If you want a six-bay NAS with built-in 10GbE, Thunderbolt 4 and room for NVMe storage, the UGREEN NASync DXP6800 Ultra is one option—not the only one. Compare it with the ASUSTOR Lockerstor 6 Gen3 AS6806T and QNAP TVS-h674 if you want another six-bay chassis; consider the eight-bay Synology DS1823xs+ if extra drive bays and Synology’s software ecosystem matter more than matching the UGREEN’s size. These are choices based on published specifications, not comparative performance testing.
For a home lab or small business, the practical question is which complete system fits the work: how many drive bays you need, which devices will connect, whether ECC memory is a requirement, what software features you rely on, and what the enclosure plus drives and expansion will cost. The models below offer different published hardware combinations, but their published specifications do not establish that one is faster, safer, quieter, easier or better overall.

Which alternative should you choose?
Start with the workload and the complete system you need, rather than choosing by processor name or maximum capacity. The most relevant trade-offs are built-in networking, memory type and capacity, NVMe expansion, bay count, software requirements and the cost of drives and other components.

In short, the UGREEN is a connectivity-led comparison point, ASUSTOR is notable for its listed ECC memory and port/M.2 combination, and QNAP offers a different software and expansion path. Synology is a larger-bay option rather than a like-for-like six-bay replacement. Those are ways to narrow the shortlist, not conclusions based on hands-on tests.
How the four NAS options compare
| Model | Bays and expansion | Memory and processing | Networking | Best comparison angle |
|---|---|---|---|---|
| UGREEN NASync DXP6800 Ultra | 6 SATA bays, 2 M.2 NVMe slots; PCIe Gen 4 x4 | Intel Core 5 120U; 8GB DDR5, listed as expandable to 96GB | 2×10GbE; 2×Thunderbolt 4 | Connectivity and CPU flexibility in a six-bay chassis. UGREEN product specifications |
| ASUSTOR Lockerstor 6 Gen3 AS6806T | 6 bays; 4 M.2 slots | AMD Ryzen V3C14; 16GB ECC DDR5 | 2×10GbE and 2×5GbE; USB4 | ECC memory, NVMe options and network ports. ASUSTOR model information |
| QNAP TVS-h674 | 6 SATA bays, 2 M.2 slots; PCIe Gen 4 | Core i3 or i5 options; up to 64GB on listed product information | Varies by configuration. The cited i3-16G configuration has 2×2.5GbE, with optional 10GbE through expansion. | QuTS hero and card-based expansion. QNAP product overview and i3-16G hardware specifications |
| Synology DS1823xs+ | 8 SATA bays, 2 M.2 slots | Consult Synology’s current configuration information | Verify the exact model configuration and expansion options | More SATA bays and Synology’s software ecosystem, in a larger capacity class. Synology product information and product manual |
Specifications are not the same as comparative results: the listed product information does not establish which model is faster, quieter, easier to maintain or more reliable. Treat vendor throughput figures, if encountered, as manufacturer claims rather than independent test results.
The table is a starting point, not a complete compatibility matrix. For each candidate, check six things before you decide: the number and type of bays; memory capacity and whether ECC is important to your workload; built-in network ports versus ports that require an add-in card; the number of M.2 slots and any shared expansion constraints; the software functions you need; and the total configured cost. A larger slot count or higher maximum memory figure does not automatically mean every option can be populated or used in the combination you intend.
What distinguishes the UGREEN DXP6800 Ultra?
UGREEN lists six SATA bays, two M.2 NVMe slots, dual 10GbE and two Thunderbolt 4 ports. It lists an Intel Core 5 120U processor and 8GB DDR5 memory, expandable to 96GB. That combination makes the model worth considering when a single NAS needs to connect to fast Ethernet clients and Thunderbolt-equipped devices, but suitability depends on the ports and software your actual workflow uses.
Think through the connection plan rather than counting port labels in isolation. If the devices that need access use 10GbE, the UGREEN’s two listed 10GbE ports are directly relevant. If a workflow also calls for Thunderbolt 4, the two listed ports may be a differentiator to investigate. Published information does not establish how every port combination behaves under a particular workload, so confirm the details for the devices and topology you plan to use.
UGREEN also states a maximum capacity of 208TB, calculated from six 32TB SATA drives and two 8TB M.2 drives. This is a manufacturer configuration claim for installed raw capacity—not the usable capacity of a RAID volume. RAID layout, formatting and filesystem overhead change the amount available for files; drive availability and compatibility should be verified for the chosen configuration.
That 208TB figure is useful as a description of the stated drive configuration, not as a promise that a buyer will have 208TB available for data. The six SATA drives and two M.2 drives represent separate installed capacities in the manufacturer’s calculation; the actual usable amount depends on how storage is configured. If you are estimating a project’s space needs, include the protection scheme and overhead in your own planning rather than shopping from the headline maximum alone.

