help Synology DiskStation DS1821+ FAQ
How many drive bays does the Synology DS1821+ have?
The DS1821+ has 8 front-accessible drive bays. It is aimed at users who need more storage headroom than a 2-bay or 4-bay NAS can provide.
Can the DS1821+ be expanded beyond 8 drives?
Yes. The DS1821+ supports Synology DX517 expansion units, which can add more bays for larger storage pools or volumes depending on the configuration.
What processor is in the Synology DS1821+?
The DS1821+ uses an AMD Ryzen embedded processor rather than the Intel Celeron chips found in many smaller Synology models. That helps with heavier file-serving and business NAS workloads.
Does the DS1821+ include 10GbE networking?
The DS1821+ does not ship with built-in 10GbE ports, but it has a PCIe expansion slot for an optional network card. Out of the box, it includes multiple 1GbE LAN ports.
