Synology DS723+
Quick Answer+


Quick Answer: The Synology DS723+ (~$450) is Synology's most powerful 2-bay NAS. Unlike the DS224+ (Intel/multimedia focus), the DS723+ features an AMD Ryzen R1600 CPU, 10GbE upgrade capability, NVMe cache slots, and expandability to 7 drives. Best for: power users who want maximum features in a compact form, Docker/VM workloads, and those planning to expand later. Skip if: Plex transcoding is your priority (get DS224+ instead).

The Synology DS723+ breaks the mold of what a 2-bay NAS can do. While most 2-bay units are entry-level devices, the DS723+ packs the same AMD Ryzen power, 10GbE capability, and expansion options found in larger models like the DS923+.

This review covers everything: specifications, real-world performance, comparison with the DS224+, and who should choose this compact powerhouse.

What Makes the DS723+ Special

AMD Ryzen Power in 2-Bay Form Factor

The DS723+ is the only 2-bay Synology with the AMD Ryzen R1600 processor. This gives it capabilities typically reserved for 4+ bay units:

  • Faster processing: 2.6 GHz base, 3.1 GHz turbo
  • ECC memory support: Up to 32GB for data integrity
  • Better Docker/VM performance: More headroom than Celeron-based 2-bays
  • Hardware encryption: AES-NI for fast encrypted transfers

10GbE Ready

Unlike any other 2-bay NAS in Synology's lineup, the DS723+ supports 10GbE networking via the E10G22-T1-Mini module. This enables:

  • Sustained transfers over 500 MB/s (vs ~115 MB/s on 1GbE)
  • Practical for video editors working with large files
  • Future-proofing as 10GbE becomes more common

NVMe Cache Slots

Two M.2 2280 NVMe slots on the bottom of the unit allow SSD caching to dramatically improve random I/O performance. This is invaluable for:

  • Synology Drive file syncing
  • Virtual machine storage
  • Docker container databases
  • Photo library browsing in Synology Photos

Note: Unlike the DS923+, the DS723+ only supports NVMe for caching, not storage pools.

Expandability to 7 Drives

The "7" in DS723+ refers to maximum expansion capability:

  • 2 internal bays
  • + 5 bays via DX517 expansion unit
  • = 7 total drives

This is unique among 2-bay NAS devices - you can start small and grow into a 7-drive array without replacing your NAS.

PCIe 3.0 x2 Slot

In addition to the 10GbE module slot, there's a PCIe slot for additional expansion cards. Options include M.2 adapters or additional network cards.

DS723+ vs DS224+: The Key Decision

Synology offers two premium 2-bay NAS options with very different strengths:

FeatureDS723+ (~$450)DS224+ (~$300)
CPUAMD Ryzen R1600Intel Celeron J4125
RAM2GB ECC (max 32GB)2GB (max 6GB)
10GbE Option✅ Yes❌ No
NVMe Slots✅ 2x M.2❌ None
PCIe Slot✅ PCIe 3.0 x2❌ None
Expansion✅ Up to 7 drives❌ 2 drives only
Plex TranscodingLimited (AMD GPU)Good (Intel QSV)
ECC Memory✅ Supported❌ No
Best ForPower users, expansionPlex, multimedia

Choose DS723+ If:

  • You want 10GbE networking capability
  • You plan to add expansion unit later
  • Running Docker containers or VMs
  • Need NVMe caching
  • Want more than 6GB RAM
  • Data integrity (ECC memory) matters

Choose DS224+ If:

  • Plex transcoding is your primary use case
  • Budget is a priority (~$150 savings)
  • You don't need expansion capability
  • 4K hardware transcoding is important
  • Simple backup/file sharing only

Ideal Use Cases

Starter NAS with Growth Potential

The DS723+ is perfect for users who want to start small but grow:

  • Begin with 2 drives in RAID 1 (mirrored)
  • Add DX517 expansion when more capacity needed
  • Migrate existing RAID to expanded array without data loss
  • No need to buy a new NAS when you outgrow 2 bays

Home Office / Remote Worker

Compact yet powerful enough for professional use:

  • Synology Drive: Self-hosted Dropbox alternative
  • Active Backup: Automatic PC/Mac backup
  • 10GbE: Fast access to large project files
  • Compact footprint: Desktop-friendly size

Docker & Home Lab

The Ryzen CPU and expandable RAM support serious containerized workloads:

  • Container Manager: Native Docker support
  • Home Assistant: Smart home automation
  • Pi-hole: Network-wide ad blocking
  • Nextcloud: Self-hosted cloud storage

Upgrade RAM to 8-16GB for multiple containers running simultaneously.

