Head-to-head
Synology DiskStation DS1525+ vs UGREEN NASync DXP4800 Plus: Five internal disks or included 10GbE for a ready network
The short answer
Choose the DS1525+ for five internal disks, ECC memory and DSM. Choose the DXP4800 Plus when an included 10GbE port and Intel media hardware are immediate requirements.
Before you choose
The reasoning and the trade-offs
Protected capacity with equal 12TB drives
Synology DiskStation DS1525+ gives 48TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. The difference is 12TB before filesystem overhead.
What this is based on
Assume every SATA bay contains a supported 12TB disk. Two-bay RAID 1 uses one disk of usable capacity. For three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. This is an illustrative layout, not included storage or a backup.
Main trade-off
UGREEN NASync DXP4800 Plus
UGOS Pro has a younger app catalog than Synology DSM.

A fifth drive bay and a built-in 10GbE port solve different limits.
Winner by situation
Start with what you need it to do
A protected archive using 12 TB disks in every internal SATA bay
Using RAID 1 for two disks or RAID 5 for three or more disks, Synology DiskStation DS1525+ gives 48TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. The difference is 12TB before filesystem overhead.

Several local services sharing the supplied RAM
Synology DiskStation DS1525+ supplies 8 GB RAM and supports 32 GB. UGREEN NASync DXP4800 Plus supplies 8 GB and supports 64 GB. Compare the stated application memory requirement with the supplied configuration before budgeting for an upgrade. RAM capacity alone does not establish application speed.

Keep 36 TB before formatting with equal 12 TB disks and RAID 6
With 12TB disks, five-bay RAID 6 leaves 36TB on the DS1525+ versus 24TB on the four-bay DXP4800 Plus. This is a 12TB capacity advantage under the same two-drive protection rule.

What matters in practice
The differences that matter
Protected capacity with equal 12TB drives
Synology DiskStation DS1525+ gives 48TB and UGREEN NASync DXP4800 Plus gives 36TB before formatting in this example. The difference is 12TB before filesystem overhead.
How we reached this conclusion
Assume every SATA bay contains a supported 12TB disk. Two-bay RAID 1 uses one disk of usable capacity. For three or more drives, RAID 5 usable TB = (drive count minus 1) × 12. This is an illustrative layout, not included storage or a backup.
100GB transfer at the included port ceiling
The line-rate lower bound is 320 seconds for Synology DiskStation DS1525+ and 80 seconds for UGREEN NASync DXP4800 Plus. Real copies take longer. A 1GbE client makes the lower bound 800 seconds for both.
How we reached this conclusion
Decimal 100GB × 8 = 800 gigabits. Divide 800 by the fastest included port rate, 2.5Gbps or 10Gbps. Ignore protocol overhead only for this lower-bound calculation. Optional adapters and aggregated ports are excluded.
A fifth bay makes RAID 6 less capacity-intensive
With 12TB disks, five-bay RAID 6 leaves 36TB on the DS1525+ versus 24TB on the four-bay DXP4800 Plus. This is a 12TB capacity advantage under the same two-drive protection rule.
How we reached this conclusion
RAID 6 usable TB = (N minus 2) × 12. (5 minus 2) × 12 = 36TB. (4 minus 2) × 12 = 24TB. Equal compatible drives, before formatting.

Meaningful differences
What changes the fit
| What changes | Synology DiskStation DS1525+ | UGREEN NASync DXP4800 Plus | Why it matters |
|---|---|---|---|
| SATA drive bays | 5 | 4 | This changes the disk layouts possible inside the main enclosure. |
| Fastest included Ethernet port | 2.5GbE | 10GbE | The client, switch and storage must keep up before this port rate helps a transfer. |
| Supported RAM ceiling | 32GB | 64GB | This sets the manufacturer-supported upgrade ceiling for concurrent services. |
| Processor | AMD Ryzen V1500B | Intel Pentium Gold 8505 | Media engines, application architecture and concurrency depend on this platform. |
| Software and expansion route | DSM with ECC memory | UGOS Pro | Choose the applications and supported add-ons required for the job. |
| SATA bays with supported expansion | 15 | 4 | Expansion requires separately purchased compatible hardware and a supported pool layout. |
What you give up
Every choice has a cost
If you choose Synology DiskStation DS1525+
- 10GbE and extra bays require additional hardware.
If you choose UGREEN NASync DXP4800 Plus
- The chassis cannot expand past four SATA bays.
Recommendation switch
The decision flips if...
You need five internal bays and DSM
Choose Synology DiskStation DS1525+. DS1525+ has five internal SATA bays and DSM. With equal 12 TB disks, five-drive RAID 6 gives 36 TB before formatting compared with 24 TB in the four-bay UGREEN.
You need included 10GbE and Intel media hardware
Choose UGREEN NASync DXP4800 Plus. DXP4800 Plus includes 10 GbE and an Intel Pentium Gold 8505. DS1525+ ships with 2.5 GbE and needs its separately purchased supported adapter for 10 GbE.
What matters in practice
How to make the call
Start with the required storage layout
Choose the DS1525+ for five internal disks, ECC memory and DSM. Choose the DXP4800 Plus when an included 10GbE port and Intel media hardware are immediate requirements.
Work through the drive budget
The DS1525+ ships with dual 2.5GbE ports. Its optional 10GbE capability requires a separately purchased compatible adapter, so the stock comparison uses 2.5GbE.
Check the actual client and application plan
Five 12TB drives in RAID 6 leave 36TB before formatting. Four of the same drives leave 24TB. This makes the extra bay meaningful for a large archive that needs two-drive fault tolerance.
What this comparison cannot tell you
- Capacity examples use equal 12TB drives before formatting, snapshots and filesystem overhead.
- Ethernet calculations are lower bounds. Disk performance, network protocol and other traffic add time.
- Memory capacity does not certify application speed or a VM count.
