Purpose-built file server

The Synology RS2423+ is a 12-bay rackmount NAS delivered fully assembled with 48TB of enterprise drives and 1.6TB of cache. It targets small and medium businesses that need a ready-to-run platform for centralised file sharing, backup and virtualisation workloads. The AMD Ryzen processor and 32GB of memory provide the compute headroom for concurrent multi-user access.

Fit and alternatives

This unit suits organisations that want a pre-configured, tested appliance with high IOPS and sequential throughput for mixed read-write workloads. Buyers who need redundant power supplies, more than two 1GbE ports, or a different drive count should evaluate other models. Environments that require GPU acceleration or fibre-channel connectivity will not be served by this configuration.

Deciding specification

The installed 32GB of RAM is the key figure that determines whether the system can handle your planned virtual machines, Docker containers or heavy metadata operations. Confirm the memory capacity matches the sizing guide for your intended applications before purchase.

Questions about this item

What comes in the box and what must I buy separately?

The box contains the main unit, an accessory pack, an AC power cord and a quick installation guide. The twelve 4 TB enterprise drives, the M2D20 cache adapter and the two 800 GB cache modules are already installed. No additional drives or cache parts are required.

Which memory and cache configuration does this model include?

This unit ships with 32 GB of Synology RAM and 1.6 TB of cache built from two 800 GB Synology cache modules on the included M2D20 adapter. There are no other capacity options for this pre-configured SKU.

What do the 155 K IOPS and 3 500 MB/s figures mean for everyday file sharing?

Those numbers represent peak random read IOPS and sequential read throughput measured under ideal conditions. Real-world SMB file transfers will be lower and depend on network layout, client hardware and RAID overhead.
