Synology SNV5420-1600G 1600GB Enterprise M.2 NVMe SSD for NAS Caching

The Synology SNV5420-1600G is a 1600GB M.2 2280 NVMe PCIe 3.0 x4 enterprise SSD purpose-built to accelerate Synology NAS and SAN systems, delivering up to 660,000 random read IOPS and sustained sequential read speeds of 3,000 MB/s for consistently fast performance in 24/7 environments.

Ideal for IT professionals, enterprise storage administrators, and businesses running high-performance file servers, database workloads, virtualization platforms, and containerized deployments who need a cost-effective, in-place performance upgrade for existing Synology NAS systems using Synology DiskStation Manager (DSM).

The SNV5420-1600G is backed by a 5-year Synology warranty and features full end-to-end data integrity protection including power loss protection with onboard capacitors. Firmware updates are delivered automatically through DSM, and Synology's integrated analytics tools provide actionable insight for long-term performance and longevity monitoring.

Key Features of the Synology SNV5420-1600G

• Purpose-Built for Synology NAS: Designed to integrate intelligently with Synology DSM to accelerate I/O performance on DiskStation and RackStation systems via internal M.2 slots, E10M20-T1, M2D20, and M2D18 expansion cards.
• High-Performance Caching: Up to 660,000 / 120,000 sustained 4K random read/write IOPS (QD256) and 3,000 / 1,000 MB/s sequential read/write speeds maintain consistent throughput across the drive's usable lifespan.
• Exceptional Endurance: Rated for over 2,900 TBW (calculated per JESD219A enterprise workload), making it suitable for write-intensive caching applications in always-on environments.
• Power Loss Protection: Onboard capacitors in the power loss protection circuit safely flush cached data to NAND flash during unexpected shutdowns, preserving data integrity.
• End-to-End Data Protection: Full data path integrity safeguards from host to flash ensure data consistency under demanding enterprise workloads.
• Automatic Firmware Updates: Seamless firmware management through Synology DSM eliminates manual update workflows and keeps the drive optimized over time.
• Low Power Consumption: Draws only 5 W during active read and 5.5 W during active write, with a 2.5 W idle state to minimize operational energy costs.
• Wide Operating Temperature Range: Rated 0 degrees C to 85 degrees C operating temperature supports deployment in demanding server environments.