Video Editing Workstation Storage

With 10GbE connectivity:

  • Edit directly from NAS at 500+ MB/s
  • Store project archives centrally
  • NVMe cache improves responsiveness
  • Start with 2 drives, expand as library grows

For a 2-bay setup, consider larger capacity drives (8TB+) to maximize storage from limited bays. WD Red Plus or Seagate IronWolf are ideal choices.

See our complete Synology Compatible Drives Database for verified compatibility.

RAID Configuration for 2-Bay NAS

With only 2 bays, your RAID options are limited but straightforward:

ConfigurationRAID LevelUsable CapacityProtection
2× 8TBRAID 1 / SHR8TB1-drive fault tolerance
2× 12TBRAID 1 / SHR12TB1-drive fault tolerance
2× 16TBRAID 1 / SHR16TB1-drive fault tolerance
2× 8TBRAID 016TB❌ None (not recommended)

Recommendation: Always use RAID 1 or SHR with a 2-bay NAS. The 50% capacity loss is worth the data protection. Never use RAID 0 for important data.

Use our RAID Calculator to plan configurations including expansion.

Expansion Path Example

Here's how the DS723+ can grow with your needs:

StageConfigurationUsable Capacity
InitialDS723+ with 2× 8TB (SHR)8TB
Year 2Add DX517 with 3× 8TB32TB (5-drive SHR)
Year 3Add 2 more 8TB to DX51748TB (7-drive SHR)
LaterReplace drives with largerScale up capacity

This flexibility is unique to the DS723+ among 2-bay NAS units.

Plex on DS723+

The AMD Ryzen R1600 has limited transcoding capability:

  • Direct Play: Unlimited streams ✅
  • 1080p Transcoding: 1-2 streams
  • 4K Transcoding: Not practical

If Plex transcoding is your primary need, get the DS224+ instead. Its Intel Celeron J4125 with Quick Sync handles transcoding much better.

For direct play setups (Apple TV, Shield, modern smart TVs), the DS723+ works perfectly.

Frequently Asked Questions

DS723+ vs DS224+: Which should I buy?

Choose DS723+ for: 10GbE capability, expansion to 7 drives, NVMe caching, Docker/VMs, more than 6GB RAM. Choose DS224+ for: Plex transcoding (Intel Quick Sync), lower price (~$150 less), simple multimedia setup. The DS723+ is for power users; the DS224+ is for multimedia-focused users.

Does the DS723+ support 10GbE?

Yes. The DS723+ supports 10GbE via the E10G22-T1-Mini upgrade module (~$110). It's the only 2-bay Synology with this capability. Install into the dedicated network upgrade slot - no PCIe bandwidth consumed.

Can I expand the DS723+ later?

Yes. The DS723+ supports the DX517 expansion unit, adding 5 more drive bays for a total of 7 drives. This is unique among 2-bay NAS units - you can start small and grow without replacing your NAS.

Is the DS723+ good for Plex?

For direct play, yes. For transcoding, no - the AMD Ryzen R1600 has limited hardware transcoding capabilities. If Plex transcoding is important, choose the DS224+ with Intel Quick Sync instead.

How much RAM can the DS723+ support?

Up to 32GB DDR4 ECC memory. Stock configuration is 2GB - upgrade recommended for Docker containers or VM workloads. The DS723+ supports error-correcting (ECC) RAM for improved data integrity.

Does the DS723+ have NVMe slots?

Yes - two M.2 2280 NVMe slots on the bottom of the unit for SSD caching. This dramatically improves random I/O performance. Note: Unlike DS923+, NVMe drives can only be used for caching, not storage pools.

Verdict: Who Should Buy the DS723+?

✅ Buy DS723+ If…❌ Skip DS723+ If…
You want 10GbE in a compact formPlex transcoding is your priority
Planning to expand capacity laterBudget under $350
Running Docker containers or VMsYou need 4+ bays now
Need more than 6GB RAMSimple backup/file sharing only
Want NVMe caching capabilityIntel Quick Sync is important

Our recommendation: The Synology DS723+ is the most capable 2-bay NAS you can buy. Its combination of AMD Ryzen power, 10GbE readiness, NVMe caching, and expansion to 7 drives makes it unique in its class. Choose it if you want maximum features in a compact form, or if you plan to grow your storage over time. If Plex transcoding is your main use case, the DS224+ is a better (and cheaper) choice.
