Overview

The Synology DS723+ pairs an AMD Ryzen R1600 dual-core processor with 2GB of DDR4 ECC memory in a compact 2-bay form factor, targeting small businesses and advanced home users who need reliable network-attached storage with room to grow. The Ryzen R1600 is a meaningful step up from the Celeron and ARM chips found in many competing 2-bay units — it provides enough headroom for running Docker containers, Synology's suite of productivity apps, and handling encrypted file transfers without bottlenecking. ECC memory is a notable inclusion at this price tier, offering single-bit error correction that protects data integrity during write operations and long-term storage — a feature typically reserved for higher-end units.

Where the DS723+ distinguishes itself is scalability. The two internal bays accept 3.5" or 2.5" SATA drives, and connecting a DX517 expansion unit extends total capacity to seven bays, supporting RAID 5 and RAID 6 configurations. Dual 1GbE LAN ports support Link Aggregation for improved multi-client throughput, though power users handling large media files will likely want to add a 10GbE adapter through the available expansion slot. The single USB 3.2 Gen 1 port handles external backup drives or UPS connections. Synology's DSM operating system remains the unit's strongest differentiator — it provides snapshot-level backup, cloud sync, surveillance station support, and a mature package ecosystem that turns this compact NAS into a genuinely versatile server appliance. For workloads that don't demand hardware transcoding or high single-client bandwidth out of the box, the DS723+ offers a well-engineered foundation that can scale with your needs.

Pros & Cons

👍 Pros

  • AMD Ryzen R1600 dual-core processor delivers measurably stronger multi-threaded performance than ARM or Celeron-based NAS units in this class.
  • DDR4 ECC memory detects and corrects single-bit errors, providing data integrity assurance critical for long-term file storage.
  • Scalable from 2 to 7 bays via DX517 expansion, extending usable life as storage demands grow without full hardware replacement.
  • Synology DSM operating system provides a mature, regularly updated software ecosystem including snapshot replication, Hyper Backup, and Docker support.
  • Compact physical footprint fits desktop or shelf deployment without dedicated rack infrastructure.

👎 Cons

  • Dual 1GbE ports cap single-client transfer speeds at approximately 125 MB/s — insufficient for large video editing workflows without a 10GbE upgrade.
  • Base 2GB RAM requires an upgrade for Docker-heavy or multi-application workloads, adding to the total cost of ownership.
  • No HDMI output limits direct-attached media playback use cases that some competing NAS units support.
  • Lack of integrated hardware transcoding engine makes the DS723+ a weaker choice for Plex or media server duties compared to Intel Quick Sync alternatives.
  • Single USB 3.2 Gen 1 port restricts simultaneous external device connectivity for backup or UPS management.

Frequently Asked Questions

Yes. Connecting a Synology DX517 expansion unit scales the DS723+ from 2 bays to a maximum of 7 bays, providing significant raw storage growth without migrating to a larger NAS chassis.
The 2GB base configuration is adequate for core file serving and backup tasks, but memory-intensive workloads like running multiple Docker containers, Synology Surveillance Station with many cameras, or large-scale virtual machines will benefit from upgrading to the maximum 32GB supported.
Each port provides up to 125 MB/s theoretical throughput. Using Link Aggregation (LAG), you can achieve up to 250 MB/s aggregate bandwidth across multiple simultaneous connections — though a single client session is still capped at 1GbE speeds. For faster single-client transfers, a 10GbE adapter via the expansion slot is available.
The Ryzen R1600 dual-core processor handles basic transcoding workloads, but it lacks a dedicated hardware transcoding engine. For 4K transcoding or multiple simultaneous streams, expect performance limitations compared to Intel-based Synology units with Quick Sync.
With two drives, you can configure SHR (Synology Hybrid RAID), RAID 1 for mirroring, RAID 0 for maximum capacity, or JBOD. SHR and RAID 1 provide single-drive redundancy. Expanding via the DX517 unlocks RAID 5 and RAID 6 options.
