Ready-to-deploy 1U rackmount NAS

The Synology RS826+ arrives fully assembled with four 16 TB Synology Plus drives, a 2-port 25GbE SFP28 adapter and 32 GB of DDR4 ECC memory. A Ryzen V1500B four-core processor powers the unit, making it suitable for edge sites and remote offices that need immediate storage capacity without on-site build time.

Passive-cooled 1U chassis in standard racks

The 44 mm high enclosure operates between 0 °C and 35 °C at up to 95 % relative humidity on 100–240 VAC power. Four 1 GbE RJ-45 ports and the installed 25GbE adapter handle network traffic while the compact form factor keeps rack density high and acoustic output low for shared infrastructure rooms.

Four-bay SATA foundation with PCIe headroom

Four drive bays accept 3.5-inch or 2.5-inch SATA media, leaving the single PCIe Gen3 slot open for future network upgrades. Two USB 3.2 Gen 1 ports provide direct-attached backup or peripheral connections, and web-based management with DHCP simplifies deployment across distributed locations.

Questions about this item

How do I install the Synology 2-Port 25GbE Adapter into the RS826+ PCIe slot, and what step is commonly missed?

Power down the unit, remove the chassis cover, insert the adapter into the PCIe Gen3 slot until it clicks, secure the bracket screw, replace the cover, then enable the ports in DSM Control Panel — the step most often missed is forgetting to configure Link Aggregation or VLAN tagging after the hardware is recognised.

Which components in this RS826+ will need replacement first under continuous operation?

The four 16TB Synology Plus SATA drives are the primary wear items; plan to replace them after their rated workload or when SMART alerts appear, while the 32GB DDR4 ECC memory and AMD Ryzen V1500B processor typically last the chassis lifetime.

What thermal limit appears first when the RS826+ runs sustained workloads in a 35 °C rack?

The 0°C–35°C operating ceiling is the first boundary; prolonged loads at the top of this range trigger fan-speed ramps and possible CPU throttling before any drive or memory limit is reached.
