If you want six drive bays with fast built-in networking, the UGREEN NASync DXP6800 Ultra is a strong fit on paper: its listed hardware includes dual 10GbE and two Thunderbolt 4 ports. Consider the ASUSTOR Lockerstor 6 Gen3 AS6806T if ECC memory and additional M.2 and network options matter more; the QNAP TVS-h674 if QuTS hero and PCIe expansion suit your plans; or the eight-bay Synology DS1823xs+ if extra SATA capacity and Synology’s software ecosystem are priorities. These are comparisons of published specifications, not hands-on performance verdicts.
Choose by workload and total configured cost—not by CPU name or bay count alone. The enclosure may not include storage drives, and the right network setup depends on how many devices need high-speed access.
At a glance: which alternative fits your workload?
| Model | Drive and expansion layout | Memory and processor | Networking | Consider it when… |
|---|---|---|---|---|
| UGREEN NASync DXP6800 Ultra | 6 SATA bays, 2 M.2 slots, PCIe Gen 4 x4 | Intel Core 5 120U; 8GB DDR5, listed expandable to 96GB | 2×10GbE; 2×Thunderbolt 4 | You want this combination of six bays, high-speed wired networking and Thunderbolt 4. UGREEN’s product page lists these 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 and more M.2 or network connections are priorities. Check the data-sheet note about the 10GbE NIC and M.2 daughterboard before planning a simultaneous configuration. ASUSTOR’s product information is the place to verify the exact implementation. |
| QNAP TVS-h674 | 6 SATA bays, 2 M.2 slots, PCIe Gen 4 expansion | Core i3 or i5 options; up to 64GB on listed product information | Varies by SKU. The cited i3-16G configuration has 2×2.5GbE, with 10GbE available through an expansion card. | You want QuTS hero and a card-based expansion path. Confirm the exact SKU before assuming it has 10GbE built in. See QNAP’s TVS-h674 overview and i3-16G hardware specifications. |
| Synology DS1823xs+ | 8 SATA bays, 2 M.2 slots | Consult Synology’s current configuration information | Verify the exact SKU and expansion options | You are open to a larger, eight-bay system and value Synology’s software ecosystem. It is not a direct six-bay size match. See Synology’s product page and product manual. |
The closest like-for-like comparison is among the three six-bay units. They differ less in the basic question of how many SATA drives fit than in the available memory, network ports, M.2 slots, and expansion choices. Synology belongs in the shortlist if eight bays are useful and you are willing to compare a larger capacity class. None of these specification differences alone establishes which unit performs best for a particular application.
What the DXP6800 Ultra offers—and what its capacity figure means
UGREEN lists the DXP6800 Ultra as a six-SATA-bay NAS with two M.2 NVMe slots, dual 10GbE, two Thunderbolt 4 ports, and a PCIe Gen 4 x4 expansion slot. Its listed memory is 8GB DDR5, expandable to 96GB. Those specifications make the model a plausible match for a home lab or small business that expects to connect fast clients or add hardware, but published specifications alone do not establish real-world throughput or compatibility for a particular workload.

UGREEN also states a maximum capacity of 208TB, based on six 32TB SATA drives and two 8TB M.2 drives. Treat that as the manufacturer’s raw installed-capacity configuration—not usable RAID capacity. RAID layout, formatting, filesystem overhead, drive availability and the role assigned to the M.2 drives all affect the space you can actually use. Do not select a NAS on the assumption that this headline number is what will be available for files.
The two M.2 slots should also be treated as part of a planned configuration, not as guaranteed extra file capacity. Decide what role you want the NVMe drives to play, then check the current manufacturer documentation for supported configurations and compatibility. UGREEN’s product page lists the slot count and states the 208TB capacity claim, but it does not establish that every possible arrangement is appropriate for every use case.
For the exact configuration and manufacturer claims, consult the UGREEN NASync DXP6800 Ultra product page. Check current regional availability, included memory, drive compatibility and expansion details before buying.

