Ready-to-deploy 12-bay rackmount NAS

The Synology RS2423+ arrives fully assembled with twelve 4TB Synology Plus Series drives providing 48TB of raw capacity and 32GB of installed memory. An AMD Ryzen processor delivers up to 155K random read IOPS and 3,500 MB/s sequential read throughput. It targets small and medium businesses that need a cost-effective file management and sharing platform with advanced backup capabilities.

Network limits of 1GbE and single 10GbE

Two 1GbE RJ-45 ports support link aggregation and failover while a single 10GbE RJ-45 port provides higher throughput for demanding workloads. Sequential write throughput reaches 1,700 MB/s and random write IOPS reach 79K, so the 10GbE link can become the bottleneck before the storage subsystem does. No additional network interfaces are present on the base unit.

Slide-in trays simplify drive replacement

Twelve hot-swappable drive bays allow individual drives to be swapped without tools or system downtime. The unit weighs 11.5 kg without drives, so rack mounting requires adequate support rails and two people for safe installation. Operating temperature must stay between 0°C and 35°C with humidity from 5 to 95% RH to avoid thermal throttling or condensation issues.

Questions about this item

Should I pick the 12-bay version with 48 TB or a smaller bay count?

The 12-bay chassis holds twelve 4 TB Plus Series drives for 48 TB raw capacity, giving the most drive slots and highest raw space in this model line.

What does 3500 MB/s sequential read mean for daily file work?

Large files such as video projects or backups can stream at up to 3500 MB/s, so multi-user editing and bulk transfers finish quickly.

How does the single 10GbE port limit real-world speed?

The one 10GbE RJ-45 port caps network throughput at ten gigabit, so the 3500 MB/s internal rate is only reached over that link or via link aggregation on the two 1GbE ports.
