Reliable network speed tests and smb speeds
Got this on prime day for about $20 USD. For the price and quality it was definitely worth! Works perfectly and as you would expect. No driver installations or dropped connections so far, just plug and play. Sleek design, gets a little warm (which is expected) but not hot at all.
Tested on compatible internal network speeds which showed to be reliable and fast
Hardware tested on:
- base m4 mac mini connected via usb c ugreen 2.5g adapter
- over cat7 ethernet cable (overkill but cat6/cat5e under 100meters/328ft should be enough)
- 2.5g ethernet switch
- 2.5g port on nas
iperf3 tests:
- iperf3 tests from base m4 mac mini to another 2.5g device on a 2.5g switch
- shows average bitrates of ~2.35 Gbits/sec
smb tests from a usb3 connected to base m4 mac mini:
- only took ~2mins to transfer 31.31 GB for 11 files in varying sizes
- which on average came out to around a transfer rate of 2.087gbps
- which is about 260.88 Megabytes per second
- i'd imagine this would even be slightly faster for files directly on the mac but wanted to test with a real scenario
- probably closer 290-300 Megabytes per second for files stored on the device rather than usb3
have not had a need to test this on mobile yet but iphones with the 10g usbc (and probably just usbc in general) should be fine
i'm sure if you're looking into buying one of these you already know all this but some things to keep in mind. your mileage may vary based on your cable length and runs/environment surrounding your network/cables for any electromagnetic interference. but generally as long as you have 2.5gb compatible ports and cabling and you should be good to go!

Solid USB-C Upgrade for 2.5GbE - Good Value and Performance - Good for Mac Users
I’ve been using this Ugreen adapter for a 6 months now and it’s become one of my go-to accessories. If you have a device like the M1 MacBook Pro or Mac Mini that’s limited to 1Gb Ethernet, this adapter is a great way to unlock faster speeds, especially if you’re upgrading your home or office network to 2.5GbE. I have everything connected to a 10Gb switch after I upgraded my Synology NAS and needed a way to improve access to it for storage.
Setup was truly plug and play, just connect the Ethernet cable to one end, plug the USB-C into your device, and you’re good to go. I noticed an immediate improvement in transfer speeds when moving large files to my NAS. This is perfect for anyone working with media or large data sets where Wi-Fi just doesn’t cut it. I was initially capped at 200MB/s. It more than doubled when I used the adapter to 200MB/s
At around $20, it’s excellent value when compared to higher-end adapters that cost much more but often deliver the same result. It’s compact, feels well made, and I’ve had zero issues with performance or stability. It does get slightly warm during long transfers, but I haven’t seen any drop in connection quality or speed.
If you’re trying to squeeze more speed out of your Mac Mini, laptop, or even a docked tablet, this is a solid upgrade. I keep mine on the desk and switch it between devices as needed. Highly recommended for anyone moving to a 2.5Gb network or needing faster wired performance.

MR. SULU… PREPARE FOR WARP SPEED. ENGAGE.
Rocket fast. Sleek, smooth design. Have another adapter from different company, which tends to fail when utilizing more than 1.5 GB. It just decides to downshift the first gear.
This adapter does not.
Speeds are scary.
SpeedTest results are fun, watching the gauge being download teat and swing radically to the right. Pinned.
Speeds coming in at 2,327 mb/s uploads at 2,150 mb/s (depending on time of day.
Great for streaming content from laptop 4K, Dolby Vision Dolby Atmos, no problems… smooth no hiccups

Great speed, connection sometimes blocked but there is a solution.
I wanted to take advantage of my 3gb fiber connection, and the best way was to connect my Mac M1 via Ethernet. This looked like a good solution. It started pretty good. I could almost max out my 2.5gb port on my switch. Then a strange thing started happening.
At odd, but consistent, intervals, my connection would stop and say it was 'blocked'. If I waited, it would come back to active. If I switched Thunderbolt ports, it would come back instantly. Annoying.
After a couple of days trying different ports, cables, DHCP vs static IP, and WiFi working flawlessly, I figured it was something in the Mac. Many Google searches directed me to the Thunderbolt Bridge. Apparently, this feature is to directly connect two Macs together IP for a high-speed connection. But it has been known to cause my issue.
I removed the Thunderbolt Bridge service (I can add it back later if needed), rebooted, and have been working great for over a day now. Hopefully, this might help someone in the future.

Installation instructions are flaky, but unit works well when installed
I bought this because I wanted a simple way to upgrade an old tower PC to support 2.5gig Ethernet and I thought it would be easy. Well, it wasn't. The user manual that came with the unit had instructions to download drivers. After a lot of work, I found them, but the files were empty. Then I noticed that a new USB device, a CD rom drive, had been added to my PC.
I unplugged the adapter and went into device manager and deleted the device and its files. When I plugged the unit back in, it was recognized as a NIC and started working. The unit runs at 2.5gig and seems to work well but I keep wondering if, the next time I have to unplug it, it will go back to looking like a CD drive. Oh, I did not need drivers. The unit is installed automatically under Windows 10.
