Enterprise 12-Bay Rackmount NAS
The Synology RS3626xs is a 2U rackmount network-attached storage server built for organizations that need high-capacity, centralized data management. It arrives fully assembled with twelve drive bays populated by 24TB enterprise hard drives, delivering 288TB of raw storage out of the box. The system targets IT departments handling virtualization, surveillance, and multi-site file collaboration workloads. It is not suited for buyers who need a desktop form factor or a lower-capacity starter appliance.
48GB DDR4 ECC Memory
The unit ships with 48GB of DDR4 ECC memory installed, reaching the maximum supported capacity for the Xeon D-1726 processor. This memory ceiling determines how many virtual machines, containers, or concurrent user sessions the NAS can sustain without paging to disk. Buyers planning heavier consolidation or larger deduplication volumes cannot expand beyond this limit and would need a different platform.
Pre-Populated Drive Installation
Because all twelve 3.5-inch SATA drives are factory-installed and the system is pre-tested, physical deployment is limited to rack mounting, connecting the two C14 power cords, and linking the two 10GbE RJ-45 ports or the 25GbE SFP28 adapters. The main installation risk is verifying that the rack depth accommodates the 724mm chassis and that the site power falls within the 100-240 VAC range; the unit weighs 14.5 kg and requires two-person handling or a lift.

Questions about this item
What does the 288 TB of installed enterprise drives mean for usable capacity in a typical RAID setup?
Twelve 24 TB drives give 288 TB raw; with Synology Hybrid RAID or RAID 6 you lose two drives for parity, leaving roughly 240 TB usable before filesystem overhead.
What real-world throughput can the two 25 GbE SFP28 ports sustain?
Synology reports sequential reads above 6 300 MB/s and writes above 3 700 MB/s under its test conditions; actual speeds depend on network switches, cabling and workload mix.
How much rack depth does the 724 mm chassis need including cables?
The unit is 724 mm deep; allow extra space at the rear for power cords and SFP28 cables so the total clearance exceeds the chassis length.
