In our round-up, we compare three Marvell/ Aquantia AQC111U adapters that convert USB 3.0/ 3.1 to 5GbE. Although these three units from StarTech (USG5GA30), Sabrent (NT-SS5G), and TRENDnet (TUC-ET5G) all use the same controller chip, we see differences in performance, stability, physical specs, and pricing. In this video, we discuss what we found when comparing the three units.

The moment I saw USB 3.1 Gen 1 on the chart the problem was obvious. The decision to have this Gen 1 / Gen 2 stupidity attached to USB 3.1 is a source of endless annoyance.
Yes, I still dont get why didnt they just go with 3.0 for 5gig, 3.1 for 10gig, and 3.2 for that gen 2x2 nonsense.
@@kojetono5853 There are some actual differences, mostly in the power management modes that came with the Type C connector, so you could have a laptop that did everything including power through the USB ports. But most of it is more esoterica than anything else for people who just want to know if higher speed is supported. Personally, I think it would have been better if the spec treated the 10Gb/s mode as a requirement for certification as USB 3.1. It would have saved consumers a lot of confusion and probably accelerated adoption of the 10Gb/s and later 20Gb/s (requiring Type C) modes.
It is always a joy listening to Patrick, no matter what he is reviewing or saying.
Patrick's boots-on-the-ground experience is VAST!
The guy oozes enthusiasm and passion.
Thanks for the comparison, I'm looking at getting some of these to speed up my laptop testing, pretty annoying none of them are using USB 3.1 Gen 2 as that's 10gbps, at least then in theory these 5gbe models would get full speed. Like you say though, I'll still take the 3x+ boost over gigabit.
Isn't USB half-duplex though? It would still prevent it from running at full speed both ways.
Engineers: Boss we did it 5gbps
QA Team: we have a small issue, its not consistent
Boss: Don't worry about it, most people wont even notice.

After watching your written reviews. I was really hoping you'd a youtube video for all these 5gbe adapters. Thank you Patrick you are amazing. And hope 2021! Will bring even more video reviews. !! Happy new Year!!
11:55 and that's why it don't read ZDNet articles...
Thank you for the comprehensive testing and thorough review of these 5Gb Ethernet adapters. Stay well!
Great video! With USB3.1gen1 you have 20% overhead just from the bit encoding scheme, which brings the max data throughput down to 4Gb/s, before any protocol level overheads. Gen2 has a 5% or so encoding overhead, and supports store and forward in the hub when talking to slower speed devices, so you should be able to jam a lot of high performance devices (even previous gen USB3) on a single root controller. That’s something I have been playing with for 4k video capture cards and external drive arrays as a flex. Might be a fun video or review to do on mini micro systems.
Glad you mentioned these "frame" sizes:
8b/10b = "legacy frame" e.g. 5G / 10 = 500 MB/sec
128b/132b = "jumbo frame" e.g. 5G / 8.250 = 606 MB/sec (to compare)
128b/132b = "jumbo frame" e.g. 10G / 8.250 = 1,212 MB/sec
Thus,
10/8 = 25% encoding overhead
132 / 128 = 3.125% encoding overhead (USB)
130 / 128 = 1.563% encoding overhead (PCIe 3.0)
Happy new Year STH! Love your work and detailed reviews! Please try to review QNAP one
Your channel is a goldmine for info, thanks for all the videos sir !
I use the Sabrent unit for work. No issues beyond not getting the full speed, and heats up after significant use over a long period. Our use case is for ingestion of engineering machines data. For backup or replication. We have also used it when needing to download large model libraries to engineer work stations.
wow, I mean wow - i love how cavalier some people are about this video. This is a great in depth vid regarding real problems I am facing right now. My current issue - Jabra Panacast conference room camera. They give you a 5 ft cable. I have to get this camera feed to the conference room table and actually work. I would guess 35 - 45 ft (from camera, through raceway in floor, back up poke through, tie into hub mounted under table, then feed to computer on table. Sounds easy right, ha! Try getting the data needed to support video feed at the correct rate at that distance knowing the camera has a USB-C connection. Not easy unless you are ready to drop $2500 on a USB 3.1 over ethernet extender kit. I greatly appreciate your video and the labor you performed on all your testing. That is a lot of work and I am impressed!