When ASUSTOR’s hardware is a better fit
The AS6806T is a six-bay alternative with 16GB ECC DDR5, four M.2 slots, two 10GbE ports, two 5GbE ports and USB4 in the listed specifications. Its memory and port mix may fit workloads where ECC is a requirement or where multiple network speeds are useful. These specifications alone do not demonstrate a performance or reliability advantage.
ECC is a specification to weigh against your workload and operating requirements, not a universal reason to choose one system. If it matters to you, compare the ASUSTOR’s listed 16GB ECC DDR5 with the memory configuration and supported upgrades of the other exact models you are considering. Do not assume that memory capacity alone settles the question, or that a model without an ECC listing is interchangeable for a requirement that explicitly calls for it.
There is an important expansion detail: the ASUSTOR datasheet notes that installing its 10GbE NIC requires removing the M.2 daughterboard. Before relying on a particular combination of network and NVMe expansion, confirm the exact implementation and whether the configuration you want can operate simultaneously. Do not assume the slot count means every card and daughterboard can be used together.
This caveat matters when you map the AS6806T’s four M.2 slots and networking choices to a real system plan. The datasheet’s note concerns the 10GbE NIC and M.2 daughterboard; do not turn it into a broader unsupported claim about every port or configuration. Ask the manufacturer or consult the current documentation about the specific arrangement you intend to install before buying parts.

When QNAP’s expansion and software approach fits
The TVS-h674 provides six SATA bays, two M.2 slots and PCIe Gen 4 expansion. QNAP supports QuTS hero, its ZFS-based NAS operating system. The cited i3-16G hardware specification lists dual 2.5GbE and optional 10GbE through an expansion card, while the broader product family includes Core i3 and i5 options. Check the precise SKU: the network configuration should not be generalized across every TVS-h674 variant.
This model is a candidate for buyers who specifically want QuTS hero or want to plan networking through an expansion card. Account for the card and any associated compatibility or slot trade-offs when comparing total cost and expansion needs. The specifications provided do not establish an overall software advantage over the other systems.
The SKU distinction has a direct budgeting consequence. A buyer who needs 10GbE should not compare an i3-16G TVS-h674’s base dual 2.5GbE ports with a model that includes 10GbE and stop at the enclosure price. Include the required expansion card if the selected configuration calls for one, then verify its compatibility and whether it affects another planned expansion. Published information does not establish a universal card configuration or current price.

When to move up to an eight-bay Synology
The DS1823xs+ is not a direct six-bay substitute: it has eight SATA bays and two M.2 slots. It belongs in the comparison if your storage plan calls for more drive bays or if Synology’s software ecosystem is a deciding factor. Confirm current configuration and expansion details with Synology’s product information and manual before treating it as a fit for a specific workload.
More bays change the class of comparison. If six bays meet your foreseeable storage plan, the DS1823xs+ may be more system than you need; if the reason you are shopping is specifically to accommodate more SATA drives, it is worth including rather than forcing the decision to stay within six-bay enclosures. The published specifications do not support a claim that its software or hardware is superior, so treat the ecosystem as a preference to evaluate against your own required features.
Plan the whole system, not just the enclosure
A NAS enclosure may not include the drives needed for your storage plan. Check the selected model’s current drive-compatibility information and budget for appropriate disks. A 10GbE switch is not automatically necessary: one NAS and one workstation may be able to use a direct connection or existing equipment, while a network with multiple 10GbE clients may benefit from a switch. Verify the ports and topology you intend to use before buying networking gear.
Drive choice is a separate purchasing decision from enclosure choice. The cited product information gives bay counts and, for UGREEN, a stated capacity configuration, but current product information does not establish a complete drive-compatibility list for all four models. Check the current compatibility information for the exact NAS and drives, and choose capacity based on the amount of usable space your plan requires, not merely on the maximum installed-capacity claim.
Make a connection map before spending on networking: list the NAS, workstations and other clients that need fast access, note the network ports each device has, and decide whether a direct connection or existing equipment serves a one-NAS/one-workstation setup. A switch is conditional equipment for a multi-device 10GbE network, not a universal accessory. For the ASUSTOR and QNAP, include the documented or SKU-specific expansion requirements in that map.

