Synology 4-Bay DiskStation DS425+ (Diskless)

Extra speed when you need it

What's different?

Synology DS425+ is a solid 4-bay NAS that's perfect for home offices, small businesses and content creators who need reliable storage without the complexity of enterprise systems. The standout feature is its 2.5GbE networking

which delivers noticeably faster file transfers and backups compared to the previous generation of 1GbE models.

Pair DS425+ with a Synology router (RT6600ax or WRX560) to maximize the 2.5GbE connectivity. Enjoy high-speed transfers and secure your network with VLANs, threat prevention and web filtering — all through a Synology interface that you can securely access and manage from anywhere.

When SSD cache makes perfect sense

Utilize M.2 NVMe SSDs to create an SSD cache when your workload involves frequent access to small, random files or repeated read/write operations.

• Deploying multiple containers
• Scrolling through large photo collections
• Running a file server with relatively small files accessed concurrently

When you need more speed

Utilize SATA 2.5" SSDs for primary storage when you need hot-swappable capability in situations where uptime is essential, such as database storage.

• Enable remote access to your files or keep everything local and offline
• Improve efficiency by adding SNV3000 or SNV5000 series M.2 SSDs without sacrificing a drive bay
• Back up all of your data with built-in tools, including PC, Mac, mobile devices and cloud data
• Deploy a hybrid cloud to scale storage capacity seamlessly via Synology C2 cloud
• Synchronize files across locations and devices automatically
