Overview

The RackStation RS826+ occupies a specific slot in Synology's lineup: a four-bay unit in a 1U rackmount chassis, aimed at offices that need shared storage living in the rack rather than under a desk. Synology quotes over 2,000 MB/s sequential read and 1,300 MB/s sequential write, framing the unit around office-wide file sharing, syncing, and backup running side by side. It arrives diskless. That means capacity planning, drive selection, and RAID configuration are all in the buyer's hands from day one.

Connectivity is where the RS826+ shows its intent. Four 1GbE RJ-45 ports are built in, which covers baseline networking and aggregation for a modest office without touching expansion. Above that sits a PCIe 3.0 slot, and it is genuinely flexible: it accepts an optional 10GbE or 25GbE network card, or an M.2 NVMe SSD adapter instead. Buyers chasing the quoted throughput figures will want the faster NIC, since four gigabit links will not get there. Growth is handled by a single Synology RX426 expansion unit, which takes the array from four bays to eight. Automated storage tiering works quietly underneath, relocating infrequently accessed data to lower-cost cold tiers and preserving the high-performance storage for active workloads. Synology covers the unit with a three-year warranty.

Frequently Asked Questions

It ships diskless. All four bays are empty, so drives are a separate purchase and you choose the capacity and RAID layout yourself.
Not over the four 1GbE RJ-45 ports alone. Reaching that figure requires installing an optional 10GbE or 25GbE NIC in the PCIe 3.0 slot.
Eight total. Connecting a single Synology RX426 expansion unit doubles the four built-in bays to eight.
Either an optional 10GbE or 25GbE network card, or an M.2 NVMe SSD adapter card. There is one slot, so it is one or the other.
It moves infrequently accessed data to lower-cost cold tiers automatically, keeping the high-performance storage available for active workloads.
One rack unit. The 1U chassis holds all four bays, so it stacks neatly with switches and other network gear.
Three years. That covers the RackStation chassis itself; drives you install carry their own manufacturer warranties.