Great review. Pros/Cons, the Sabrent units seems the best but my only concern is a cable being pulled might undo the connection as it has more failure points if that happens, would still buy it instead of the others for the cable options. It would be a cool dongle to have when troubleshooting servers in the data center for the far off failure of a NIC and a quick way to get data/config off such a server.
Awesome content. Have a great year Patrick!
Been waiting on this video. Good stuff.
I just bought the 2.5gbe Sabrent adapter, still glad I did. It was about $30.
Even if the $60 Sabrent 5gbe adapter is the best deal of the 5gbe adapters... When compared to the 2.5gbe adapters, it is 2x the cost, and definitely NOT 2x the performance.
If you buy this for say work, then for a person earning just $10/hr would break even on 3 hours of extra I/O bound activity that would have been used for useful work. If you are on a LAN with large files, let's say this happened for just 1 minute a day, then the break even would happen at 9.5 months of regular working days. If you earn $100/hr with the same workload, the break even would happen after 1 month of use.
Wish I knew about the Sabrent adapter sooner. Might have saved maybe $15-20 per adapter over the Qnap 5gig USB3.1 adapters. Wondered about the not-quite 5gig transfer rates. Makes sense about the usb overhead. Very informative review.
Thanks for the review. I had issues, similar to what you reported, with TRENDnet and my MacBook Pro.I got QNAP QNA-UC5G1T instead.
Tell us about it! Is it working well?
when you mentioned backpacking if the concern is potability/mobility detachable cable is a very big plus, that cable can be used for lots of things
I was stretching for why one may spend $102 on the StarTech.
Not sure why you'd need 5Gbps ethernet while backpacking. I've done a couple years backpacking and never had a time I've even needed 1gbps. As far as I'm aware the only real reason for faster ethernet is to connect to a server on a local network. For fast storage on the go, an SSD in a 3.1 case would be far preferable.
I can only imagine someone wanting a lighter version with a fixed cable for something like a tiny mini micro project where they're going to be hanging from the computer all the time, but you might as well use a unit with a longer detachable cable and have it lay on the table/floor underneath
@@morosis82 You could have a laptop to work, with only GBE. At home you have your docking station, but at work, moving in the building you'd have your usb to ethernet dongle to connect at full speed wherever you work...
In my workspace, i work in different places, it would come handy. However, i'd take the metal unit anyway : removable cable means i can use the same cable for multiple stuff, the cable won't bend and kink rendering the device unusable; i would be less worried about the unit being damaged; and anyway, what is the weight difference between those two units?
As for the workspace, another solution would be to settle for less speed (2.5GB), and buy a few, have them located in the sports where you usually work, permanantly, since they are about 20$.
@@morosis82 backpacking here is not like traveling the world with just a backpack but more like needing to move around in different job sites etc.
Cheers for the gen 4 optane info on STH site, very cool.
Thank you bro
I really appreciated the knowledge and understanding 👍
I have the QNAP usb-c 3.2 gen1 version around 3 Gbits/sec as well. It's been pretty reliable so far.
Thanks for the info, I actually would have bought the trendnet model, I have had good luck with their products in the past.
It makes a lot of sense that is a usb limitation, given that 3.5 Gbit equates to a bit over 400MB/s which is the max transfer speed most SSDs over USB 5Gbit reach as well
I wonder if there are any USB 3.1 gen 2 adapters and how these would perform in linux/bsd.
Unfortunately nobody makes a gen2 chip yet...
