drives may wear out quickly and are not validated with DSM.

The SNV3410 is built and validated by Synology for this role. Its endurance and firmware are tuned for 24/7 caching, and DSM monitors its health and remaining life.

Faster Multi-User and VM Performance

With up to 225K random read IOPS, the SNV3410 cache speeds up file browsing, Synology Photos indexing, virtual machines and databases on supported NAS models.

Seamless DSM Integration

Storage Manager recognizes the drive, reports SSD lifespan and delivers firmware updates, making cache management straightforward.

Setup Instructions

How to Install the Synology SNV3410-400G

1. Check your NAS compatibility list and shut the NAS down.
2. Open the M.2 slot cover (or install a Synology M.2 adapter card).
3. Insert the SSD and secure it with the latch or screw, then close the NAS.
4. In Storage Manager, create a read-only cache (one drive) or read-write cache (two drives in RAID 1).