A useful cost worksheet has one line for the enclosure at its current regional listing, one for the intended drives, and separate lines for memory upgrades, a required network card, a switch if the topology calls for one, and backup. This does not imply every buyer needs every item: some may use existing network equipment, and the switch may not be needed for a direct NAS-to-workstation connection. The purpose is to compare like with like and avoid letting an attractive enclosure price conceal required additions.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
Also distinguish the initial purchase from the recovery plan. A separate backup destination or service adds to system cost, but RAID inside the NAS is not a substitute for a copy outside it. Before choosing the least expensive configuration, decide what data must be recoverable and where another copy will live.
How to make the decision
- Set the bay requirement. Decide whether six SATA bays are sufficient or whether the DS1823xs+’s eight-bay capacity class is worth considering.
- List the devices that will connect. Identify whether clients need 10GbE, 5GbE, Thunderbolt 4 or USB4. Count ports and check whether add-in cards or daughterboards constrain other expansion.
- Decide whether ECC memory matters. If your workload or operating requirements call for ECC, the AS6806T’s listed 16GB ECC DDR5 is a relevant specification. Check each vendor’s current memory configuration and supported upgrades rather than assuming all memory is equivalent.
- Match the software to your work. Evaluate required features and your comfort with maintaining the chosen platform. The available specifications do not provide a complete software-feature comparison, so verify the particular backup, snapshot, virtualization or storage features you depend on with the manufacturer.
- Build a complete parts and recovery plan. Confirm drive compatibility, network topology, expansion parts and a separate backup destination before comparing the final system cost.
It can help to rank those requirements before looking at any one processor or advertised maximum. For example, someone who already has 10GbE workstations may put built-in 10GbE high on the list, while a buyer who has an explicit ECC requirement will want to verify memory first. Someone who needs QuTS hero should examine the QNAP SKU and expansion plan; someone whose storage design needs eight SATA bays should include Synology despite the larger chassis class. These are decision paths from published specifications, not claims about real-world speed.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.RAID is not a backup plan
RAID, snapshots, off-site copies and recovery procedures address different risks. RAID can provide storage redundancy depending on its level and failure conditions, but it does not by itself protect against accidental deletion, malware, theft, fire or loss of the NAS. Snapshots can help with some forms of recovery, while an off-site copy addresses risks that affect the primary location. Plan how to restore important data, not only how to keep a volume online.
UGREEN and ASUSTOR list RAID modes, and QNAP describes backup tooling, but the cited product information is not sufficient to compare the complete backup ecosystems of all four systems. Check model-specific software documentation for the exact snapshot, replication and recovery features you intend to use, and test a restore process.
Before deployment, identify which data needs a second copy, where that copy will be stored, and how you would restore it if the NAS or its location were unavailable. A mirror or other RAID arrangement may address certain drive-failure scenarios, but it is not the same as an off-site copy. Likewise, a snapshot is not automatically a complete backup strategy. Verify the features you plan to use on the chosen model and test the recovery steps rather than assuming a feature name guarantees a successful restore.

Frequently Asked Questions
What is the closest six-bay alternative to the UGREEN DXP6800 Ultra?
The ASUSTOR Lockerstor 6 Gen3 AS6806T and QNAP TVS-h674 are the closest cited six-bay comparisons. ASUSTOR stands out in the listed specifications for 16GB ECC DDR5, four M.2 slots and 10GbE/5GbE ports; QNAP offers QuTS hero support and PCIe Gen 4 expansion. Neither is established as an overall performance winner.
Does the UGREEN DXP6800 Ultra really have 208TB of usable storage?
UGREEN states a 208TB maximum based on six 32TB SATA drives plus two 8TB M.2 drives. That is a manufacturer configuration claim for installed raw capacity, not a promise of usable RAID capacity. RAID layout, formatting and filesystem overhead affect available space, and compatibility should be checked.
Recommended Free Tools
Do I need a 10GbE switch for one of these NAS systems?
Not necessarily. A single NAS and workstation may be able to use a direct connection or existing equipment. A 10GbE switch may be useful when multiple 10GbE clients need access. Check the ports and topology you plan to use before buying a switch.
Can I use all four M.2 slots and 10GbE on the ASUSTOR AS6806T at once?
The ASUSTOR datasheet notes that installing its 10GbE NIC requires removing the M.2 daughterboard. Confirm with current documentation or the manufacturer whether your specific desired combination can operate simultaneously; do not assume every slot and expansion option can be used together.
Which QNAP TVS-h674 configuration includes 10GbE?
Networking varies by SKU. The cited i3-16G specification lists dual 2.5GbE and optional 10GbE via expansion. Check the exact model listing and include any required expansion card and compatibility checks in your plan.
Is the Synology DS1823xs+ a direct replacement for a six-bay NAS?
No. It has eight SATA bays and two M.2 slots, so it is a larger-bay alternative for buyers whose storage plan or preference for Synology’s software ecosystem justifies considering that class of system.