@@kilrahvp I've recently discovered that even thunderbolt is limited to 10Gb
@@Chris-rm1pn Thunderbolt 3 is limited to 20Gb of actual data speed, and because it's essentially encapsulating PCIe you don't end up with the USB conversion. Thunderbolt 3 10GbE adapters run at (roughly) full speed.
@@ermacstudios Thunderbolt 3 bandwidth is 40 Gbit/s, not 20 Gbit/s (that was Thunderbolt 2)
@@roppongi765 You are correct that the theoretical bandwidth is 40Gb/sec, but because of Intel spec you can only get 22Gb/sec of actual throughput because of protocol overhead and bandwidth that's reserved for the DisplayPort 1.2 channel that runs in parallel.

Please do the third one and add the results in on a card or in notes. It would be interesting to see any data points that you can gather.
Wow what a great review. First time watching this channel and im a fan.

You sly dog 😈
In terms of if the price premium over 2.5 gig adapters is worth it: sometimes you just want to get the fastest networking speed you can on a machine that has no internal expansion or thunderbolt ports, and 3.5 is more than 2.5. On the other hand, if you do have thunderbolt ports, it appears that OWC's 10 gigabit TB3 adapter is down to $149, so that's actually more gigabits per dollar.
Curious if any of those adapters, particularly the Sabrent works well with pfSense. If you could use the built in NIC + an adapter on a micro form factor system that'd be sweet!
Thanks for this interesting test. I hope there will be some USB 3.1 gen 2 or higher options soon with 10gbit USB you should be able to get 5 gbit out of the ethernet side...
Now that was nerdy, nice. Thank you
This was useful. Thank you!
Love sth always great stuff :)
Really well done review, thank you
This (10Gbe Thunderbolt 3 Adapter) gets extremely hot and i wonder if the rubber casing adds to the heating problem - after it gets too hot it stops working until it cools down, also needs to be plugged in via Ethernet to a primary internet connection (not daisy chained switches) drivers can be a bit tricky to install......not meant for extended consistent use. Heatsinks do very little to dissipate the extreme heat.
Awesome video.. Now I have to go check my ASUS 10GB adapter to see if it using the same chipset. EDIT: It has an AQC107.... and I am curious if this is also limited. Time for some testing.
great content.. much appreciated
I bought a Trendnet TUC-ET5G and notice the problem but never took the time to investigate, but after seeing the video I contacted TrendNet and created an RMA for it. Let see when the new unit arrive
I have been using the a pair of the QNAP 5GbE unit on my MicroServer Gen10 Plus and EC200a. It had no problem with either Windows or Proxmox VE, but the QNAP unit will cause Arch Linux to hang on boot if it was plugged in. I have not managed to pinpoint what's going on so I moved one of the QNAP NICs that was for my laptop to my EC200a (to speed up rsync backups between the two servers). Maybe I should grab a pair of the Sabrnet cards because the QNAP cards also use a customized firmware/driver stack, and maybe that's why it was hanging Arch Linux.
I've had bad luck with Realtek 2.5GbE adapters, they constantly drop connections (very severe on Proxmox, better on Arch and Windows), and the Sabrnet one was not available back when I built my MSG10+, and the QNAP one was the best bang for the buck back then.
If there's no extra changes on the trendnet unit, you might be able to manually install the standard Marvel driver and make it work fine. I wonder if it's posible, at least you have an alternative if you already own it or don't have the other models available
Can you review the TB3 10GbE adapters? There are entries from OWC, Sonnet, QNAP, and CalDigit, and I haven't found a comprehensive comparison
I'm glad I haven't bought one of those (I was tempted to buy the QNAP one) and went just with a 2,5Gbe instead.
This is review cranked up way past Beast mode!
Subscribed.
Any 10Gbe usbc-gen 2 adapters that don't cost 500$?
Need more 10gbe ones
I like the detachable cable design of the Sabrent. My understanding is the the design of the USB-C connector puts the parts subject to most wear on the plug rather than the socket as the plug is typically part of a replaceable cable and the socket part of a more costly device?
