Ready-to-Run 12-Bay Rackmount NAS

The Synology RS2423+ arrives fully assembled with 12 enterprise-class 4TB drives delivering 48TB of raw capacity and 16GB of installed memory. It is built for small and medium businesses that need immediate file management, sharing and backup without the delay of drive installation or initial configuration.

Enterprise Drives Plus Dedicated Cache

Twelve Synology Enterprise drives provide the storage foundation while the included M2D20 adapter adds 800GB of Synology cache across two 400GB modules. This combination accelerates random read and write IOPS to 155K and 79K respectively and sustains sequential throughput up to 3500 MB/s read and 1700 MB/s write for demanding workloads.

Verify Rack Space and Network Uplink

Confirm your rack can accommodate a unit measuring 88 mm high by 482 mm wide by 552 mm deep and that the 11.5 kg diskless weight is within your shelf rating. Ensure you have a 10GbE switch port for the single 10GbE RJ-45 uplink and that the two 1GbE ports can be aggregated or used for failover as required.

Questions about this item

How often will the 400 GB Synology cache modules need replacement?

The 800 GB cache uses two 400 GB Synology modules installed in the M2D20 adapter; they are solid-state with no moving parts and typically last the life of the NAS under normal workloads.

What throughput ceiling appears first during sustained transfers?

Sequential throughput reaches up to 3,500 MB/s read and 1,700 MB/s write, so the 10 GbE port is the first bottleneck for continuous large-file traffic.

How loud and hot does the RS2423+ get when running 24/7?

Operating temperature range is 0 °C to 35 °C; the 12 drive bays and dual power supplies generate noticeable airflow noise, so rack mounting in a cooled room is recommended.
