UGREEN NASync vs Synology for Home Assistant

Quick Summary (TL;DR):
For Home Assistant, the choice between UGREEN NASync and Synology is less about whether either NAS is “powerful enough” and more about what role the NAS should play. Both can provide SMB/NFS storage for Home Assistant OS backups. Synology DS925+ is the stronger backup-first platform because DSM has a mature storage, snapshot and backup ecosystem, including Hyper Backup, Snapshot Replication, Container Manager and Virtual Machine Manager. UGREEN DXP4800 Plus offers substantially stronger hardware for container-heavy use: Intel 8505, 8GB DDR5 expandable to 64GB, two M.2 slots, 2.5GbE plus 10GbE, official Docker support and Virtual Machine Manager on DXP models. For a dedicated Home Assistant installation, however, we would still run HAOS on a mini PC and use either NAS as a separate backup/storage server. Choose Synology when software maturity and backup workflow matter most; choose UGREEN when Docker, RAM, SSD expansion and faster networking are higher priorities.

Third-party SATA drives	Supported subject to compatibility guidance	Allowed on 2025 DS Plus with DSM 7.3, subject to policy
Best reason to buy	Hardware value and container headroom	Software maturity and storage management

The two NAS units are not exact equivalents in philosophy. UGREEN sells a more PC-like hardware platform; Synology puts more emphasis on DSM and its storage-management ecosystem.

Home Assistant Backups Do Not Need a Powerful NAS

Home Assistant OS can mount network storage using NFS or SMB/CIFS. When you create a network-storage target with the usage type Backup, Home Assistant can send manual and automatic backups directly to that NAS.

This means both UGREEN NASync and Synology are already suitable for the most important Home Assistant NAS use case before Docker or virtual machines enter the discussion.

For Home Assistant backup storage, the important features are:

Reliable SMB/NFS service.
Good disks and sensible RAID layout.
Snapshots or versioned recovery where possible.
UPS support.
Another backup copy away from the NAS.
A recovery process you understand.

10GbE, large RAM capacities and powerful CPUs do not make a Home Assistant backup more valid.

UGREEN DXP4800 Plus Hardware

The DXP4800 Plus is a four-bay x86 NAS running UGREEN’s UGOS Pro.

Intel Pentium Gold 8505.
5 cores / 6 threads.
Up to 4.4GHz.
8GB DDR5 installed.
Up to 64GB RAM supported by UGREEN.
Four SATA drive bays.
Two M.2 NVMe slots.
128GB SSD system disk.
One 2.5GbE Ethernet port.
One 10GbE Ethernet port.
USB-C and USB-A high-speed ports.
4K HDMI.

For Home Assistant backups alone, this is extreme overkill. For a NAS that will also run Docker, databases, photo services or several self-hosted applications, the extra hardware becomes useful.

Synology DS925+ Hardware

The DS925+ is also a four-bay NAS, but its specification is more conservative.

AMD Ryzen V1500B.
4 cores / 8 threads at 2.2GHz.
4GB ECC DDR4 installed.
Two memory slots.
Maximum 32GB memory.
Four SATA drive bays.
Two M.2 2280 NVMe slots.
Dual 2.5GbE Ethernet.
DX525 expansion support for up to nine total drive bays.

The DS925+ does not win the specification-sheet competition against UGREEN, particularly in networking and included RAM. Its value is more strongly tied to DSM.

For Simple Home Assistant Backups, They Are Functionally Equal

If your only requirement is:

Home Assistant OS
      ↓
SMB/NFS
      ↓
NAS backup share

then both platforms can do the job easily.

Home Assistant supports CIFS 2.1+ and NFS network targets. The NAS simply needs to expose a share, provide credentials where required, and remain reachable when the backup job runs.

Our step-by-step guide later in this series covers the exact configuration: Home Assistant Backups to UGREEN, Synology or QNAP NAS.

Synology Has the More Mature Backup Ecosystem

Synology’s biggest advantage is not that Home Assistant needs DSM. It is what DSM can do with the backup after Home Assistant has written it.

