Internal M.2 NVMe SSD SYNOLOGY SNV5420-1600G — 1.6 TB, PCIe 4.0, 3000 MB/s read, 1000 MB/s write

The SYNOLOGY SNV5420-1600G is an internal M.2 NVMe SSD with 1.6 TB capacity and PCIe 4.0 interface, designed as a component for NAS systems. It provides up to 3000 MB/s sequential read and 1000 MB/s sequential write speeds and is intended to accelerate caching and improve I/O performance for storage pools, virtual machines, databases and backup workloads.

Advantages

The drive offers consistently high random read/write performance, rated up to 660,000/120,000 4K IOPS throughout its usable life, and endurance up to 2,900 TBW for sustained service. Built-in NVMe protocol and PCIe 4.0 interface deliver low latency and high bandwidth, while power-loss protection and end-to-end data protection features help preserve data integrity during unexpected shutdowns.

Suitable for

• NAS caching to accelerate slower high-capacity HDD storage
• Storage for virtual machines and container workloads
• Database acceleration and high I/O applications
• Backup pools and read/write intensive cache layers

Key specifications

• Capacity: 1.6 TB (1600 GB)
• Form factor: M.2
• Interface: PCIe 4.0, NVMe
• Sequential read: up to 3000 MB/s
• Sequential write: up to 1000 MB/s
• Random 4K performance: up to 660,000 IOPS (read) / 120,000 IOPS (write)
• Endurance: up to 2,900 TBW

How to use

Install the SNV5420-1600G into a compatible M.2 slot on your NAS or host system following the manufacturer’s mounting instructions. Configure the drive in your NAS operating system (for example Synology DSM) as an SSD cache or an internal volume according to your needs. Use proper formatting and allocate the drive to caching or storage pools through the storage management interface, then monitor health and SMART attributes regularly.

Recommendations

For optimal performance and longevity, use the SNV5420-1600G as an SSD cache in front of high-capacity HDD pools or for workloads with high random I/O. Ensure your NAS firmware/DSM is up to date and enable power-loss protection features where available. Monitor drive endurance and replace the drive before TBW limits are reached for uninterrupted service.
