Rackmount NAS for Enterprise Workloads

The Synology RS3626xs is a 2U, 12-bay rackmount NAS built for demanding business environments. It arrives fully assembled with an Intel Xeon D-1726 processor, 8 GB of DDR4 ECC memory, a dual-port 10GbE adapter, and twelve 4 TB enterprise drives providing 48 TB of raw capacity. Redundant power supplies protect service availability from single power-supply failure. The system supports expansion to 48 GB of memory and offers two PCIe Gen 4 x8 slots for additional connectivity.

Suits Centralised Storage and Virtualization

This unit fits organisations that need high-capacity, centralised file storage, data protection, virtualization hosting, or multi-site collaboration with 10 GbE performance. Buyers who require 25 GbE or Fibre Channel connectivity out of the box, or who need more than twelve drive bays without adding expansion units, should consider other platforms. The pre-installed 4 TB drives set the baseline capacity; different drive sizes are not included in this configuration.

12-Bay Chassis Defines Maximum Internal Drives

The twelve 3.5-inch SATA bays set the hard limit for internal hard drives or SSDs. With twelve 4 TB drives installed, the raw capacity is 48 TB before any RAID overhead. Adding more internal storage requires an external expansion chassis connected via the PCIe slots. The 100-240 VAC redundant power supplies and 0 °C to 35 °C operating range support standard rack deployments.

Questions about this item

What drives and accessories are already inside the RS3626xs when it arrives?

The unit ships fully assembled with twelve 4TB Synology Enterprise NAS drives installed, 8GB of DDR4 ECC memory, and a Synology 2-port 10GbE adapter. The box also includes two C13-to-C14 power cords, a front cover and an accessory pack.

Should I choose the 48TB configuration or add larger drives later for more capacity?

This model comes with 48TB (12 x 4TB) of enterprise drives pre-installed. All twelve 3.5-inch bays are occupied, so any capacity increase would require replacing existing drives with higher-capacity SATA HDDs or SSDs.

What do the quoted 6,300 MB/s read and 3,700 MB/s write speeds mean for daily workloads?

Those are Synology's sequential throughput figures under test conditions using the integrated 10GbE ports. Real-world performance will vary with RAID level, file size, network topology and the mix of concurrent applications such as virtualization or backup.
