Both Are Hardware-First Alternatives to Traditional NAS Brands

These two models compete for buyers who want more hardware than many conventional four-bay NAS systems provide at the same general size.

Both give you:

• Four SATA drive bays.
• DDR5 memory.
• Intel x86 processors.
• Hardware video acceleration.
• Multiple M.2 NVMe slots.
• Multi-gigabit Ethernet.
• Docker support.
• Virtual-machine support.

The useful question is therefore not whether one is “modern” and the other “traditional”. Both are modern. The question is which resource matters more: CPU/RAM/network peak speed or RAM included/NVMe count/dual-port symmetry.

CPU: Intel N150 vs Intel 8505

The TerraMaster F4-425 Plus uses Intel’s N150:

• 4 cores.
• 4 threads.
• Up to 3.6GHz.
• 6MB Smart Cache.
• 6W processor base power.
• Intel Graphics with 24 execution units.
• Intel Quick Sync Video.

The UGREEN DXP4800 Plus uses Intel’s 8505:

• 5 cores.
• 1 performance core + 4 efficiency cores.
• 6 threads.
• Up to 4.4GHz.
• 8MB Smart Cache.
• 15W processor base power.
• Intel UHD Graphics with 48 execution units.
• Intel Quick Sync Video.

On specification alone, the 8505 gives UGREEN more general CPU and graphics headroom. That matters most when several application workloads are active at once rather than when the NAS is simply serving files.

Do Not Turn Specifications into Fake Benchmarks

The 8505 has more cores/threads, higher turbo frequency and twice the graphics execution units, but a NAS is a whole system.

Real performance depends on:

• Drive layout.
• Filesystem.
• Container workload.
• Thermal limits.
• Network configuration.
• RAM allocation.
• Application version.

The safe conclusion is that UGREEN has the stronger compute platform—not that it is a fixed percentage faster in every task.

RAM: TerraMaster Starts Stronger, UGREEN Scales Further

This is one of the cleanest trade-offs.

• F4-425 Plus: 16GB DDR5 installed, one SO-DIMM slot, up to 32GB supported by TerraMaster.
• DXP4800 Plus: 8GB DDR5 installed, up to 64GB supported by UGREEN.

For a buyer who wants to install the NAS and immediately run a substantial Docker stack, TerraMaster’s 16GB base configuration is attractive.

For a buyer who expects heavier VMs, databases or many containers later, UGREEN’s 64GB ceiling gives it more long-term memory headroom.

Three M.2 Slots vs Two

TerraMaster’s unusual advantage is its three M.2 2280 NVMe slots.

TerraMaster specifies each as PCIe 3.0 x1. The three drives can be used for independent storage pools and TerraMaster also promotes three-drive NVMe RAID 5 configurations.

UGREEN provides two M.2 NVMe slots.

For most home NAS buyers, two NVMe drives are enough. Three become interesting if you want:

• A three-drive SSD pool.
• More separation between application data and cache.
• Additional fast local storage without sacrificing a SATA bay.

Do not confuse slot count with slot speed. TerraMaster’s M.2 slots are PCIe 3.0 x1, so expensive flagship NVMe drives cannot run at their headline desktop-PC speeds.

Networking: Dual 5GbE vs 10GbE + 2.5GbE

The F4-425 Plus has two 5GbE RJ45 ports.

The DXP4800 Plus has one 10GbE RJ45 port plus one 2.5GbE port.

For a single workstation that needs maximum straightforward bandwidth, UGREEN’s native 10GbE port is the cleaner solution.

TerraMaster’s dual 5GbE configuration is attractive for:

• Separate networks.
• Redundancy.
• Several simultaneous clients.
• SMB Multichannel on supported clients.
• Link aggregation where the complete network supports it.

Do not assume two 5GbE ports automatically create one ordinary 10Gbps connection. Multi-link performance depends on the protocol and client/network configuration.

Which Network Layout Is Better for a Creator?

If you edit large files directly from one 10GbE workstation, the UGREEN architecture is simpler:

Workstation 10GbE
      │
10GbE switch
      │
DXP4800 Plus 10GbE

TerraMaster can still deliver strong aggregate performance over dual 5GbE, but a single 10GbE port requires fewer assumptions about multichannel or link aggregation.

TOS 7 vs UGOS Pro

Both operating systems have matured rapidly.

TOS 7 provides:

• Btrfs and EXT4.
• TRAID/TRAID+ plus standard RAID layouts.
• Container Manager based on Docker Engine.
• Docker Compose multi-container projects.
• KVM-based virtual machines.
• App Center.
• Photo/media applications.
• Backup and cloud-sync tooling.

UGOS Pro provides:

• RAID/storage management.
• SMB/NFS/WebDAV/FTP/SFTP services.
• Docker and Docker Compose on supported models.
• Virtual Machine Manager on DXP models.
• Photo and media applications.
• Backup/sync functions.
• Remote-access tools.

Neither platform should now be dismissed as “hardware with unfinished software”. The more useful distinction is which interface, backup workflow and application set you prefer.

Docker: Both Are Strong Choices

TerraMaster’s TOS 7 Container Manager is based on Docker Engine and supports full image/container management plus docker-compose multi-container orchestration.

UGREEN also supports Docker and Docker Compose on compatible NASync models.

For a stack such as:

Home Assistant
+ MQTT
+ Immich
+ PostgreSQL
+ Vaultwarden
+ Nextcloud
+ media server
+ monitoring

either system can be a capable host. UGREEN has more CPU and maximum-memory headroom; TerraMaster starts with twice as much RAM and adds a third NVMe slot.

Virtual Machines: Both Now Have Proper Hypervisors

TOS 7’s current VMs application is a KVM-based hypervisor. TerraMaster recommends at least 4GB memory and supports Btrfs storage locations for VM disks.

