Suited For And Not Suited For

This system suits organisations that require a turnkey, high-density storage platform with integrated 10GbE and 25GbE connectivity for virtualization, multi-site collaboration or surveillance workloads. Buyers who need more drive bays than twelve, a different processor architecture, or a tower form factor should evaluate alternative solutions.

Deciding Specification

The defining specification is the pre-configured 240TB of raw storage across twelve Synology enterprise drives paired with a dual-port 25GbE SFP28 adapter, providing immediate high-throughput capacity without additional drive procurement or network card installation.

Questions about this item

How do I verify the RS3626xs is delivering the published sequential speeds after setup?

Run a local benchmark against the 240 TB volume and compare results to the 6,300 MB/s read and 3,700 MB/s write figures Synology reports for this model.

Which drives and accessories ship with the RS3626xs and what must I source myself?

The box includes the 2U chassis, twelve pre-installed 20 TB Synology Enterprise drives, a Synology 2-port 25GbE SFP28 adapter, 16 GB DDR4 ECC RAM, two C13-to-C14 power cords, front cover and accessory pack; SFP28 transceivers and additional expansion cards are not included.

Should I choose the base 16 GB memory or upgrade toward the 48 GB maximum for virtualization workloads?

The installed 16 GB DDR4 ECC is sufficient for file services and backup; workloads running multiple VMs or containers benefit from adding modules up to the 48 GB supported limit.
