Which UGREEN 4-Bay NAS Fits Your Workload?

DH4300 Plus for Backup, Photos, and Family Storage

The UGREEN NASync DH4300 Plus is the lower-cost route to four SATA bays. At its listed retail price, it costs $290 less than the DXP4800 Plus before drives.

It fits households that need automatic phone and computer backups, shared documents, photo management, and a central media library. Its 2.5GbE connection can approach roughly 280 MB/s during suitable large-file transfers when the drives, client, switch, and cabling can keep up.

The DH4300 Plus also has a meaningful power advantage. 22.89W during drive access and 7.23W during drive hibernation, compared with 42.36W and 18.12W for the DXP4800 Plus.

Using eight hours of drive access, sixteen hours of hibernation, and electricity at $0.18 per kWh, that works out to approximately $20 per year for the DH4300 Plus and $41 for the DXP4800 Plus. Installed drives, applications, network activity, and whether the disks can enter hibernation will affect the final result.

The DH4300 Plus supports Docker, but its ARM processor and fixed 8GB of memory make it better suited to light, ARM-compatible containers. It does not support virtual machines, and its memory cannot be expanded.

There are no M.2 slots, so container data, application databases, and other active workloads remain on the SATA storage pool. The ARM processor also lacks Intel Quick Sync. Media clients should use Direct Play whenever possible instead of relying on repeated server-side transcoding.

Choose the DXP4800 Plus instead if you need virtual machines, expandable memory, M.2 storage, 10GbE, broader x86 container compatibility, or Intel Quick Sync.

DXP4800 Plus for the Best Balance of Storage and Applications

The UGREEN NASync DXP4800 Plus is the best-balanced current 4-bay model for most power users.

{{UGPRODUCT}}

Its Intel Pentium Gold 8505 includes Intel Quick Sync, which supports compatible hardware-transcoding workloads when Plex is running through Docker with graphics access configured correctly and an active Plex Pass. Our UGREEN NAS Plex setup guide covers the complete configuration.

The installed 8GB of DDR5 memory can be expanded to 64GB. That gives Docker containers, virtual machines, indexing, and file services more room to run together than the fixed-memory DH4300 Plus.

Two M.2 NVMe slots can be used for SSD caching or a separate SSD storage pool. Cache can improve repeated access to suitable data, while a dedicated SSD pool is the stronger option for virtual-machine disks, container databases, and active project files that need consistently low latency.

The DXP4800 Plus also includes one 10GbE port and one 2.5GbE port. A creator workstation can use the 10GbE connection while the rest of the household or office remains on 2.5GbE.

A 10GbE link has a theoretical ceiling of 1.25 GB/s. Capable systems can approach roughly 1 GB/s during practical large-file transfers, but four NAS HDDs in RAID 5 generally deliver around 600 to 700 MB/s under favorable sequential conditions. SSD storage, several simultaneous clients, or both are needed to make fuller use of the network connection.

The DXP4800 Plus is enough for a broad mix of storage and applications. The next model is justified when processor or memory demand becomes the actual constraint.

DXP4800 Pro for Heavier Containers and Virtual Machines

The UGREEN NASync DXP4800 Pro replaces the Pentium Gold 8505 with an Intel Core i3-1315U and raises the memory ceiling from 64GB to 96GB.

That difference matters when the NAS will run several containers, virtual machines, databases, media processing, photo indexing, and multi-user file transfers at the same time. A storage-only workload will not benefit enough from the faster processor to justify the upgrade.

At the listed retail prices, the Pro costs $70 more than the DXP4800 Plus. That premium buys additional processor and memory headroom. It does not buy more SATA capacity.

The Pro retains Intel Quick Sync, two M.2 slots, one 10GbE port, and one 2.5GbE port. It is therefore the better four-bay choice when Plex hardware transcoding must run alongside heavier self-hosted services.

Both models have four SATA bays and two M.2 slots. Buy the Pro for compute and memory headroom, not because its storage pool is larger.

The DXP4800 GT takes the design in a different direction. It prioritizes network and storage flexibility instead of Intel media processing.

DXP4800 GT for Dual 10GbE, ECC, and U.2 Storage

The UGREEN NASync DXP4800 GT uses an AMD Ryzen Embedded R2514 processor and includes two 10GbE ports. It fits storage-focused homelabs, multiple high-speed workstations, and workloads where aggregate network throughput is a more important constraint than Intel Quick Sync.

