12-bay rackmount NAS holds 144 TB across twelve 12 TB drives, adds 800 GB cache via M2D20 adapter, and runs on AMD Ryzen with 16 GB RAM
The Synology RS2423+ arrives fully assembled with 16GB RAM, twelve 12TB enterprise drives providing 144TB of raw storage, and an 800GB cache pool on a dual 400GB M.2 adapter. A single 10GbE port and dual 1GbE links with aggregation support handle heavy file traffic. Two USB 3.2 Gen 1 ports add direct backup or expansion options.
This configuration fits small-to-medium businesses that need immediate, high-capacity shared storage with built-in flash acceleration for metadata and hot data. Organisations requiring redundant power supplies, more than one 10GbE link, or GPU-accelerated workloads should evaluate other platforms.
The twelve 12TB drives determine the usable capacity and redundancy level you can configure in DSM. If your dataset will exceed this raw figure or you need a different drive class, the chassis cannot accommodate additional internal bays.
Measured against everything we stock in Rack-Mounted NAS Servers, at today’s prices. Recalculated every night.

That figure represents peak small-block performance; actual file access speed depends on network throughput, RAID layout and the mix of read and write operations in your workload.
The 10GbE port limits maximum network throughput to ten gigabits per second; sustained speeds will be lower due to protocol overhead, disk performance and client configuration.
The chassis is 88 mm tall, matching a standard 2U rack space, and extends 552 mm deep from the mounting ears.
