Compact 1U rackmount NAS for edge and branch offices

The Synology RS826RP+ is a 1U rackmount network-attached storage system built around a quad-core AMD Ryzen V1500B processor running at 2.2 GHz with 8GB of DDR4 memory. It ships fully assembled and tested with four 20TB Synology Plus drives for 80TB of raw capacity and two 1.6TB enterprise SSDs providing 3.2TB of cache. Four integrated 1GbE RJ-45 ports support Link Aggregation for bandwidth scaling and failover, targeting remote business workloads and edge deployments.

Verify rack space and drive compatibility before

The unit measures 44 mm high, 480 mm wide and 492.6 mm deep and weighs 8.0 kg, so confirm your rack can accommodate a 1U form factor with adequate airflow within the 0°C to 35°C operating range. The four hot-swappable bays accept 3.5-inch SATA hard drives and 2.5-inch SATA SSDs only; other drive interfaces are not supported. A single Synology RX426 expansion unit can be attached later to double the bay count to eight and raise raw capacity to 192TB using supported 24TB drives.

Bundled cache SSDs and expansion slot shape

The pre-installed 3.2TB (2 x 1.6TB) Synology Enterprise Cache SSDs accelerate read and write IOPS for HDD-based arrays, reducing latency for frequently accessed data. A PCIe Gen3 slot allows adding a 10GbE or 25GbE network adapter, an M.2 SSD adapter, or a combined M.2 and 10GbE card, but compatible adapters are sold separately. Two USB 3.2 Gen 1 ports provide external connectivity for backup targets or peripheral devices.

Questions about this item

What drives and cache come pre-installed in the RS826RP+ and what must I add?

The unit ships fully assembled with four 20 TB Synology Plus NAS drives and two 1.6 TB Synology Enterprise Cache SSDs. All four bays are populated, so no additional drives are required unless you attach an RX426 expansion unit.

Should I choose the RS826RP+ with 8 GB memory or look for a larger capacity?

This configuration includes 8 GB of Synology DDR4 RAM and 80 TB of raw storage from the four 20 TB drives. Memory is not user-expandable on this model, so select this version if the installed capacity meets your workload.

What does the quoted 2,000 MB/s sequential read mean for daily file access?

The 2,000 MB/s sequential read and 1,300 MB/s sequential write are measured under Synology's test configuration using the AMD Ryzen V1500B at 2.2 GHz. Real-world speeds will vary with network topology, drive health, and workload mix.
