Synology RS826RP+ 4-Bay Rackmount NAS
The Synology RS826RP+ is a compact 1U rackmount NAS built for edge deployments, branch offices, and remote business workloads. It ships fully assembled and tested with a quad-core AMD Ryzen V1500B processor, 4GB DDR4 RAM, four 8TB Synology Plus drives, and 3.2TB of enterprise cache. Four 1GbE RJ-45 ports support Link Aggregation for bandwidth and failover. A PCIe Gen3 slot allows 10GbE, 25GbE, or M.2 SSD adapters for future growth.
Thermals Noise Power Normal Use
The unit operates within a 0°C to 35°C temperature range and 5% to 95% relative humidity. Dual redundant power supplies accept 100-240 VAC at 50/60Hz for continuous availability. The 44 mm × 480 mm × 492.6 mm chassis weighs 8.0 kg and fits standard 19-inch racks. Hot-swappable bays support 3.5-inch SATA HDDs and 2.5-inch SATA SSDs without downtime during drive replacement.
Sustained Load Behaviour Expansion
Under Synology tested configuration the system delivers sequential read performance over 2,000 MB/s and write performance over 1,300 MB/s. Connecting one RX426 expansion unit increases capacity to eight drive bays and up to 192 TB raw storage using supported 24 TB drives. Compatible SSDs can be added for caching to reduce latency and improve IOPS in HDD-based arrays during heavy workloads.

Questions about this item
How do I install the Synology Enterprise Cache modules, and what step is commonly missed?
Insert the two 1.6 TB cache modules into the internal M.2 slots, then enable SSD cache in DSM Storage Manager; the step often missed is creating the cache volume after the hardware is recognised.
Which components will need replacement first under continuous operation?
The four 8 TB Synology Plus drives are the primary wear items; the 1.6 TB cache modules and the 4 GB DDR4 memory have no moving parts and typically outlast the mechanical drives.
What performance limit appears first during sustained heavy workloads?
The four 1 GbE ports cap aggregate throughput at roughly 1 000 MB/s, so network bandwidth saturates before the Ryzen V1500B processor or the 3.2 TB cache reach their limits.
