Short Description

The Synology RS826RP+ is a 4-bay 1U rackmount NAS designed for businesses that need compact, expandable storage with redundant power for improved service continuity.

It combines Ryzen processing, ECC memory, four Gigabit ports, PCIe expansion and support for up to eight drives with the added resilience of redundant power.

Why Choose This Synology

Added Protection with Redundant Power

The RS826RP+ provides redundant power supplies, helping maintain system availability if a single PSU or power connection fails.

Four Network Ports Built In

Four 1GbE network interfaces provide flexible connectivity, failover and Link Aggregation options.

Upgrade to Faster Networking

Compatible Synology PCIe cards allow the system to be upgraded to 10GbE or 25GbE as network requirements increase.

Add High-Speed SSD Cache

M2D20 and E10M20-T1 adapter cards provide support for compatible M.2 NVMe SSD cache without consuming the four front storage bays.

Scale to Eight Drives

One RX426 expansion unit doubles total drive support from four to eight bays.

Best For

• Branch offices
• Remote locations
• Small and medium businesses
• Business-critical shared storage
• Backup and recovery
• Multi-site file synchronisation
• Surveillance
• Businesses requiring redundant power
• Future 10GbE or 25GbE deployments

Product Description

The Synology RackStation RS826RP+ combines compact 1U storage with additional power-supply redundancy for environments where service continuity matters.

It is powered by the AMD Ryzen V1500B processor with 4 cores and 8 threads running at 2.2GHz.

The system includes 4GB DDR4 ECC memory and supports expansion to a maximum of 32GB.

Four hot-swappable SATA bays support compatible 3.5-inch HDDs and 2.5-inch SATA SSDs. A compatible RX426 expansion unit can increase total storage to eight drive bays.

Four built-in 1GbE RJ-45 ports provide network redundancy and Link Aggregation options. A PCIe Gen3 x8 slot with an x4 link supports compatible Synology 10GbE, 25GbE and SSD-cache adapter cards.

The RS826RP+'s key difference from the RS826+ is its redundant power design, providing additional protection against a single power-supply failure.

Synology DSM provides integrated file storage, backup, synchronisation, collaboration, surveillance and data-protection tools.

Storage drives are sold separately.
