12-Bay Rackmount NAS for Small Business

The Synology RS2421+ is a 2U 12-bay rackmount NAS designed for small business and remote office deployments. It runs Synology DiskStation Manager and provides file management, sharing and backup services. The unit ships without drives so you can populate the bays with compatible 3.5" or 2.5" SATA HDDs or SSDs.

Suits Teams Needing Expandable File Storage

This system fits organisations that want a diskless platform with four 1GbE ports, two USB 3.2 Gen 1 ports and a PCIe 3.0 x8 slot for adding SSD cache or faster networking. Buyers who require drives included in the box or who need more than 32 GB of DDR4 memory should consider other options.

Quad-Core AMD Ryzen V1500B at 2.2 GHz

The processor delivers four cores at 2.2 GHz with 4 GB of DDR4 installed and a maximum of 32 GB across two slots. This CPU and memory combination determines whether the NAS can handle your workload's concurrent file operations and service demands.

商品問答

How much DDR4 memory can I add to the two slots later?

The RS2421+ supports up to 32 GB total DDR4 across its two memory slots.

Which interface will saturate first when all twelve SATA bays are under heavy RAID load?

The four 1 GbE RJ-45 ports are the first bottleneck under sustained multi-drive RAID traffic.

What are the typical power draw and heat figures when the unit runs 24/7 with drives active?

Expect about 79.56 W during drive access and 34.89 W when the disks are hibernating.