When the ASUSTOR Lockerstor 6 Gen3 is the closer fit
The AS6806T keeps the comparison at six bays but changes the emphasis: its listed configuration includes 16GB ECC DDR5, four M.2 slots, dual 10GbE, dual 5GbE and USB4. That makes it worth considering if ECC memory or multiple NVMe and network options matter to your design. The hardware list is not a performance test, and more ports or slots do not automatically mean they can all be used simultaneously in every configuration.
In particular, ASUSTOR’s data sheet notes that installing the 10GbE NIC requires removal of the M.2 daughterboard. The practical implications depend on the exact implementation, so confirm whether your intended 10GbE and M.2 configuration can coexist before treating all listed connections as available at once. Review the AS6806T product information and its manufacturer downloads and data sheet.
ECC memory is a specification distinction, not a blanket guarantee that a system is safer or more reliable for every use. Decide whether it is relevant to your workload and operating requirements rather than paying for a feature solely because it appears on a spec sheet. If ECC is a requirement, confirm the exact model’s supported memory configuration and do not assume that the presence of ECC changes the need for independent backups or recovery planning.
For a buyer choosing between UGREEN and ASUSTOR, the useful question is therefore not simply “which has more ports?” Write down the connections and memory features you will actually use. UGREEN’s listed combination includes Thunderbolt 4 and dual 10GbE, while ASUSTOR lists USB4, dual 10GbE, dual 5GbE, ECC memory and four M.2 slots—with the daughterboard caveat. Compare the value of those distinct features against the cost and expansion plan for your own setup.

When QNAP’s TVS-h674 is the better-shaped option
The TVS-h674 provides six SATA bays, two M.2 slots and PCIe Gen 4 expansion, and QNAP supports QuTS hero. The key configuration detail is networking: the cited TVS-h674-i3-16G hardware sheet lists dual 2.5GbE, with 10GbE available through an expansion card. Do not assume every TVS-h674 SKU has the same processor, memory or network ports; verify the specific model you are considering.
This card-based path may suit a buyer who wants to choose expansion hardware rather than rely on a particular built-in port configuration. It also makes the final system cost and slot plan dependent on the selected card and other expansion needs. QNAP’s product information describes backup tooling, but the available information here is not enough to compare the full backup and software ecosystems across vendors. Check the TVS-h674 overview and the i3-16G hardware page for current configuration details.
QuTS hero is a reason to investigate this model, not a substitute for checking whether its software and maintenance approach fits your organization. Confirm the software version and capabilities that matter to you, as well as whether the selected SKU and any expansion card meet the hardware requirements of your plan. QNAP’s product information identifies QuTS hero, M.2 slots and PCIe Gen 4 expansion; it does not support a feature-by-feature verdict against the other vendors.
When comparing the TVS-h674 to the DXP6800 Ultra, account for the network difference in the cited QNAP configuration. A dual-2.5GbE base configuration and optional 10GbE card are not the same purchase as a NAS listing dual 10GbE ports as built-in hardware. If you want 10GbE on QNAP, verify the card’s compatibility, whether the necessary expansion capacity remains available for other plans, and the extra cost before treating the systems as equivalent.
When to move up to the eight-bay Synology DS1823xs+
The DS1823xs+ is for buyers willing to compare a different capacity class. It has eight SATA bays and two M.2 slots, rather than the six SATA bays of the DXP6800 Ultra, AS6806T and TVS-h674. That additional bay count may matter if your storage plan calls for more drive positions, while Synology’s software ecosystem may be a deciding factor for someone already comfortable with it. Verify the exact hardware configuration and expansion choices in Synology’s current product information and manual.
Because it is an eight-bay system, compare total configured cost and physical capacity needs rather than treating it as an interchangeable six-bay alternative. The available product information does not establish a complete, like-for-like software or performance comparison with the other models.
Moving to eight bays is not automatically the right choice just because more positions are available. First estimate how many drive positions your planned configuration needs, and decide whether the added capacity class is worth considering alongside the enclosure, drives and backup destination. Synology’s product information identifies the DS1823xs+ as an eight-bay alternative, but does not establish its current price or quantify how its total cost compares with the six-bay systems.

Home lab or small business: match the feature to the job
For a home lab, start by listing the interfaces and expansion options that are actual requirements rather than aspirational extras. A setup with a workstation that needs a fast connection may make the UGREEN’s listed dual 10GbE and Thunderbolt 4 ports relevant. A lab plan centered on ECC memory or multiple M.2 devices may make the ASUSTOR specification set more compelling, but its NIC/daughterboard constraint needs to be resolved first. If you intend to add a network card, the QNAP’s PCIe expansion path is worth examining, with the card and exact SKU included in the plan.