Very helpful. Thank you!
Great informative video!
I want to ask a question of you as you're better informed than I am. I recently upgraded my home's cable modem from a Netgear C7000 that I've had for years for under 1gbps connection speeds. Now, Comcast Xfinity offers 1200mbps in my area and I wanted to try it out. I now own a Netgear CAX80 which has a single 2.5GbE port. My PC's motherboard is a X570 ASUS Dark Hero which has a Realtek 2.5GbE NIC. I am on the latest firmware and driver on my hardware, but for some odd reason the 2.5 keeps cutting out and auto negotiating down to 1gbps, even when I force it through software to only choose 2.5GbE.
I brought this up to both companies (Xfinity and Netgear) and they're playing the finger pointing game. I am looking for clarity if possible: Purchase an add-on card or USB 2.5GbE or swap to another brand's 2.5GbE modem.
Thank you for your help.
"This is much longer than that." - the sort of review content we need.
Great information. Great effort.
Both Startech and QNAP make 5GbE NICs that install into a PCIe x1 slot. I would like to know how those adapters perform vs. the USB adapters.
Are there are any other reasons besides cost to choose a Realtek-based 2.5Gbps adapter instead?
For instance, what about latency, jitter, stability, driver compatibility (Linux, Freebsd, VMware), switch compatibility, CPU utilization, thermals, power consumption, TCP offloading/queues ?
Would these have ranked higher if they locked them to 2.5gbe? Does the Sabrent have a thermal connection between the chips and the case to help with thermal problems? I ran into this a lot when trying to use a usb-gigabit adapter for pfsense, if I clamped then to a cool rack shelf, they would work longer between drop outs. Gave up on USB adapters for firewalls, but it would be REALLY handy to have a good solid device that didn't drop out for quick or cheap builds.
Based on your review, I bought the Sabrent 5Gb USB to Ethernet adapter. I just got AT&T 2Gb fiber (it's actually 2.5Gb/s fiber) at my house for our Internet connection, and wanted to take full advantage of that speed and bandwidth, so built out a 10Gb environment as a mini-backbone. Attached the AT&T gateway/modem to the 10Gb switch via the built-in 5Gb Ethernet connection on the back, then purchased two Engenius EWS377AP Wi-Fi 6 access points that have 2.5Gb Ethernet POE ports, and they also are attached directly to the 10Gb switch. I connect the Sabrent directly to the 10Gb switch as well.
I'm getting 1.2Gb/s to my PC, via Wi-Fi 6, through the Engenius APs, and 2.3Gb/s through the Sabrent 5Gb adapter, so even though it can't get much more than 3.5Gb/s in your tests, it completely fulfills it's purpose in my system.
Well, if you're limited to a 5 Gbps USB connection, you know immediately that you cannot possibly break 4 Gbps due to the 8b/10b encoding used by 5 Gbps USB. And then you have more protocol overhead on top of that.
USB 3.1 is capable of 10 Gbps with Gen 2, so determining the reviewed devices are Gen1 limiting you to Gbps is a key step. When I was looking manufactures and retailers were obscuring this info.
I would be very interested in seeing a video about USB-eth module in Linux (TCP over USB)
So... how well does the Sabrent work in Linux? I have an Aquantia 5G PCIe card that chokes when I try to upload anything large to my server (confirmed with iperf, it's not just samba or whatever I happen to be using then). It's a commonly reported problem and is probably an inter-frame gap issue but I haven't figured how to fiddle with that, so I'm wondering if these behave differently.
So if you want to build some small SFF pc for backups (like bare debian with nfs/iscsi) what are the base CPUs which would allow to squeze 3,5Gbps from these?
Have you tried enabling jumbo frames(9014) or tweaking the iperf parallel session count? I'm wondering if you can get it closer to 4.5Gbps?
Powerful start, followed by performance drop after device gets warmer?
Hi
With the trendnet adapter have you tried to disable some low power mode in advanced settings?.
