Synology SNV5420-800G 800GB M.2 NVMe SSD

The Synology SNV5420-800G is an 800GB Enterprise Series M.2 2280 NVMe SSD designed for demanding caching workloads in compatible Synology systems. It features an NVMe PCIe 3.0 x4 interface, sustained sequential speeds of up to 3,000MB/s read and 1,000MB/s write, power-loss protection and endurance rated above 1,400TBW.

Product Description

The Synology SNV5420-800G 800GB Enterprise Series M.2 NVMe SSD is designed to improve I/O responsiveness in compatible Synology NAS and SAN environments.

Built for demanding caching workloads in high-concurrency, 24/7 environments, the SNV5420-800G is suitable for compatible systems used as high-performance file servers, database storage and virtualisation platforms.

The SSD uses an M.2 2280 form factor and NVMe PCIe 3.0 x4 interface. It delivers sustained sequential read speeds of up to 3,000MB/s, sustained sequential write speeds of up to 1,000MB/s, sustained random read performance of up to 400,000 IOPS and sustained random write performance of up to 70,000 IOPS.

End-to-end data protection helps safeguard data integrity throughout the transfer path. The built-in power-loss protection circuit uses dedicated capacitors to help write in-flight data to NAND flash during an unexpected shutdown.

Integration with Synology DiskStation Manager provides drive-health monitoring, lifetime wear analytics, notifications and supported firmware updates through DSM.

With endurance rated above 1,400TBW, a 3 million-hour MTBF rating and a five-year limited warranty, the SNV5420-800G is designed for sustained enterprise caching workloads in compatible Synology systems.

Please note: Compatibility and permitted use depend on the specific Synology system. Confirm support for this SSD and the intended cache or storage configuration before ordering.

Performance Note

Published performance figures represent sustained, steady-state, single-drive results obtained in Synology’s testing environment.

Actual performance may vary depending on the Synology system, processor, memory, DSM version, installed drives, cache configuration, workload and other hardware or software settings.

Compatibility Note

Please confirm that the Synology SNV5420-800G is listed as compatible with your specific Synology NAS or SAN system before ordering.

The SSD may be supported through:

• A compatible internal M.2 NVMe slot
• A compatible Synology E10M20-T1 adapter card
• A compatible Synology M2D20 adapter card
• A compatible Synology M2D18 adapter card

Compatibility depends on the specific Synology model, hardware revision, DSM version, adapter card and intended SSD configuration.

Support for SSD caching or an M.2 storage pool is model-dependent. Do not assume that every compatible Synology system supports both functions.

This is an M.2 2280 NVMe PCIe SSD. It is not a 2.5-inch SATA SSD and cannot be installed in a standard SATA drive bay without a specifically supported interface.

Available capacity will be lower than the stated 800GB because of formatting, system use and storage-capacity calculation methods.

The five-year limited warranty applies until the warranty period ends or the SSD reaches its endurance limit, whichever occurs first.

MTBF is a statistical reliability value and is not a guarantee of the lifespan of an individual SSD.

Recommended Uses

• Compatible Synology SSD cache configurations
• High-performance file servers
• Database workloads
• Virtualisation environments