The DS925+ supports tools including:

Hyper Backup.
Snapshot Replication.
Synology Drive.
Cloud Sync.
USB Copy.
Btrfs snapshots.

Synology itself recommends a 3-2-1 backup approach. A Home Assistant backup stored on the NAS can therefore be included in a wider NAS protection strategy that sends another copy to USB storage, another NAS or supported cloud destinations.

Snapshots Add Protection Against Accidental Changes

Snapshot Replication uses Btrfs point-in-time copies for fast recovery from accidental deletion, file corruption and other unwanted changes.

The DS925+ supports up to 256 snapshots per shared folder and up to 2,048 snapshots across the system according to Synology’s current specifications.

A snapshot is not a replacement for an off-site backup, but it gives Synology a very polished local recovery layer.

UGREEN’s Advantage Is Hardware Headroom

UGREEN’s DXP4800 Plus starts with twice the RAM of the DS925+ and supports twice the maximum memory.

It also includes 10GbE alongside 2.5GbE. This does not help Home Assistant backups much, but it matters if the same NAS handles:

Large workstation backups.
Photo and video libraries.
Media editing.
Virtual-machine storage.
Multiple Docker services.
High-speed desktop access.

If the NAS will become a broader home server, UGREEN’s hardware advantage becomes much more relevant.

Docker: Both Platforms Support It

Docker support is no longer a meaningful reason to exclude either brand.

UGREEN officially supports Docker on its current DXP models. UGOS Pro provides a Docker application and supports Compose-style Projects through its graphical interface.

Synology’s Container Manager is supported on the DS925+ and provides Docker image and container management, including project deployment.

Which Is Better for Home Assistant-Adjacent Containers?

If you want to run:

Mosquitto MQTT.
Node-RED.
InfluxDB.
Grafana.
AdGuard Home.
Immich.
Vaultwarden.
Other Docker services.

UGREEN’s 8GB DDR5 starting configuration, higher memory ceiling and Intel CPU make it the more attractive hardware platform.

Synology can run the same class of workloads, but a DS925+ buyer planning heavier container use should budget for a RAM upgrade.

Should You Run Home Assistant Container on the NAS?

You can run Home Assistant Container on a suitable Docker-capable NAS, but remember what Container means.

Home Assistant Container does not include Supervisor or the Home Assistant Apps system. Services that HAOS would normally manage as Apps need to run separately.

For an experienced Docker user this may be perfectly acceptable. For someone who wants the full Home Assistant appliance experience, HAOS on dedicated hardware remains simpler.

What About Running Home Assistant OS in a NAS VM?

Both platforms have virtual-machine capability on the models discussed here. UGREEN states that its DXP models support Virtual Machine Manager, while Synology lists the DS925+ as compatible with Virtual Machine Manager.

That does not automatically make a Home Assistant OS VM on either NAS the same supported path as Home Assistant’s documented KVM/Proxmox, VMware or VirtualBox workflows. USB radio passthrough and VM boot configuration are also vendor-specific.

For this reason, we would treat NAS-hosted HAOS as an advanced configuration rather than the default recommendation.

The Failure-Domain Problem

Running Home Assistant on the same NAS that stores its backups creates an obvious dependency.

NAS fails
   ↓
Home Assistant stops
   ↓
Local Home Assistant backup location may also be unavailable

That is why our preferred architecture remains:

Dedicated HAOS mini PC
        ↓
UGREEN or Synology NAS
        ↓
Secondary/off-site backup

The NAS can reboot, update or rebuild storage without taking down the automation controller.

Drive Flexibility: UGREEN Is Simpler, but Synology Changed in DSM 7.3

UGREEN actively advertises support for third-party SATA HDDs and SSDs, subject to its compatibility guidance.

Synology’s 2025 Plus-series drive policy was initially much more restrictive, but the current DSM 7.3 policy is more flexible.

For 2025 DS Plus systems, Synology now allows third-party HDDs and 2.5-inch SATA SSDs that are not on the compatibility list to be used for new storage pools. Synology still recommends verified models and may limit support where an unlisted drive is responsible for a problem.