The manufacturer information cited here does not establish which vendor has the easiest management experience or the strongest complete software ecosystem, so test those needs against current documentation and software versions rather than assuming a brand or hardware spec answers them.
For either audience, separate the NAS selection into three questions: where will files be stored, how will clients connect, and how will files be recovered if something goes wrong? Bay count and drive configuration address the first; built-in or add-on networking affects the second; a separate backup and restoration plan addresses the third. Treating these as separate decisions avoids asking one specification—such as 10GbE, ECC or an additional bay—to solve a different problem.
How to choose: work through the system, not just the enclosure
- Set the bay requirement. Decide how many SATA drive positions your current plan needs and whether you expect to grow into more. If six bays are the target, compare the DXP6800 Ultra, AS6806T and TVS-h674. If you want eight SATA bays, consider the DS1823xs+ as a different-sized option.
- Map memory to the workload. Compare the listed memory and expansion limits, and decide whether ECC is a requirement. The cited configurations list 8GB DDR5 expandable to 96GB for UGREEN, 16GB ECC DDR5 for ASUSTOR, and up to 64GB on QNAP product information. These figures are not proof of workload performance; verify current configuration and compatibility for the exact unit.
- Draw the network path. List which clients need high-speed access and how they will connect. UGREEN lists dual 10GbE; ASUSTOR lists dual 10GbE and dual 5GbE, subject to the daughterboard constraint noted above; the cited QNAP i3-16G configuration has dual 2.5GbE and optional 10GbE expansion. A 10GbE switch can help when multiple 10GbE devices need to communicate through a network, but it is not universally required. A single NAS and workstation may be served by a direct link or existing equipment, depending on the setup.
- Check slot and port conflicts. Count the M.2 slots, PCIe needs and any hardware that may occupy or displace another component. Do not assume advertised options can all operate at once; verify the manufacturer’s current documentation for the intended combination.
- Choose software features you will actually use. QuTS hero is a specific reason some buyers may examine QNAP, while Synology’s software ecosystem may matter to existing users. The facts available here do not establish a full software-feature comparison, so confirm that the required applications, management features and maintenance workflow are supported on the exact model and software version.
- Calculate the complete system cost. Include the enclosure, drives, any memory or expansion card you plan to add, network gear if needed, and a separate backup destination. Current local prices and exact compatibility were not established in the cited product information; check them for your region and selected SKU.
Cost and pre-purchase checks
There is no verified current price comparison in the cited product information, so a responsible shortlist should use a same-day, same-region quote rather than assume one brand is the cheaper option. Compare the complete configuration you would actually deploy. An enclosure-only price can omit the cost of drives; a QNAP plan that needs 10GbE should account for the optional expansion card; and a multi-device 10GbE network may call for a switch. A switch is conditional, however: a single NAS and workstation may use a direct connection or existing network equipment, depending on the setup.
Make a simple bill of materials before choosing: exact NAS SKU, included memory, intended SATA and M.2 drives, any memory upgrade or card, network equipment if required, and a separate backup destination. Do not assume a drive is compatible merely because it uses a familiar connector. Check the manufacturer’s current compatibility information for the particular model and intended drive use. Then check local availability, product lifecycle, current software version and the exact bundled configuration; these details can change and are not settled by a model name alone.
For the network line item, distinguish ports on the NAS from the rest of the path. A device with 10GbE ports does not by itself establish that every client can use 10GbE; identify which clients need the connection and whether your existing network equipment or a direct link serves that topology. Add a switch only if the planned number of devices and network arrangement call for one. This keeps a fast-port specification from turning into an unnecessary accessory purchase.
Likewise, price M.2 and PCIe plans as a complete layout. The products have different slot counts and expansion approaches, and ASUSTOR’s data sheet includes a specific daughterboard constraint. For QNAP, optional 10GbE expansion changes the configuration and cost from the cited dual-2.5GbE base model. Verify that the selected card, drives and intended slot arrangement are supported together before checkout.

