TRENDnet TEG-S380 8-port 2.5GbE Switch Review


TRENDnet TEG-S380 Performance

Unmanaged switches are not necessarily the most interesting components of the switching ecosystem. Still, we wanted to quickly take a look at performance.

The switch itself was able to get 2.5GbE traffic on each of the ports.

We normally would discuss management, however, this is an unmanaged switch so that limits options to discuss a feature that does not exist. Unmanaged switches have been around for a long time, and so we are going to assume our readers understand the implications of an unmanaged switch. Instead, we are next going to focus on power consumption.

TRENDnet TEG-S380 Power Consumption

In terms of power, the TEG-S380 uses an external 18W DC power adapter. This is shared between the TEG-S380 8-port switch and the TEG-S350 5-port switch:

We saw around 5W at idle and the switch has a maximum power consumption of 12-13W. Those are not huge figures, but we simply wanted to present our findings. That 7-8W range is dependent on ports occupied, traffic, and cable lengths. For our readers thinking about using this switch for a WiFi 6/ WiFi 6E infrastructure, this is not a PoE capable switch.

TRENDnet TEG-S380 Pricing and Market Impact

In unmanaged switches, pricing is perhaps not everything, but it is clearly one of the biggest factors. For the TEG-S380, this is a doubly important aspect since there is competition with other 2.5GbE switches as well as 1GbE infrastructure. Let us start with the list pricing:

TRENDnet TEG S380 And TEG S350 Pricing MSRP
TRENDnet TEG S380 And TEG S350 Pricing MSRP

Here we can see that this switch is $189.99 or $23.75 per port. The interesting aspect here is that the incremental three ports are effectively half-price over the per-port cost on the 5-port unit.

We used Amazon and a quick web search for street pricing and this is what we found at the time of writing this review (pricing may change over time this is as of April 2, 2021):

The per-port cost goes down by $1.25 due to the $10 lower street price than the MSRP. Here is an Amazon affiliate link that will pull current pricing:

Just discussing some comparison points here:

  • QNAP has a 5-port unmanaged switch (QSW-1105-5T) that is around $189. The company also has the QNAP QSW-M2108-2S an 8x 2.5GbE plus 2x SFP+ lightweight managed switch at $249. It is clear that TRENDnet’s 5-port offering is less expensive. The QNAP 8-port offering is an example of a higher-end 2.5GbE switch so we just wanted to include that as a discussion point.
  • TP-Link has a $139.99 5-port switch, the TL-SG105-M2 which is similar in price to the TEG-S350. The 8-port TP-Link TL-SG108-M2 is $199 at the time of this writing. $20 in this space is quite a lot.

The reason that $20 is a lot is that it is in the range of an 8-port unmanaged 1GbE switch. Those often sell for $20-25 or around $3/ port.

One side of the equation is that TRENDnet is providing lower-cost 2.5GbE solutions than its competition. The other side is that the cost per port is still 7-8x that of 1GbE switches.

I discussed this with our Editor-in-Chief, Patrick, and we both felt that this was too much of a premium for 2.5GbE ports over 1GbE ports to really drive adoption.

Our hope is that with future generations, the cost of these switches starts to fall significantly. The current move to 2.5GbE is being pushed by the industry. We have recently looked at USB to 2.5GbE adapters, PCIe to 2.5GbE adapters, WiFi 6 APs, NAS units like the QNAP GM-1002 3U Dual ZFS NAS, the low-cost ODROID-H2+ with H2 Net Card Cheap 6x 2.5GbE, the Intel NUC 11 Pro, and even in our recent Core i9-11900K review we used an ASUS ROG Maximus XIII Hero motherboard with dual 2.5GbE ports. We are seeing 2.5GbE become more common, and our hope is that new lower-cost switches drive down access and adoption of 2.5GbE.

Final Words

The direction of the industry in 2021 is clear. New higher-end devices are going to support 2.5GbE. Just the number of devices we have already reviewed, plus those in the review pipeline we can see the transition happening. For some networks, such as the extremely cost-optimized segments along with control networks such as those for server Baseboard Management Controllers or BMCs we do not see those changing from 1GbE this year. For other markets, 2.5GbE is going to have a much bigger 2021 after years of anticipation. This is being driven by the fact that we have low-cost 2.5GbE NICs from companies such as Realtek and Intel.

Against this industry shift, the TRENDnet TEG-S380 is a solid step in what we think is the right direction of offering lower-cost 2.5GbE switches for the market. There still seems like an opportunity to help drive an adoption cycle by getting even lower-cost devices in the market, but as of now, the TRENDnet TEG-S380 is the lowest-cost 8-port unmanaged 2.5GbE switch we could find (at the time of writing this review, prices/ discounts change) on Amazon, Newegg, and a few other sites. As a result, it is a big step for the industry.


  1. It’s a first, more will follow and the prices will drop. I’d like a managed switch for VLAN support. I’d the same format/size as the Netgear GS108 which is so small that it’s easy to hide.

  2. The issue is that hardware cost wise the difference from a 1Gbps port and a 2.5Gbps port is nominal. They are practically the same hardware. We need a breakout manufacturer to start making all of there hardware 2.5 Gbps and price it to sell. That will kick these other companies into upgrading their hardware offerings.

  3. Trendnet TEG-S350 is very similar to the Edimax GS-1005BE, which is available in Europe for around 100 euros. The housing is slightly different, but the PCB is the same.

  4. Nice review. But i was hoping these would be $79.99/99.99. A bit pricy imo. Keep up the great reviews sth. Even non enterprise tech is good for us.

  5. Finally we have sub-$200 5 or 8-port 2.5GbE switches and TRENDNet is the first to blink in this 2.5GbE switch overpriced market from the main consumer networking brands. Null doubt the other usual culprits will soon follow with models made out of the same factories in China.

