SNV5420-400G | Synology Inc.

Supercharge your NAS/SAN

Enterprise Series M.2 NVMe SSDs are designed to intelligently work with Synology DiskStation Manager (DSM) to boost I/O performance. These high-performance NVMe drives accelerate the slower but higher-capacity storage space provided by traditional hard drives, enabling cost-effective, in-place upgrades for existing systems.

PerformanceUp to 120,000 4K random write IOPS

EnduranceUp to 2,900 TBW

AnalyticsActionable insight for optimal performance and longevity

UpdatesAutomatic firmware updates with DSM

Consistently fast caching for 24/7 environments

Designed specifically for Synology systems, Enterprise Series M.2 NVMe SSDs are built for maximum performance consistency. Each drive is rated for up to 660,000/120,000 4K random read/write IOPS across the usable lifespan of the drive. Endurance of up to 2,900 TBW ensures longevity.

Data integrity safeguards

The SNV3500 and SNV5400 Series offer full end-to-end data protection, including power loss protection to ensure data integrity during unexpected shutdowns. These series have capacitors in their power loss protection circuits to safely write cached data to NAND flash memory during power failures, thus preventing data loss.

Better analytics

Synology drives can provide more accurate insights about drive health in Synology DSM, taking into consideration the workload placed on them over time.

Timely notifications

Plan further ahead for uninterrupted system performance and longevity with timely notifications.

Optimal use

Easy monitoring allows you to make optimal use of each SSD.

Effortless firmware updates

Synology DSM keeps your drives up to date automatically. No need for separate maintenance sessions.

Purpose-built for Synology NAS

Synology Enterprise Series M.2 NVMe SSDs undergo comprehensive validation for use in our systems after every engineering change. Firmware and components are rigorously controlled, while extensive I/O stress, power cycling, and temperature testing ensure that all products meet the highest standards of quality and reliability.