M.2 NVMe remains more restrictive: Synology’s current policy requires compatible/verified NVMe drives for new cache or M.2 storage-pool creation on the affected systems.

So the blanket statement that the DS925+ requires Synology-branded hard drives is no longer accurate under DSM 7.3.

Synology Memory Policy Is Also More Controlled

The DS925+ ships with 4GB ECC DDR4 and supports up to 32GB. Synology recommends its own memory modules and states that full warranty or technical support may not be provided where non-Synology memory expansion is involved.

UGREEN ships the DXP4800 Plus with 8GB DDR5 and supports up to 64GB, while directing buyers to its compatibility list before upgrading.

For users planning many containers or virtual machines, UGREEN’s larger supported memory ceiling is a practical advantage.

NVMe: Same Slot Count, Different Philosophy

Both units provide two M.2 2280 NVMe slots, but how you use those slots differs.

UGREEN presents its M.2 slots as part of the general storage/performance architecture and supports third-party devices according to its compatibility guidance.

Synology supports M.2 cache and storage pools on the DS925+, but its current policy is much stricter about which NVMe models can be used to create those pools.

If you plan to put Docker application data or VM storage on NVMe, check the exact approved-drive policy before buying SSDs.

Networking: UGREEN Wins the Specification Sheet

UGREEN gives you one 2.5GbE port and one 10GbE port. Synology gives you two 2.5GbE ports.

For Home Assistant backups, neither is a bottleneck. Even 1GbE is more than adequate.

10GbE becomes valuable when the same NAS serves large media files, workstation backups, VM images or high-speed multi-user workflows.

Do not pay a networking premium purely for Home Assistant.

RAID and Storage Expansion

Both four-bay NAS units support the common RAID layouts needed for home storage.

Synology also offers Synology Hybrid RAID (SHR), which can make future mixed-capacity expansion easier than traditional fixed RAID layouts.

The DS925+ supports the DX525 expansion unit and can grow to nine drive bays. UGREEN’s DXP4800 Plus is a self-contained four-bay system without an equivalent external expansion bay in its specification.

If long-term disk expansion matters more than CPU performance, this is a meaningful Synology advantage.

Software Maturity vs Hardware Value

This is the core trade-off.

Priority	Better fit	Reason
Home Assistant backup target	Either	Both support SMB/NFS
Most mature backup ecosystem	Synology	Hyper Backup, Snapshot Replication, DSM tooling
Docker-heavy use	UGREEN	More included RAM and stronger hardware headroom
10GbE out of the box	UGREEN	Built-in 10GbE + 2.5GbE
ECC memory by default	Synology	DS925+ ships with 4GB ECC DDR4
Maximum RAM	UGREEN	64GB vs 32GB
External drive-bay expansion	Synology	DX525 supported
Broad SATA drive freedom	UGREEN	Simpler third-party drive positioning

Which Is Easier to Recover After a Home Assistant Failure?

If Home Assistant runs on a separate mini PC, both are equally straightforward as backup targets.

Replace or reinstall the Home Assistant machine.
Boot Home Assistant OS.
Restore the Home Assistant backup stored on the NAS.
Reconnect radios or network devices as required.

Synology’s advantage appears when you need to recover the NAS data itself because DSM offers a broader, mature set of snapshot and backup tools around the Home Assistant files.

Which Is Better for a Docker-First Home Server?

If your plan is:

NAS
├── Home Assistant backups
├── MQTT
├── InfluxDB
├── Grafana
├── Immich
├── DNS
└── Other Docker services

the DXP4800 Plus is the more attractive hardware starting point. It already has 8GB RAM, can expand to 64GB and includes 10GbE.

The DS925+ can run the same general class of container workloads, but the 4GB base configuration makes a RAM upgrade more likely.

Which Is Better for a Backup-First NAS?

If the NAS’s main job is protecting Home Assistant, PCs, photos and family documents, the DS925+ has the stronger argument.

You are buying into DSM’s storage and recovery tools rather than chasing unused CPU capacity. Hyper Backup, Snapshot Replication, SHR and the mature DSM interface all fit the backup-first use case.
