Synology SNV5420-800G 800GB Enterprise M.2 2280 NVMe SSD
Estimated delivery between August 10 and August 14.
The Synology SNV5420-800G is an 800GB Enterprise Series M.2 2280 NVMe SSD designed for demanding 24/7 caching workloads in compatible Synology systems, featuring PCIe 3.0 x4 connectivity, sustained read speeds of up to 3,000MB/s, 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 supported 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 provides sustained sequential read speeds of up to 3,000MB/s and sustained sequential write speeds of up to 1,000MB/s.
Sustained random performance reaches up to 400,000 4KB read IOPS and 70,000 4KB write IOPS under Synology’s specified test conditions.
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 data in transit 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 3,000,000-hour MTBF rating and a five-year limited warranty, the SNV5420-800G is designed for sustained enterprise caching workloads in compatible Synology systems.
Compatibility and permitted use depend on the specific Synology system. Confirm support for the SSD and the intended cache or storage-pool 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:
• Synology system model
• Processor and system memory
• DSM version
• Internal M.2 slot or adapter card
• Cache configuration
• Primary storage drives
• RAID configuration
• Workload type
• Queue depth
• Active applications
• Other hardware and software settings
The SNV5420-800G is designed primarily for sustained enterprise caching workloads rather than short consumer benchmark bursts.
Data Protection
End-to-end data protection helps safeguard data integrity across the complete transfer path.
The SNV5420-800G also includes a power-loss protection circuit with dedicated capacitors.
During an abnormal shutdown or power failure, the capacitors provide temporary power so that data in transit can be written safely to NAND flash.
The firmware is designed to support a proper restart when power is restored.
Power-loss protection reduces selected risks but does not replace:
• A suitable uninterruptible power supply
• Synology snapshots
• Independent backups
• Off-site data protection
• A tested disaster-recovery plan
DSM Integration
Synology DiskStation Manager can provide:
• Drive-health monitoring
• Lifetime wear analytics
• Remaining-life information
• Drive-health notifications
• Supported firmware updates
• Advance replacement planning
Lifetime analytics are supported on compatible systems running DSM 6.2.3-25426 or later.
Supported firmware updates through DSM require a compatible system and DSM version.
Compatibility Note
Please confirm that the Synology SNV5420-800G is officially compatible with your exact Synology NAS or SAN system before ordering.
The SSD may be supported through:
• A compatible built-in 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:
• Exact Synology system model
• Hardware revision
• DSM version
• Adapter-card compatibility
• SSD firmware
• Intended cache configuration
• Intended storage-pool configuration
Support for SSD caching or an M.2 storage pool is model-dependent.
A system that supports the SNV5420-800G for SSD caching does not necessarily support using it as an independent storage pool.
The SNV5420-800G is an M.2 2280 NVMe PCIe SSD.
It is not:
• A 2.5-inch SATA SSD
• A 3.5-inch SATA hard drive
• An external USB SSD
• A standard SATA M.2 SSD
• A complete storage system
Available capacity will be lower than the stated 800GB because of storage calculations, formatting, system use and cache configuration.
The five-year limited warranty provides coverage until the warranty period ends or the SSD reaches its rated endurance limit, whichever occurs first.
MTBF is a statistical reliability measurement and is not a guarantee or estimate of the operating life of an individual SSD.
What’s in the Box
• 1 × Synology SNV5420-800G 800GB Enterprise Series M.2 2280 NVMe SSD
A Synology NAS, adapter card, mounting screw and other installation accessories are not included unless specifically stated.
Warranty
Five-Year Synology Limited Hardware Warranty
Sustainability
The Synology SNV5420-800G is RoHS compliant.
Drive-health analytics and remaining-life notifications can help administrators plan replacements before the SSD reaches the end of its supported endurance.
The SSD should be recycled through an appropriate electronic-waste recycling facility at the end of its usable life.
