Synology RS3626xs 12-Bay Rackmount NAS
The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need high-capacity, centralised file storage and data protection. It ships fully assembled and tested with twelve 16 TB enterprise drives for a total of 192 TB raw capacity. A 6-core Intel Xeon D-1726 processor and 32 GB of DDR4 ECC memory handle virtualization, surveillance and multi-site collaboration workloads. Redundant power supplies protect service availability from a single power-supply failure.
Network bandwidth limits with dual 10GbE
Two integrated 10GbE RJ-45 ports support Link Aggregation for increased throughput, load balancing and network failover. Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions. Actual throughput depends on client network infrastructure, drive configuration and workload mix; the dual 10GbE interfaces set the practical ceiling for single-appliance bandwidth. Two PCIe Gen 4 x8 slots allow future addition of compatible 25GbE or Fibre Channel adapters if higher speeds become necessary.
192 TB raw capacity from twelve enterprise drives
The installed drive set consists of twelve 3.5-inch 16 TB Synology Enterprise NAS drives, delivering 192 TB of raw storage in a single 12-bay chassis. This capacity determines how much data the appliance can hold before expansion units are required. Buyers who need more raw capacity than 192 TB must plan for external expansion or a larger chassis. The system supports both 3.5-inch SATA HDDs and 2.5-inch SATA SSDs for future drive replacements or tiering.

Questions about this item
Should I choose the 12-bay 192TB configuration or look for a different capacity?
This unit ships as a fully assembled 12-bay system with twelve 16TB Synology Enterprise NAS drives, providing 192TB of raw capacity out of the box.
What do the quoted 6,300 MB/s read and 3,700 MB/s write figures mean for everyday workloads?
Those are Synology's reported sequential throughput numbers under their test conditions; actual speeds will vary with RAID type, file sizes, network topology and concurrent workloads.
How do the two integrated 10GbE RJ-45 ports and the PCIe Gen 4 x8 slots limit expansion?
The two onboard 10GbE ports support Link Aggregation for bandwidth and failover, while two PCIe Gen 4 x8 slots allow adding compatible 10GbE, 25GbE, Fibre Channel or SSD caching adapters.