Wish the Sabrent had been available when I got my Startech.
To me it comes down to anything with a built in cable is likely to die eventually where the cable goes into the case, whereas a USB-C port probably wont.
Oh and yes getting the 5Gbit adapters is a good thing vs the Realtek, as they stopped supporting new Linux kernels instead telling you to rely on the stock USB Ethernet support which doesn't do Jumbo frames and spams the logs with link/up down messages. I mean it works, but the Realtek driver worked better and just abandoning it leaves a bad taste in the mouth.
I have an 5gbit Aquantia NIC on my x299 Deluxe Prime II. While the performance is fine, at high incoming throughput it crashes. I invested weeks without success (drivers, firmware, cooling, config parameters ...). Got an Intel x550-t2 instead.
I have a QNAP one and I do want to see a review on it. I use it on a Hackintosh and it sometimes drops connection, but I don't know if it's a problem with the Hackintosh USB patch or the adapter itself.
I have a pair of those and performance is excellent, but every time i reboot my nas i have to unplug re-plug it from the nas to make it work again, once it works it is reliable for months or whenever you need to reboot the system
The Realtek 2.5gb dongles also have wide variance in driver quality. Does Aquantia make a 2.5 gig variant?
Do they get hot? How much power do they consume? Did you compile a chart on transfer speeds? I'm thinking what it like transferring 50k small files vs equivalent size few large files, I.e. real world.
Question, if a NAS such as a Synology or QNAP has 4 x 5 Gb USB3.0 ports on the back do each of them get 5Gb or is the 5Gb shared across the 4 ports?
How is that flow control working and what about Linux kernel support? Are there any gen2?
Any new recommendations now that a year has passed? Looking for one for my Surface Pro 8 and M2 Mac Air. Any recommendations? Thank you!
Will you be reviewing any TB3 10G (rj45 or SFP+) units? I'm interested in the Sonnet Solo 10G Thunderbolt 3 to SFP+ 10 GbE adapter
If there is interest in this we can work on 10GbE units as well.
why tb3? i hate tb3, its just a lot of problem, usb is way more user frendly
I am also very interested in 10gbe choices. The thunderbolt ones and also official plug in copper ones. What switch did you test with?
I highly recommend the QNA-T310G1S this is the SFP+ version (not the Rj45 one, that's a very different experience). I have had 3 of them running off 3 of my HP elitedesk minis. They don't need a fan, and only run slightly warm at max load. So far running for over 4 months no issues (all 3 are proxmox)
@@AtomicEnd Are you plugging the QNAP adapter into a USB C port or a Thunderbolt port? A quick look at the specs of the Elite Desk mini shows it has USB C gen 3.2 ports, but might also be able to have an additional Thunderbolt port?
Thanks guys
Any testing done on linux and macs ? ARM, Intel and Apple Silicon drivers ?
Given the choice, would you buy a PCI-e internal 10Gbe NIC or a Thunderbolt 10Gbe?
Is there a chip on any of these adapters from your extensive research that supports usb 3.1 gen 2 for the full 5 Gbps?
If I could get a cheap 5Gbit switch, then I might consider the 5Gbit adapters. For now, I'll stick with 2.5Gbit on my QSW-1105-5T.
The Sabrent packaging/design I much prefer.
I cannot help but notice, that these test where done out of the box, with Windows 10. Which actually, lately, has a notorious 3.5Gbit's cap, even on 10Gbe. Not sure if these can run on Linux out of the box, but that would be one way of getting around this. Another could be to try and disable Interrupt Moderation in the Network Adapters Advanced settings. Just to make sure, Windows isn't the bottleneck.
Somthing you can try: take the Trendnet one apart to reflash its configuration memory to something stock original, for example the configuration from another onein this review, and re-benchmark?
