The catch
Synology DiskStation DS1825+
Stock network links run at 2.5GbE.
Side by side
Synology DS1825+ vs UGREEN DXP6800 Pro: Either eight internal HDDs, or six along with native dual 10GbE
Quick verdict
If you need eight internal SATA positions and DSM, the DS1825+ is the one. The DXP6800 Pro suits you better when six bays are plenty and what you value is native dual 10GbE or a supported memory upgrade past 32 GB. Synology’s extra drive positions don’t come with faster Ethernet or a higher RAM ceiling in the package as supplied.
Before you buy
Why, and what it costs you
Six drives at the start leave different room to grow
Six drives fill every SATA bay of DXP6800 Pro and leave two positions empty in DS1825+.
Where this comes from
Two spare physical bays are left by eight minus six, and none by six minus six.
The catch
UGREEN NASync DXP6800 Pro
A six-drive installation fills out every SATA bay.
Synology DiskStation DS1825+
- Why pick it
- Plan on eight internal SATA positions
- Pair DSM with documented ECC memory
- The catch
- Stock network links run at 2.5GbE.
UGREEN NASync DXP6800 Pro
- Why pick it
- Pair native dual 10GbE with an archive of six drives
- Upgrade to a compatible 64 GB of memory
- The catch
- A six-drive installation fills out every SATA bay.

In practice
Differences you will notice
Six drives at the start leave different room to grow
Six drives fill every SATA bay of DXP6800 Pro and leave two positions empty in DS1825+.
How we worked this out
Two spare physical bays are left by eight minus six, and none by six minus six.
10GbE that is ready now favors the smaller chassis
Two 10GbE sockets come with DXP6800 Pro, while DS1825+ needs a compatible add-in card for that link rate.
How we worked this out
Native port rates differ at 10 versus 2.5GbE. Actual transfers also depend on the drives and the network path.
A 64 GB plan points to the six-bay model
Up to 64 GB is supported by DXP6800 Pro. DS1825+ publishes 32 GB despite having more HDD bays.
How we worked this out
64 GB is double the Synology supported ceiling. Both packages start with 8 GB.
Option A
Synology, DS1825+
Synology DiskStation DS1825+
ECC memory and eight SATA bays, plus a supported PCIe route to 10GbE or 25GbE networking.
- Best for
- Plan on eight internal SATA positions
Facts we checked
- SATA bays inside: 8
- Sockets for NVMe: 2
- Built-in Ethernet: Two 2.5GbE ports
- Route for a network card: A compatible 10GbE or 25GbE PCIe card
Option B
UGREEN, DXP6800 Pro
UGREEN NASync DXP6800 Pro
It has two native 10GbE ports, six SATA bays, two NVMe sockets and a supported memory ceiling of 64 GB.
- Best for
- Pair native dual 10GbE with an archive of six drives
Facts we checked
- SATA bays inside: 6
- Sockets for NVMe: 2
- Built-in Ethernet: Two 10GbE ports
- Route for a network card: A PCIe x4 slot, with dual 10GbE already built in
Spec by spec
Where they really differ
| Spec | Synology DiskStation DS1825+ | UGREEN NASync DXP6800 Pro | In practice |
|---|---|---|---|
| Internal SATA bays | 8 | 6 | Spare positions can be kept after the initial build with the larger count. |
| NVMe sockets | 2 | 2 | The onboard M.2 count is the same on both. |
| Native Ethernet | Two 2.5GbE ports | Two 10GbE ports | The higher rated link comes with the six-bay model and needs no card. |
| Supported network-card path | Compatible 10GbE or 25GbE PCIe card | PCIe x4 slot, dual 10GbE already built in | Even with a physical slot, card and software compatibility has to be verified. |
| Supplied and maximum RAM | 8 GB ECC, up to 32 GB | 8 GB DDR5, up to 64 GB | The lower supported RAM ceiling belongs to the platform with more drive bays. |
| Stock operating system | DSM | UGOS Pro | On the selected platform, the app and storage-pool plan has to work. |
Trade-offs
What each pick costs you
With Synology DiskStation DS1825+
- Supported RAM is capped at 32 GB.
With UGREEN NASync DXP6800 Pro
- Switching to UGOS means checking every critical application.
Change of plan
When the answer changes
Both eight internal SATA positions and DSM are essential
Go with Synology DiskStation DS1825+. That storage and software plan suits DS1825+.
Six bays do the job, and native 10GbE or 64 GB RAM is what counts
Go with UGREEN NASync DXP6800 Pro. The relevant published hardware comes with DXP6800 Pro.
In this pair, I want eight SATA bays together with 64 GB of supported RAM
Neither model fits. Both requirements are not combined in either compared configuration.
Decision guide
How to decide
Pick the DXP6800 Pro if six bays cover you and you would rather have built-in dual 10GbE or a supported memory upgrade beyond 32 GB. Pick the DS1825+ if the requirements are eight internal SATA positions and DSM. In the supplied package, having more Synology drive positions gives you neither faster Ethernet nor a higher RAM ceiling.
Six drives at the start leave different room to grow
The DS1825+ is the choice if your plan keeps internal positions open for two more SATA drives. If you will stay at six drives, those extra positions may not give you much. Two NVMe sockets come with both products anyway. Before you count on the spare SATA bays for a painless upgrade later, check the operating system you have chosen, the RAID layout and the migration procedure.
10GbE that is ready now favors the smaller chassis
If your workstation already has a suitable 10GbE adapter, the UGREEN comes with the matching NAS interface in the box. Add a network card to the cost when you price out the Synology. The DS1825+ can take a documented 25GbE upgrade, which is relevant to a different network plan. Neither product comes with a measured count of editing streams.
A 64 GB plan points to the six-bay model
If a workload verified to run on UGOS needs 64 GB, the six-bay model can reach that capacity once you buy the memory. Should the application require DSM, though, the bigger memory figure doesn’t change that software requirement. Synology documents system-level ECC memory and UGREEN lists DDR5 on-die correction. These are two different hardware traits and not the outcome of a matched reliability test.
What this page can’t tell you
- Workload, editing, Plex, reliability and noise were never compared in matched tests. More bays do not show faster compute or networking.