UGREEN provides Virtual Machine Manager on its DXP platform.

For VM-heavy use, UGREEN’s 8505 and 64GB memory ceiling give it the stronger long-term platform.

For one or two light Linux VMs, the F4-425 Plus’s 16GB starting memory can be very practical without an immediate upgrade.

Plex and Jellyfin: Both Have Intel Quick Sync

Both processors support Intel Quick Sync Video.

TerraMaster explicitly lists H.264, H.265, MPEG-4 and VC-1 hardware transcoding on the F4-425 Plus, up to 4K60 under its specification.

UGREEN’s 8505 has 48 Intel graphics execution units versus 24 on the N150 and therefore offers the stronger underlying graphics hardware.

That still does not justify invented “number of 4K streams” claims. Real media performance depends on codec, tone mapping, subtitles, application version and whether the container can access the iGPU.

Direct Play Makes CPU Differences Much Less Important

If clients Direct Play the original files, both systems are far more powerful than required for basic media serving.

In that situation, storage capacity, network speed and software preference matter more than the difference between N150 and 8505.

RAID and Storage Flexibility

Both support the conventional four-bay layouts you would expect, including RAID 5/6/10.

TerraMaster additionally offers TRAID/TRAID+ on supported TOS configurations, providing a more flexible vendor-specific storage approach for expansion and mixed drive sizes.

UGREEN uses a more conventional standard-RAID model in UGOS Pro.

If mixed drive sizes or incremental expansion are central to your plan, verify the exact current TRAID migration rules rather than assuming it behaves identically to Synology SHR.

Four SATA Bays Remain the Long-Term Capacity Limit

Neither model gains an internal fifth SATA bay.

If you expect four large hard drives to become restrictive within a few years, compare six-bay systems before purchasing rather than relying on USB expansion later.

Power Consumption Is Very Similar in Vendor Tests

Current manufacturer figures are:

• F4-425 Plus: 45W with four specified 4TB Seagate NAS drives under read/write load; 14W with the drives hibernating.
• DXP4800 Plus: 42.36W during UGREEN’s drive-access test; 18.12W during drive hibernation.

These numbers use different vendor test methods, so they are not an apples-to-apples efficiency benchmark.

The important point is that neither system automatically carries a dramatic chassis-level power penalty relative to the other. The installed drives and workload matter heavily.

TerraMaster Publishes a Quiet Standby Figure

TerraMaster lists 20.9dB(A) for the F4-425 Plus using four SATA drives/SSDs in standby under its stated 1m test conditions.

UGREEN uses different acoustic marketing/test conditions, so direct dB comparisons are not useful.

In real use, hard-drive seek noise and furniture resonance can dominate both systems.

Physical Size

• F4-425 Plus: 150 × 181 × 219mm.
• DXP4800 Plus: 257 × 178 × 178mm.

The shapes are different: TerraMaster is taller/narrower and deeper, while UGREEN is longer and lower. Measure the shelf rather than comparing volume on paper.

Which Is Better for Home Assistant?

Either is excessive if the only requirement is Home Assistant backup storage.

Both become interesting when the NAS also hosts services around the smart home:

• MQTT.
• InfluxDB.
• Grafana.
• Node-RED.
• Frigate support services.
• Other Docker applications.

UGREEN’s stronger CPU and larger RAM ceiling suit a large combined stack. TerraMaster’s 16GB starting point can be better value if the workload is moderate and you do not want to buy memory immediately.

Which Is Better for a 10GbE Workstation?

The DXP4800 Plus is the simpler choice because it has a native 10GbE port.

The F4-425 Plus can use SMB Multichannel or other supported multi-link configurations across its two 5GbE ports, but that requires the client and network to participate correctly.

For one workstation, one cable and one 10GbE switch port, UGREEN is easier.

Which Is Better for NVMe-Heavy Workloads?

TerraMaster’s third M.2 slot is useful if you deliberately want a three-drive SSD layout.

Examples include:

• Three-drive NVMe RAID 5.
• SSD application storage plus separate cache.
• More VM/container storage without using SATA bays.

But each TerraMaster slot is PCIe 3.0 x1. If your main objective is the fastest possible single NVMe transfer, slot bandwidth matters more than the number of slots.

Complete-System Cost Can Reverse the Choice

Compare the build you actually need:

• NAS enclosure.
• Four hard drives.
• RAM upgrade.
• Two or three NVMe SSDs.
• UPS.
• 5GbE/10GbE switch.
• Client NIC or adapter.
• Independent backup storage.

A TerraMaster that already includes 16GB may be cheaper for a moderate Docker stack. A UGREEN that already includes native 10GbE may be cheaper for a creator workstation if TerraMaster would require additional network complexity.

TerraMaster F4-425 Plus vs UGREEN DXP4800 Plus: The Bottom Line

Choose the TerraMaster F4-425 Plus when you value hardware balance. It ships with 16GB DDR5, offers three M.2 slots, dual 5GbE, Btrfs/EXT4 and a mature TOS 7 Docker/KVM stack. For a buyer who wants a capable home lab without immediately purchasing RAM, it is very attractive.

Choose the UGREEN DXP4800 Plus when compute and single-link network performance matter more. The Intel 8505 gives it more CPU and graphics headroom, the system supports up to 64GB RAM, and native 10GbE is simpler for a high-speed workstation.

Neither wins every category. TerraMaster gives you more RAM now and more NVMe slots; UGREEN gives you more CPU/RAM headroom and faster single-port networking.

The right question is therefore not which specification sheet is longer. It is whether your bottleneck will be compute and 10GbE or NVMe layout and included RAM.
