Rated for reads up to 3,000 MB/s and writes up to 750 MB/s.
Capacity-specific random I/O
Rated up to 225,000 IOPS random read and 45,000 IOPS random write at 4 KB, QD256.
Enterprise-workload endurance
491 TBW is specified using the JESD219A enterprise workload.
Power-loss protection
The SNV3510 design includes power-loss protection to help safeguard in-flight data.
DSM lifecycle insight
Synology DSM integration can provide workload-based lifetime analytics and streamlined firmware maintenance in validated deployments.
Five-year limited warranty
Coverage applies for five years or until the specified endurance is reached, whichever comes first.
Who is the Synology SNV3510-400G best for?
A strong choice for
- Compatible Synology systems requiring a 400 GB M.2 22110 NVMe SSD
- Demanding cache workloads in 24/7 multi-user environments
- Storage services that benefit from sustained random I/O
- Administrators wanting Synology-validated NVMe media
- Deployments that preserve 3.5-inch bays for primary storage
- Environments where SSD power-loss protection is required
Consider another model if you need
- The target Synology system does not list this exact model and form factor as compatible
- You need a 2.5-inch SATA SSD rather than M.2 NVMe
- You require a capacity other than 400 GB
- You need portable external storage
