4-Bay Rackmount NAS for Enterprise Workloads
The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for businesses that require high-throughput file sharing, virtualization hosting and backup consolidation. An Intel Xeon D-1726 six-core processor and 16GB of DDR4 ECC memory provide the compute headroom for simultaneous VMs and heavy multi-user access.
Dual 10GbE and NVMe Cache Acceleration
Two integrated 10GbE RJ-45 ports remove the typical gigabit bottleneck for database and media workloads, while a dedicated 1GbE management lane keeps administration traffic separate. The factory-installed 1.6TB NVMe cache tier (2 × 800GB) absorbs random read/write bursts, lowering latency for virtual disks and frequently accessed datasets.
32TB Raw Capacity with Expansion Headroom
Four pre-installed 8TB enterprise drives deliver 32TB of raw storage in a single volume or RAID array, suitable for department-scale file repositories and surveillance archives. The chassis supports an additional Synology expansion unit to grow to 16 bays, while the PCIe Gen4 x8 slot remains open for further networking or HBA upgrades.

Questions about this item
What drive replacements will the four 8 TB bays accept later?
The four bays hold 8 TB Synology Enterprise drives; replacements must match the 3.5-inch form factor and the NAS drive firmware expectations.
Which component hits its ceiling first during non-stop 10 GbE transfers?
The dual 10 GbE RJ-45 ports saturate at 10 Gbps before the Xeon D-1726 or the 1.6 TB NVMe cache become bottlenecks.
How loud and hot does the 1U chassis get when it runs 24/7 at 35 °C ambient?
The 1U rackmount design relies on internal fans that ramp up under load; at the 35 °C operating limit the unit stays within spec but audible fan noise increases noticeably.
