Note: Upgrade DSM to version 7.2.2-72806 and onward before installing this drive (only applicable to models with DSM).

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.
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 random 4K reads up to 660,000 IOPS and random 4K writers up to 120,000 IOPS across the usable lifespan of the drive, while an endurance (TBW) of up to 2900TB ensures longevity.
Data Integrity Safeguards
The SNV5400 series offers 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, including the workload placed on them over time.
Timely Notifications
Timely notifications of potential issues help you plan ahead to attain consistent system performance and longevity.
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 their 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.
