Private cloud for home and small office

The Synology DS223 is a two-bay desktop NAS that arrives without drives and supports up to 36 TB of raw capacity. It runs a quad-core Realtek RTD1619B processor at 1.7 GHz with 2 GB of DDR4 memory. One 1 GbE port and three USB 3.2 Gen 1 ports handle network and external storage connections. The unit targets households and small teams that want a personal cloud for backup, file sharing and media streaming.

Upgrade from single-drive or USB storage

Moving from a single external drive or basic USB enclosure to the DS223 adds RAID redundancy, centralized access protocols such as SMB, NFS and iSCSI, and on-demand sync with public cloud services. The jump is worth it when data protection, multi-device access and scheduled backups become daily requirements rather than occasional tasks. The 14 % faster import rate noted by the manufacturer helps migrate existing libraries more quickly.

Sustained operation at low power

Under continuous access the system draws 17.343 W, dropping to 4.08 W when the installed drives enter hibernation. The fanless design keeps acoustic output minimal during long backup windows or overnight media indexing. Operating temperature range spans 0 °C to 40 °C, so the chassis remains stable in typical office or closet environments without active cooling.

Questions about this item

Which drive sizes fit the DS223's two SATA bays?

The unit accepts two 3.5-inch or 2.5-inch SATA hard drives or SSDs, giving a maximum raw capacity of 36 TB.

How do I install drives in the DS223, and what step is often missed?

Slide each drive into a bay until it clicks, then secure it with the provided screws; the step people skip is tightening those screws, which prevents vibration and connection issues.

What ongoing maintenance does the DS223 require?

Keep the operating temperature between 0 °C and 40 °C, clean dust from the ventilation openings periodically, and replace any drive that SMART reports as failing.
