12-Bay Rackmount NAS for SMBs

The Synology RS2423+ is a 12-bay rackmount NAS delivered fully assembled and tested with 48 terabytes of Synology Plus Series drives and 16 gigabytes of installed memory. An AMD Ryzen processor powers the unit, while a dedicated M2D20 cache adapter adds 800 gigabytes of Synology cache for accelerated workloads. Two 1GbE ports with link aggregation and failover plus one 10GbE port provide flexible network connectivity for file management and sharing.

Upgrade from smaller or slower storage

Teams running out of bays on a 4-bay or 8-bay system gain twelve drive slots and a 10GbE uplink in a single 2U chassis. The jump is worth it when random I/O becomes a bottleneck, as the platform sustains over 155K random read IOPS and 79K random write IOPS. Two USB 3.2 Gen 1 ports allow direct attachment of external backup targets without consuming network bandwidth.

Sustained throughput under load

Sequential performance reaches up to 3,500 megabytes per second read and 1,700 megabytes per second write, enabling large-file workflows to run continuously without thermal throttling. The rackmount form factor operates reliably between 0 and 35 degrees Celsius at 5 to 95 percent relative humidity. Buyers who need redundant power supplies or more than twelve bays in one appliance should evaluate higher-tier models.

Questions about this item

What rack depth and height does the RS2423+ require?

The unit measures 88 mm high and 552 mm deep, fitting a standard 2U rack space with at least 552 mm usable depth.

Which step is often missed when installing the M2D20 cache adapter?

Insert the two 400 GB cache modules into the M2D20 adapter, secure them with the supplied screws, then seat the adapter in the internal PCIe slot before powering on.

When should the twelve 4 TB Plus Series drives be considered for replacement?

Plan replacement after the rated workload limit or when SMART health indicators show reallocated sectors, typically after several years of continuous operation.