We had talked about it. Given there are less expensive models out there, we felt the expectation should be it works as-is without those extra steps
@@ServeTheHomeVideo The intention of that test is to check whether it is the hardware implement being at the fault, or the driver optimizations. That firmware modification forces the Trendnet NIC to not use their own driver.
I have a pair of the QNAPs, they're basically identical to the Sabrent, although a bit smaller apparently. Metal body, uses standard drivers, USB-C port with 2 (shorter) cables supplied and work fine. Was aware of the limitations but there's just nothing better since there are no Gen2 chips yet and TB3 10Gs are just too huge and expensive.
Did you disable the power saver option on the trend net unit in the nic properties?
Actual physical speed of 5GbE is 4.688 Gbps minus assume 10% encoding and header loss come to about 4.2 Gbps. Furthermore there is USB lantency. The reason for gradual slowing down is because fragmentation, enable jumbo frame on your network adapter and switch would solve this problem.
PLEASE add chapters so we can dispense with the pleasantries and get to the content we're here for.
Awesome video, have you guys tested this with pfsense at all? hoping to add an easy "5gbps" connection to by box since it doesn't have any extra expansion slots.
Great Content. Why not try it on a powered usb hub. It maybe the trendnet unit want more power than usb is capable of.
We did. We even tried higher-power USB 3.2 Gen2 charging capable ports. The same thing happened.
I have another alert for those looking for 10Gig USB thruput All the single lane PCIE cards you find are limited to 5Gig per second speeds. Only the 4 Lane PCIE cards can give full 10Gig/sec thruput. I will be looking at the 2.5 Gig/second units. My use case is for pure server to storage point to point links, bypassing a gigabit switched LAN with many 100Mbit devices on it.
Can you recommend any 10GBase-T NICs?
Sonnet also makes the SOLO5G-USB3, based upon the Marvell AQC11U, with two detachable cables. They advertise a max transfer rate of 400 MB/s. Two year warranty and lifetime tech support. It'd be good to include this one when you also look at the QNAP one.
www.sonnettech.com/product/solo5g/techspecs.html#techspecs
I have an ITX build and this may be the only way for me to gain higher network speed.
Can you please add in the review for qnap too. Thanks
Ordered two QNAP NICs so we could repeat the process for them as well. These will likely just be on the STH main site in a review not on YT.
When you saw the Trendnet unit 'drop' were you still able to ping between units?
We've had reliability issues with USB3 to 5GBE adapters (we use the QNAP UC5G1T on laptops to allow for high rate data export from servers) where after some time the unit simply stops receiving data (well, effective receive rate drops to < 100k/s) but the upload is not affected. You could still ping between systems.
I initially suspected the issue was with the Netgear switch, but with further testing I believe the issue is due to the QNAP USB 5GBE.
More info and full use case here: community.netgear.com/t5/Smart-Plus-and-Smart-Pro-Managed/XS512EM-with-Aquantia-10Gbe-stops-uploads/td-p/1925484
No. Link was down when the units dropped.
I tried to use the QNAP 5gbe USB adaptor with my QNAP TS-431p NAS and it kept dropping the connection when doing intense operations. This was at 2.5GBE speed with a TP-Link 5-port 2.5gbe switch. I ended up going back to standard gigabit for the NAS since that doesn't require any configuration and is reliable. It's a shame since the QNAP usb adaptor was really expensive.
I have the same NAS and the same behavior with my QNAP 2.5gb/5gb adapter when used on the NAS. Not happy with QNAP right now, support is terrible
Happy to provide data on qnap 5gbe adapters through a 10gbe switch?
I could not believe your test results with the Sabrent NT-SS5G. Clearly 3.1 Gen 1 is the problem, but this can be fixed to a certain extent. I have a hybrid 2.5/10 Gbs wired network of TP Link ER-707 M2 router and two NICGIGA 8x10Gbs switches, 4 x570 AMD Ryzen 9 5900 and 5950 desktops (10GBS NIC's), along with 4 Acer Laptops with PCI 4 throughout and USB 3.2 Gen 2. The laptops all have 2.5 Gbs Realtek adapters and 2 M2 2280 slots which carry 4TB each, hence the need for 5 Gbs Ethernet.
