Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralised file storage with integrated 10GbE connectivity. It ships fully assembled with twelve 4 TB enterprise SATA drives, 800 GB of enterprise cache and 32 GB of DDR4 ECC memory. A 6-core Intel Xeon D-1726 processor drives virtualization, backup and surveillance workloads.

Suits growing teams needing expansion room

This unit fits organisations that want redundant power supplies, dual 10GbE RJ-45 ports and two PCIe Gen 4 x8 slots for future network or cache upgrades. Buyers who require a compact desktop chassis, single power supply or fewer than twelve drive bays should consider smaller form factors. The 14.5 kg weight and 724 mm depth also demand a standard rack with adequate rail support.

Twelve-bay capacity defines the deployment

With twelve 3.5-inch SATA bays populated by 4 TB drives, the system delivers 48 TB of raw storage in a single 2U appliance. This bay count determines how many drives you can add or replace without purchasing an expansion unit. If your dataset will outgrow twelve bays, plan for a larger chassis or external expansion from the start.

Questions about this item

What comes in the box and what must I buy separately?

The shipment includes the main unit, an accessory pack, two C13 to C14 power cords and a front cover. All twelve drive bays are already populated with 4 TB enterprise drives and the two cache modules are installed. No additional drives or cache hardware are required.

Should I choose a different memory or cache configuration for my workload?

This unit ships with 32 GB of DDR4 memory and 800 GB of enterprise cache built from two 400 GB modules. The memory can be expanded to 48 GB if your applications need more capacity, while the installed cache is ready for read-write acceleration out of the box.

What do the published 6,300 MB/s read and 3,700 MB/s write figures mean in practice?

Those sequential throughput numbers come from Synology's internal test environment using the integrated 10 GbE ports. Real-world speeds will depend on your network infrastructure, the RAID layout you select and the mix of random versus sequential I/O your applications generate.
