The catch
Synology DiskStation DS1525+
Hardware media transcoding is a weak point.
Side by side
Synology DiskStation DS1525+ vs UGREEN NASync DXP4800 Plus Compared: For a network that is ready, five internal disks or included 10GbE
Quick verdict
Five internal disks, ECC memory and DSM make the DS1525+ the choice. An included 10GbE port and Intel media hardware, when needed right away, point to the DXP4800 Plus.
Before you buy
Why, and what it costs you
Protected capacity when all drives are 12TB
In this example, Synology DiskStation DS1525+ gives 48TB before formatting and UGREEN NASync DXP4800 Plus gives 36TB. The gap is 12TB before filesystem overhead.
Where this comes from
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
The catch
UGREEN NASync DXP4800 Plus
UGOS Pro's app catalog is newer than Synology DSM's.

What this page compares
Which of DS1525+ and DXP4800 Plus fits depends on protected storage, included networking and the exact SSD or application layout you need.
Each solves a different limit, a fifth drive bay or a built-in 10GbE port.
Which one fits
Pick the situations that sound like you
Protected archive built from 12 TB disks filling every internal SATA bay
This example uses RAID 1 for two disks and RAID 5 for three or more. Synology DiskStation DS1525+ comes to 48TB and UGREEN NASync DXP4800 Plus to 36TB before formatting. The gap is 12TB before filesystem overhead.

Multiple local services dividing up the supplied RAM
Synology DiskStation DS1525+ comes with 8 GB RAM and supports 32 GB, and UGREEN NASync DXP4800 Plus comes with 8 GB and supports 64 GB. Hold the stated application memory requirement up against the supplied configuration before budgeting for an upgrade. RAM capacity by itself says nothing certain about application speed.

Equal 12 TB disks in RAID 6 that still leave 36 TB before formatting
Using 12TB disks, RAID 6 across five bays leaves 36TB on the DS1525+, against 24TB on the four-bay DXP4800 Plus. Under the same two-drive protection rule, that is a 12TB capacity advantage.

In practice
Differences you will notice
Protected capacity when all drives are 12TB
In this example, Synology DiskStation DS1525+ gives 48TB before formatting and UGREEN NASync DXP4800 Plus gives 36TB. The gap is 12TB before filesystem overhead.
How we worked this out
Suppose each SATA bay holds a supported 12TB disk. A two-bay RAID 1 gives the usable capacity of one disk. With three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. The layout is only an illustration. It is not storage that comes included, and it is not a backup.
100GB moved at the speed ceiling of the included port
The lowest possible time at line rate is 320 seconds for Synology DiskStation DS1525+ and 80 seconds for UGREEN NASync DXP4800 Plus. Real copies take longer. A 1GbE client pushes the lower bound to 800 seconds for both.
How we worked this out
Start with decimal 100GB × 8 = 800 gigabits. Then divide 800 by the fastest included port rate, 2.5Gbps or 10Gbps. Protocol overhead is left out of this lower-bound calculation alone, and so are optional adapters and aggregated ports.
RAID 6 takes a smaller share of capacity with a fifth bay
Using 12TB disks, RAID 6 across five bays leaves 36TB on the DS1525+, against 24TB on the four-bay DXP4800 Plus. Under the same two-drive protection rule, that is a 12TB capacity advantage.
How we worked this out
Usable TB for RAID 6 = (N minus 2) × 12. That gives (5 minus 2) × 12 = 36TB and (4 minus 2) × 12 = 24TB. Equal compatible drives, before formatting.

Spec by spec
Where they really differ
| Spec | Synology DiskStation DS1525+ | UGREEN NASync DXP4800 Plus | In practice |
|---|---|---|---|
| SATA drive bays | 5 | 4 | It alters which disk layouts the main enclosure can hold. |
| Fastest included Ethernet port | 2.5GbE | 10GbE | This port rate only helps a transfer if the client, switch and storage keep up. |
| Supported RAM ceiling | 32GB | 64GB | The manufacturer-supported upgrade ceiling for concurrent services is set by this. |
| Processor | AMD Ryzen V1500B | Intel Pentium Gold 8505 | The platform determines the media engines, the application architecture and the concurrency. |
| Software and expansion route | DSM with ECC memory | UGOS Pro | Pick the applications and supported add-ons the job calls for. |
| SATA bays with supported expansion | 15 | 4 | Compatible hardware bought separately, plus a supported pool layout, is what expansion takes. |
Trade-offs
What each pick costs you
With Synology DiskStation DS1525+
- You need extra hardware to get 10GbE or additional bays.
With UGREEN NASync DXP4800 Plus
- Four SATA bays is the limit for this chassis.
Change of plan
When the answer changes
Five internal bays and DSM are required
Go with Synology DiskStation DS1525+. Five internal SATA bays and DSM come with DS1525+. Using equal 12 TB disks, five-drive RAID 6 gives 36 TB before formatting, where the four-bay UGREEN gives 24 TB.
Included 10GbE and Intel media hardware are required
Go with UGREEN NASync DXP4800 Plus. An Intel Pentium Gold 8505 and 10 GbE are included with DXP4800 Plus. DS1525+ ships with 2.5 GbE, so 10 GbE means buying its supported adapter separately.
Decision guide
How to decide
First, pin down the storage layout you need
Five internal disks, ECC memory and DSM make the DS1525+ the choice. An included 10GbE port and Intel media hardware, when needed right away, point to the DXP4800 Plus.
Count what the drive budget allows
Dual 2.5GbE ports come on the DS1525+. Its optional 10GbE capability needs a compatible adapter bought separately, which is why the stock comparison uses 2.5GbE.
Look at the client and apps you will really use
With five 12TB drives in RAID 6 you have 36TB before formatting, and four of the same drives leave 24TB. The extra bay therefore matters for a large archive that needs two-drive fault tolerance.
What this page can’t tell you
- Capacity examples assume equal 12TB drives, counted before formatting, snapshots and filesystem overhead.
- Treat Ethernet calculations as lower bounds, since disk performance, network protocol and other traffic add time.
- Neither application speed nor a VM count follows from memory capacity alone.