Plan storage and backups as separate decisions
A NAS enclosure purchase may require separate drives, so check what is included and whether the selected SATA or M.2 drives are supported for your intended use. Compatibility lists and supported configurations can change; consult the manufacturer’s current information for the exact model rather than relying on a drive’s connector type alone.
RAID and backup solve different problems. RAID is a storage-layout choice; it does not by itself provide an independent copy of files or a recovery plan. Snapshots, off-site copies and tested restoration procedures address other parts of data protection. Decide how you will recover from accidental deletion, device failure or loss of access, and verify the model-specific software features that support that plan. The available information identifies RAID modes for UGREEN and ASUSTOR and backup tooling from QNAP, but does not establish enough detail to rank each vendor’s entire backup ecosystem.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Common buying mistakes to avoid
- Equating raw capacity with usable space. UGREEN’s 208TB figure is based on a stated drive configuration before accounting for RAID, formatting and overhead.
- Assuming a network port is included on every SKU. QNAP’s cited i3-16G sheet lists dual 2.5GbE and optional 10GbE expansion; check the exact TVS-h674 configuration.
- Counting every slot and port as simultaneously available. ASUSTOR’s data sheet notes that installing its 10GbE NIC requires removal of the M.2 daughterboard; resolve the intended combination with current documentation.
- Buying a switch by default. A switch is conditional on how many high-speed devices need network access; some one-NAS/one-workstation arrangements may use a direct link or existing equipment.
- Choosing by CPU label alone. The supplied specifications do not prove which system is faster for your applications. Consider software requirements, memory, connectivity, expansion and the complete system cost.
- Assuming a specification is a complete recommendation. ECC, more M.2 slots, Thunderbolt 4, PCIe expansion and an extra pair of bays are each useful only if they match the intended setup; none is a substitute for verifying compatibility and the complete configuration.
- Forgetting the recovery plan. RAID does not replace a separate backup. Include the backup destination and restoration process when evaluating both budget and maintenance needs.
- Comparing different SKUs as if they were identical. Confirm processor, memory and built-in network ports for the exact TVS-h674 configuration, and verify included memory and regional availability for any model before ordering.
What the published specifications do—and do not—settle
The manufacturer pages and data sheets establish selected hardware features and configurations. They do not establish that one NAS is quieter, faster, easier to maintain, more reliable, safer or cheaper overall. Nor do they provide a complete, current comparison of software, compatibility, lifecycle, regional prices or all possible simultaneous port and expansion combinations. Treat the recommendations here as conditional matches to published specifications, and verify those practical details for your location and intended workload before ordering.
This is a specification-based comparison, not a hands-on review: no device testing, performance validation or ownership experience is represented here. Published throughput claims, if encountered on manufacturer pages, should be read as vendor-supplied claims unless independently tested. Use the model’s current documentation to settle details that can vary by SKU, region, software version or installed expansion hardware.
Frequently Asked Questions
Which NAS is the closest alternative to the UGREEN DXP6800 Ultra?
The ASUSTOR Lockerstor 6 Gen3 AS6806T and QNAP TVS-h674 are the closest alternatives by bay count: each is a six-bay option. Their hardware emphasis differs, so compare memory, network configuration, M.2 slots, expansion and software needs rather than treating them as identical replacements.
Is the UGREEN DXP6800 Ultra’s 208TB capacity usable storage?
No. UGREEN’s 208TB figure is a manufacturer-stated raw installed-capacity configuration using six 32TB SATA drives and two 8TB M.2 drives. RAID layout, formatting, filesystem overhead, drive availability and how the M.2 drives are used affect usable capacity.

Does every QNAP TVS-h674 have 10GbE built in?
No such blanket assumption is supported. The cited TVS-h674-i3-16G hardware sheet lists dual 2.5GbE, with 10GbE available through an expansion card. Verify the exact SKU and card configuration you plan to buy.
Can the ASUSTOR use its 10GbE NIC and M.2 daughterboard together?
The ASUSTOR data sheet notes that installing the 10GbE NIC requires removal of the M.2 daughterboard. Check the current data sheet and manufacturer information for the exact implementation before planning to use both in a particular configuration.
Do I need a 10GbE switch with one of these NAS devices?
Not necessarily. A switch can be useful when multiple 10GbE devices need network access, but a one-NAS/one-workstation arrangement may use a direct link or existing network equipment, depending on the setup.
Recommended Free Tools
Does RAID replace a backup?
No. RAID is a storage-layout choice, not an independent copy or complete recovery plan. Plan separately for backups, snapshots where appropriate, off-site copies and tested restoration, and verify the selected model’s software supports your approach.
Should I choose the Synology DS1823xs+ instead of a six-bay NAS?
Consider it if eight SATA bays and Synology’s software ecosystem fit your priorities. It is a different capacity class, not a direct six-bay match; check its current configuration, expansion choices and total system cost.
The Bottom Line
Choose the DXP6800 Ultra if its listed six bays, dual 10GbE and Thunderbolt 4 match your planned connections. Consider the ASUSTOR AS6806T for its listed ECC memory and broader M.2 and network options, while checking the NIC/daughterboard constraint; consider QNAP if QuTS hero and card-based expansion fit, after confirming the SKU and any 10GbE card; and look at the eight-bay Synology DS1823xs+ if extra drive positions and its software ecosystem justify comparing a larger system. Before ordering, verify local price, included memory, drive compatibility, slot and port combinations, and the cost of drives, network gear if needed, and a separate backup destination. These are conditional recommendations from published specifications, not tested performance rankings.
