12-Bay Rackmount NAS for SMBs

The Synology RS2423+ is a 12-bay rackmount network-attached storage server designed for small and medium businesses. It arrives fully assembled and tested with twelve 12TB Synology Plus Series drives providing 144TB of raw capacity. An AMD Ryzen processor and 8GB of installed memory drive file management and sharing workloads. The system includes a 1.6TB Synology cache via an M2D20 adapter with two 800GB modules.

Network limits with 1GbE and 10GbE

The unit provides two 1GbE RJ-45 ports supporting Link Aggregation and Failover, plus a single 10GbE RJ-45 port. Sequential throughput reaches up to 3,500 MB/s read and 1,700 MB/s write, while random performance hits 155K read and 79K write IOPS. The 10GbE link caps peak transfer rates for clients without faster interfaces. Two USB 3.2 Gen 1 ports allow direct peripheral attachment but do not serve as primary storage uplinks.

Rackmount build with front drive access

The 2U chassis measures 88 mm high, 482 mm wide and 552 mm deep, weighing 11.5 kg without disks. Twelve front-loading drive bays enable hot-swap replacement without removing the unit from the rack. Rear-mounted power supplies connect via an included AC cord for 100-240 VAC operation. The system operates between 0°C and 35°C at 5-95% relative humidity, suitable for standard server rooms.

Questions about this item

How do I decide between the 12-bay 144 TB configuration and a smaller RS2423+ setup?

This unit arrives with twelve 12 TB Plus Series drives already installed, giving 144 TB raw capacity in a single 2U chassis. If your workload fits in less space you would need a different drive count, which is not offered in this pre-built bundle.

What does the 3,500 MB/s sequential read figure mean once the NAS is in production?

The manufacturer rates the RS2423+ at up to 3,500 MB/s sequential read and 1,700 MB/s sequential write with the included 1.6 TB cache. Real-world throughput will depend on RAID level, network link speed and client workload.

What does the single 10GbE RJ-45 port cap in practice?

The 10GbE port limits network transfers to 10 Gbps maximum. The two 1GbE ports can be aggregated for 2 Gbps or used for failover, but they cannot exceed 1 Gbps each.