You need to use jumbo frames at 16 K, set receive and transmit buffers to the max (4k), and switch off everything else that you can, with interrupt moderation set to adaptive. Also, make sure the ethernet/usb line ends at an unmanaged switch and not in a router, or you just add to flow control overheads. I managed to get 4.2/4.25 Gbs laptop to desktop, and 3.9/4.0 GbS laptop to laptop. CPU overhead was around 7.5-8.0%, what you would expect with 12 /16 cores on the desktop and 8 on the laptop. This equates to 80-85% of notional throughput; the old 2.5 Realtek USB ethernet units deliver around 290/292 MBs (93% of notional) and desktop to desktop transfers around 1.15/1.16GBs (92.5%).
Why? Well, the problem is that all interrupts and data derived from USB ports need to travel over the PCIE bus, and with NVME drives and GPU's hooked directly into the processor they become third class citizens. 2.5 Gbs Ethernet hooked into USB 3.1Gen 1 will work at rated speeds (there's 50% unused headroom), but while the Sabrent connects at 5Gbs, the PCIE bus then has no headroom at all, certainly not on a laptop. Having USB 3.2 Gen 2 on the laptops does speed things up, allowing the slower 3.1 devices rather more bandwidth. USB devices are not often latency critical, but ethernet traffic is, and suffers as a result. One has only to consider the lamentable performance of some USB 3.1 HDD backup devices for tangible evidence of this. Always use powered units; Seagate Expansion drives (based on DM004 4TB video HDD's) are the best that I've come across.
The software overhead for network file copies is around 7-8%; even on high performance networks with no shortage of host resources, the lack of priority on PCIE 4 bus will degrade performance by another 12% at a minimum based on my results; I suspect that you may have tested a few PCIE 3 devices in your surveys, in which case we can say that what should notionally be 92% of maximum throughput has been reduced to 70%.
Lastly, if you do buy one of these, then buy the Sabrent. The metal case is a useful heatsink (why I bought the 2.5 Gbs Realtek units), it has two decent sized cables, and it's also the cheapest.
some of those adapters are only usb 3.0 like the Sabrent. Did you also test those using a usb 3.1 gen 2 usb port?
Yes. They use the same chip and so while we tried, Gen2 ports did not help
Try UGreen 5GBE-USB, they are lot cheaper (CM312) at $70 usd. And they are metal chassis.
Did you try lacp link aggregation? Tcp/udp will run over USB just fine.
Do these work with truenas as well? I’m just looking for something to get faster than gigabit speeds
Probably not what we would recommend for TrueNAS. github.com/Aquantia
What if you try running the Trendnet on Linux ?
Any updates on these adapters or this objective?
Looking to try this Sabrent NTSS5G here, but wondering if since this submission of this video a year back, whether more has come to light...better devices or a one-year review of these here?
I'm still trying to find an adapter that works for my 2020 Hisense (Android) TV. Have returned a few adapters which weren't recognized.
My 1Gig ISP speed is being reduced to 30 mbps (despite being wired through Ethernet cat 6e) for this TV. Thank you in advance.
No real new chips for these to be based on that I am aware of. The USB 3 5Gbps is the big bottleneck still

Understood. Thank you kindly. Appreciated.
I saw your review link for the Sabrent, but no royalty (override for you) sales link (Amazon) in the Description.
I'll order separately then and see what happens. The TV only has USB 2.0. Hope it works.
could this be a dos/windows copy speed limit that Linus TechTips talked about when they were trying PCI-E network cards with fiber cable???
Considering this seems to be driver related, I'd be curious how this works out on macos and linux. I wonder if anyone has tried that?
Also they didn't go into detail about using the other drivers. You can right click and force the wrong driver on things which sometimes works on these hacked products where they put their own name on the drivers.
