4-Bay Xeon Rackmount NAS
The Synology RS1626xs+ is a 1U enterprise rackmount NAS built around an Intel Xeon D-1726 six-core processor and 32 GB of DDR4 ECC memory. It ships fully assembled with four 8 TB Synology enterprise drives providing 32 TB of raw storage. The system targets businesses that need virtualization, file sharing, backup and surveillance in a compact rackmount form factor.
Dual 25GbE and 10GbE networking
Two built-in 10GbE RJ-45 ports and a Synology PCIe card with dual SFP28 25GbE ports handle high-throughput workloads. A dedicated out-of-band management LAN port keeps administration separate from data traffic. The unit operates between 5 °C and 35 °C on 100–240 VAC power with redundant C13 to C14 cords.
32 TB pre-populated with enterprise drives
The array arrives with four 8 TB Synology Enterprise NAS drives installed and tested, delivering 32 TB of capacity immediately. Two M.2 NVMe slots and a PCIe Gen4 x8 slot allow cache or expansion, while a compatible Synology expansion unit can scale the system to 16 drives. Buyers who need more bays or a different drive configuration should consider other models.

Questions about this item
How do I install the 2-Port 25GbE PCIe card and which slot should I use?
Insert the Synology 2-Port 25GbE Adapter into the PCIe Gen4 x8 expansion slot; the unit arrives fully assembled and tested with the card already seated in that slot.
Which components may need replacement after extended operation?
The four 8TB Synology Enterprise NAS drives are the primary field-replaceable units; the 16GB DDR4 ECC RDIMM memory and M.2 NVMe cache modules can also be swapped if required.
What thermal limit appears first during sustained heavy workloads?
The operating temperature ceiling of 35 °C is the first environmental limit reached under continuous high load; internal throttling protects the Xeon D-1726 processor before that point.
