The catch
ASUSTOR Nimbustor 4 Gen2
The full double-parity array is limited by four SATA bays
Side by side
ASUSTOR AS5404T vs UGREEN DXP8800 Plus Compared: More NVMe drives fit in ASUSTOR, and more SATA drives fit in UGREEN
Quick verdict
The AS5404T fits a design that needs three or four internal NVMe drives and is fine with four SATA bays. The DXP8800 Plus fits when six to eight SATA drives or native 10GbE are fixed requirements. These enclosures expand different parts of the storage plan.
Before you buy
Why, and what it costs you
Eight hard drives and four NVMe drives point different ways
SATA count doubles on DXP8800 Plus, and onboard NVMe count doubles on AS5404T.
Where this comes from
The inventory to fit is eight SATA drives or four onboard NVMe devices. DXP8800 Plus has eight and two connectors respectively, and AS5404T has four and four.
The catch
UGREEN NASync DXP8800 Plus
No more than two onboard M.2 sockets
ASUSTOR Nimbustor 4 Gen2
- Why pick it
- Have four internal NVMe sockets next to four SATA bays
- Live with a documented 16 GB memory ceiling
- The catch
- The full double-parity array is limited by four SATA bays
UGREEN NASync DXP8800 Plus
- Why pick it
- Fit as many as eight SATA drives in one enclosure
- Get native 10GbE with no Ethernet card to add
- The catch
- No more than two onboard M.2 sockets

In practice
Differences you will notice
Eight hard drives and four NVMe drives point different ways
SATA count doubles on DXP8800 Plus, and onboard NVMe count doubles on AS5404T.
How we worked this out
The inventory to fit is eight SATA drives or four onboard NVMe devices. DXP8800 Plus has eight and two connectors respectively, and AS5404T has four and four.
Double parity alters the capacity ratio
Using equal 12 TB drives and RAID 6, four bays give a nominal 24 TB and eight bays give 72 TB.
How we worked this out
RAID 6 capacity for full arrays of equal 12 TB drives is (4 minus 2) times 12 TB on AS5404T and (8 minus 2) times 12 TB on DXP8800 Plus. System space and formatting are left out.
A 10GbE workstation needs a compatible path from end to end
DXP8800 Plus is the direct hardware match thanks to native 10GbE, though the advertised port rate is only a ceiling.
How we worked this out
The threshold that matters is one native 10GbE port for a workstation path that is already compatible. DXP8800 Plus meets it, whereas the native connectors on AS5404T are 2.5GbE.
Option A
ASUSTOR, AS5404T
ASUSTOR Nimbustor 4 Gen2
A 4-bay chassis whose fastest documented network path is 2.5 Gbps.
- Best for
- Have four internal NVMe sockets next to four SATA bays
Facts we checked
- SATA bays: 4
- NVMe slots in M.2: 4
- Network ports built in: Two 2.5GbE
- RAM, installed and maximum: 4 GB installed and 16 GB maximum
Option B
UGREEN, DXP8800 Plus
UGREEN NASync DXP8800 Plus
One chassis holds eight SATA bays and two NVMe sockets, with dual native 10GbE, for a larger drive plan.
- Best for
- Fit as many as eight SATA drives in one enclosure

Spec by spec
Where they really differ
| Spec | ASUSTOR Nimbustor 4 Gen2 | UGREEN NASync DXP8800 Plus | In practice |
|---|---|---|---|
| SATA bays | 4 | 8 | Only the larger base enclosure has room for an eight-drive archive. |
| M.2 NVMe slots | 4 | 2 | Twice as many onboard NVMe sockets are on the smaller SATA chassis. |
| Native network ports | Two 2.5GbE | Two 10GbE | The link ceiling is faster on UGREEN, depending on the rest of the network. |
| Installed and maximum RAM | 4 GB installed, 16 GB maximum | 8 GB installed, 64 GB maximum | The larger supported memory envelope is what a workload above 16 GB requires. |
| Equal 12 TB disks in full SATA RAID 6 | 24 TB nominal before overhead | 72 TB nominal before overhead | After double parity, four and eight drives leave two and six data-drive equivalents respectively. |
Trade-offs
What each pick costs you
With ASUSTOR Nimbustor 4 Gen2
- Per port, native Ethernet is capped at 2.5GbE
With UGREEN NASync DXP8800 Plus
- Buying and powering more drives comes with more drive bays
Change of plan
When the answer changes
A minimum of six internal SATA drives is required
Go with UGREEN NASync DXP8800 Plus. Eight base-enclosure bays are on DXP8800 Plus.
Four onboard NVMe sockets are required
Go with ASUSTOR Nimbustor 4 Gen2. That socket count is met by AS5404T.
Eight SATA drives and four onboard NVMe drives are both needed by the design
Neither model fits. No base enclosure has both counts.
Decision guide
How to decide
Eight hard drives and four NVMe drives point different ways
Before choosing, write the drive layout out as physical devices. Eight existing SATA disks point to the DXP8800 Plus, and four onboard NVMe drives point to the AS5404T. If the plan needs both counts in one base chassis, neither meets that exact connector requirement.
Double parity alters the capacity ratio
In either full array, RAID 6 reserves two drive equivalents. The arithmetic is (4 minus 2) times 12 TB against (8 minus 2) times 12 TB. That threefold usable-capacity ratio comes before system space, formatting and metadata, and it neither measures rebuild time nor replaces a backup.
A 10GbE workstation needs a compatible path from end to end
Before putting any value on 10GbE, check the workstation adapter, switch and cable path. Either NAS stays constrained by a Gigabit switch on that path. Storage performance and the workload can also limit transfers, and two ports do not guarantee one 20GbE session.
What this page can’t tell you
- Capacity examples assume equal nominal decimal drive capacities
