A USB-C cable can be the quickest way to move a project folder, but it is not automatically the best path for every large file transfer. Direct USB-C work depends on compatible ports, cable capability and the destination drive. A network route can be slower on paper yet much easier when several people need the same files. Choose by measuring the complete route rather than trusting a label on one connector.

Quick Answer

USB-C 10Gbps has the higher headline rate, but an end-to-end 2.5GbE network can be more convenient for shared transfers. Actual speed follows the slowest drive, port, cable and destination, so benchmark the same large file on both paths. At R8,499, the diskless UGREEN NASync DXP2800 provides a 2.5GbE LAN port and USB-C 10Gbps, but compatible SSD or HDD storage must be added before either route can carry data.

🔌 Compare the routes before comparing numbers

USB-C 10Gbps describes a connection ceiling, not a guarantee that a copy will finish at that rate. A laptop might have a slower port, a cable may support charging without delivering the expected data mode, or an attached drive may be unable to read and write quickly enough. Start by identifying both ends of the cable and the storage on each end. Then copy one large test file, such as a video export, rather than a folder made up of thousands of tiny files.

Network transfers involve more parts. The NAS port, switch, router, computer adapter and Ethernet cable all negotiate a speed. A 2.5GbE NAS linked to a Gigabit switch will operate at the lower link rate. That does not make the network unusable; it simply means the result should be interpreted correctly. The wired networking range is the place to check the equipment that joins those links.

For a temporary handover to one attached device, a direct route can be practical. For a shared library used by several computers, the network route avoids repeatedly connecting a cable and keeps files in one place. The job, not the headline figure, should decide the first test.

🧪 Benchmark the same workload fairly

Create a test folder containing one large file and a separate folder with many smaller items. Time each transfer in the same direction, then reverse the direction. Reading from a fast source and writing to a slower target can produce a very different result from the return copy. Note the result, the file size, the connection method and whether other users were active.

Do not run a speed test while a backup, photo index or media task is competing for the same drives. Wait for the system to settle, or repeat the test at a quiet time. If one attempt is much slower than the next, look for another task rather than assuming the cable or NAS is faulty.

The UGREEN NASync DXP2800 pairs 8GB DDR5 with an Intel 12th Gen N-Series quad-core processor. Those resources assist its storage workload, yet an installed drive, congested Ethernet segment or slow client can still be the limiting layer. That is why a repeatable benchmark is more useful than one optimistic transfer window.

🗃️ Let the storage decide what it can sustain

The medium holding the files has to keep up with the connection. A large sequential copy can behave well while a small-file backup feels slower because every file needs extra directory and metadata work. A nearly full drive can also behave differently from an empty one. Check free capacity, file type and whether the source or destination is doing another job before buying new networking equipment.

The DXP2800 is sold without SSDs or HDDs. That makes the diskless NAS storage category relevant before a speed comparison: the enclosure is only part of the transfer path. Choose installed media for capacity and workload, then test the completed system instead of assuming an empty product specification predicts a finished setup.

Cable selection still matters for direct operation. Avoid treating any USB-C lead as interchangeable. Check its stated data capability, inspect it for damage, connect it firmly and test with a known large file. The cable solutions category gives a useful starting point when replacing a questionable lead.

👥 Decide whether sharing changes the answer

A direct USB-C connection is private to the device at the other end. That can be ideal for a one-time ingest or a local transfer. It becomes less convenient when a household, team or editing group needs current access to the same material. A network share can leave the file in one managed location, with named access and a backup process around it.

Think about the next month rather than only today's copy. If the same archive will be opened from different rooms or computers, test the network path where those people work. If one person regularly takes a project away, establish a separate export or synchronisation routine. A transfer method is successful when it fits the handover process as well as the stopwatch result.

📋 Choose the path from the handover pattern

A direct USB-C copy makes sense when one editor needs to ingest or return a large project and the destination is beside the NAS. It avoids asking every device in the room to support the same network speed. Before relying on it, test the actual cable with a file that is large enough to run for several minutes, then repeat the copy in the reverse direction. A result that collapses only in one direction usually points to the source or destination storage rather than the connector name.

The network path wins when the same material must remain available after the first copy. Put the NAS, switch and regular client on Ethernet, check that each link negotiates at the intended rate, then copy the same test file from two different computers one at a time. If the second machine only reaches Gigabit, upgrading the NAS side alone will not make that client faster. Keep the measured results with the project so the team knows which route is for fast local ingest and which is for shared access.

Frequently Asked Questions

Is USB-C 10Gbps always faster than 2.5GbE?

No. USB-C has the higher advertised link rate, but real speed can be limited by the ports, cable and attached drives. A well-built 2.5GbE path may be more useful for shared storage even when its headline rate is lower.

Why do small files copy more slowly than one video file?

Thousands of small files create extra file-system and directory work. One large file usually tests sustained reading and writing more directly.

Can the DXP2800 use both connection types?

It has a 2.5GbE LAN port and USB-C 10Gbps connectivity. The suitable route depends on the devices, cables, installed storage and the workflow being tested.

What should I record during a transfer test?

Write down file size, direction, connection method, linked speed and other activity on the NAS. Those details make a later comparison meaningful.