Two 10GbE ports do not turn one ordinary file transfer into a 20Gbps connection. A single TCP session remains limited by one link. Multiple clients can use the two ports concurrently, while configurations such as SMB Multichannel or iSCSI multipathing can use multiple paths when the client and software are set up for them.

The GT supports memory expansion to 64GB and can use ECC memory, but the included 8GB module is standard non-ECC memory. Buyers who need ECC must purchase and install compatible ECC modules.

ECC memory can correct certain single-bit memory errors and detect certain multi-bit errors, reducing the risk that a memory fault alters data while it is being processed. That protection is most relevant to long-lived archives, databases, virtual machines, and other workloads where data integrity matters more than the lowest purchase price.

ECC does not provide end-to-end data protection. It cannot replace RAID maintenance, checksums, snapshots, or an independent backup.

The GT also has two internal M.2 slots and supports compatible U.2 NVMe SSDs in front bays 1 and 2. A U.2 drive replaces the SATA drive in that bay, so U.2 does not increase the enclosure beyond four front storage bays. Its value is endurance and sustained storage performance for databases, virtual machines, or active project data.

The AMD processor does not provide the Intel Quick Sync path used by the DXP4800 Plus and Pro. Plex can still use Direct Play, but buyers choosing a model specifically for Intel Quick Sync hardware transcoding should select one of the Intel systems.

Choose the GT when networking, ECC, or U.2 storage drives the purchase. Choose the Pro when processor performance, a 96GB memory ceiling, and Intel Quick Sync matter more.

Understand the Maximum-Capacity Numbers

The DH4300 Plus supports up to 128TB of raw SATA capacity using four 32TB drives.

The DXP4800 Plus, DXP4800 Pro, and DXP4800 GT are listed with up to 144TB of total supported raw capacity. That figure combines four 32TB SATA drives with two 8TB M.2 SSDs:

4 × 32TB SATA + 2 × 8TB M.2 = 144TB raw capacity

The 144TB figure does not describe one 144TB RAID pool. The SATA drives form their own storage configuration. M.2 SSDs can provide cache or a separate SSD storage pool, depending on how they are configured. SSD capacity assigned to cache does not become additional general file-storage capacity.

Usable space will also be lower than raw capacity after RAID, unit conversion, the filesystem, and system reservations.

Budget for the Complete Four-Bay System

All current UGREEN NAS enclosures are sold diskless. The drives are purchased separately, so the enclosure price is only one part of the budget.

A complete four-bay plan can include:

• The NAS enclosure
• Two to four matched CMR NAS hard drives
• M.2 or U.2 SSDs if the workload needs them
• Memory upgrades for containers, virtual machines, or ECC
• A UPS for controlled shutdown during a power outage
• An independent backup
• A 10GbE client adapter, switch, and suitable cabling
• Electricity
• A replacement-drive contingency

Before ordering storage or memory, use the UGREEN compatibility list to identify validated HDDs, SSDs, RAM, and UPS models.

RAID keeps data available after the supported number of drive failures. It does not restore files lost to deletion, corruption, ransomware, theft, or damage to the entire NAS. Keep an independent copy of irreplaceable data.

When a Six-Bay or Eight-Bay NAS Is the Better Buy

Do not force the purchase into four bays when the capacity calculation already says otherwise.

Start with a six-bay or eight-bay NAS when:

• Your projected library does not fit four drives after RAID and free-space headroom
• You want RAID 6 without giving half of a four-drive array to parity
• You expect storage growth beyond four SATA drives
• Replacing every installed drive with a larger one would be the only expansion route
• Several high-speed users need more aggregate HDD performance
• Surveillance, virtual machines, or creative workloads require more storage and drive-level throughput than four bays can provide

For example, four 8TB drives in RAID 6 provide 16TB of decimal usable capacity. Six 8TB drives in RAID 6 provide 32TB. The larger enclosure doubles usable capacity in that example while preserving tolerance for any two drive failures.

If four bays meet the plan, choose the model according to the application, memory, media, and network requirements above. If they do not, browse and filter UGREEN NAS models by bay count, network speed, processor, and storage support before buying drives.