    CONCLUSION: You will find sub-$100 2.5GbE switches in 1+ year. It will be then the time for the manufacturers to rinse and repeat for 5GbE and 2+ years later for 10GbE. It’s called “maximizing the opportunities to suck your hard won pesetas out of your wallet.”

    @Rohit Kumar: do you know which chipset is used? Just to know what the other brands will also use.

  6. can you please check out the “Zyxel Multi-Gig 12-Port”? never heard of this brand, but 2x 10gb sfp+, 2x 2.5gbe, and 8x 1gbe for $150 sounds like a compromise that’s a little more useable than 8x 2.5gbps ports for many home networks / devices.

    i.e. 10gb ryzen workstation, 10gb uplink to network closet / nas / etc., 2.5gbe to wifi hotspot, 2.5gbe to laptop w/ usb network adapter, and 1gbe for everything else.

  7. Wouldn’t it make more sense to spend a little over 3x the money, get 50% more ports, and all 12 ports are capable of 1/2.5/5/10Gb?

    I just to see the value proposition of a minor incremental upgrade like this, especially when 2.5Gb is not the standard port in most devices. I.E. If I am going to rip and replace my 1Gb equipment, I’m going to go for something that I won’t be trying to replace in another 3 years.

    And don’t get me wrong, I understand $599 list is a lot of money. However considering the equipment wouldn’t have to be replaced when there is a push to 5Gb, and again eventually when there is a push to 10Gb, then you could consider that a cost savings for 50% more ports that can all do 10Gb if needed.

  8. Dan: on mikrotik: FAN count = 4. This is a deal breaker here. Otherwise it may be fine hardware. Honestly I’m looking at least for managed 8 port 10GigE in fanless configuration.

  9. Comment intended for James Hollis, who was replying at the Y T video of this review:

    If you happen to remember this odd request, we’ve got an enormous amount of work done with 2 almost identical ASUS motherboards: the P5Q Premium and the P5Q Deluxe. Both were stabilized several years ago on Windows XP.

    It would be great if we could find a 2.5G driver that is compatible with Windows XP x32.

    The P5Q Premium has a vacant x1 slot; and, the P5Q Deluxe has a USB 3.0 add-in card installed in an x1 slot, which I almost never use. So, I can remove that add-in card and insert a 2.5GbE NIC in that slot instead — assuming a working driver is available.

    The Realtek website does list an XP driver for the RTL8156 controller:
    “WinXP Auto Installation Program”

    Google “WinXP Auto Installation Program”

    BUT, it doesn’t install, no matter what “path” I choose when updating the driver in Windows Device Manager.

    I understand that XP is “End of Life”; however, as Patrick has already mentioned, lots of SOHO users are downgrading their older PCs to duty as LAN storage servers. This is a much better use for that hardware, than dumping it in the nearest solid waste landfill (just my rant, OK?)

    (Maybe Rosewill can be persuaded to develop a custom driver for XP x32?)

  10. I have two LAN storage servers. I am using linux and software raid. Right now I have a 2.5g NIC in each, and my main computer has a 2.5g NIC. I am direct connecting the storage servers to my main computer. It turns out that using software raid, I can only read and write about 300 mybres/sec so 2.5g is a good speed for the NICs.

    Since I don’t have a dual nbase-t NIC in the main computer, I need to swap cables when I switch between LAN servers. Having a nbase-t switch would eliminate that need. I really need 3 ports for the computer and 1 port to connect to my main network. More ports might be nice, but I don’t want to spend a lot extra. 5 port switches would be ideal, but I am waiting for the price to drop a bit.

  11. I know the switch isn’t managed, but is it smart enough to not get confused by, or drop, or mangle any VLAN tagged packets going through it?

  12. Thanks for your great review. The Trendnet gear (8 port & 5 port 2.5Gb) is worth looking into for availability.
    FYI, the QSW-M2108-2S has 8 each 2.5Gb ports plus 2 each 10Gb SFP+ ports. With QNAP free QSS Management Interface link aggregation is supported (multiple ports in and multiple ports out). Thanks again for you professional reviews. Always very helpful.

  13. Thanks. I purchased 2 of the QNAP 5 port 2.5Gb switches in 2020 at different times and paid below $110 for each. Both online from B&H. I would purchase an unmanaged 8 port 2.5Gb switch for ~$140-$150 range. Thanks

  14. Other than fewer wires, does the price premium of 2.5G really make sense over bonding 3 or 4 cheaper 1G ports on a server to provide better throughput to an office of 1G workstations? With LACP offered by most managed switches and Intel 4-port gigabit cards being commonplace, the overhead of three extra patch cords seems much more bearable than re-cabling an existing CAT5e plant and upgrading endpoints.

  15. I managed to grab the QNAP 5 port for 99 US$ at B&H when it was initially listed. Rock solid so far.

  16. Don Wright, 2.5GBASE-T works with Cat 5e cable, so there’s no need to upgrade the cabling. It was designed specifically to work with Cat 5e, and 5GBASE-T was designed to work with Cat 6. I think distance is 100 meters for both.

  17. @Bob. TP-Link has unmanaged 5 and 8-port 10G copper switches TL-SX105 and TL-SX1008 launching very soon.
    They are already listed in Japan and the UK and Tomshardware speculates that US prices could be about $275 and $450, respectively.
    If you want managed, Ubiquiti is about to launch a 4-port 10G copper switch for $269. It’s on their Early Access page now (requires a Ubiquiti account to view)

  18. Once I pass into triple figures for a small switch, I have a problem with it being unmanaged or without a faster uplink. Any office situation that can justify upgrading the NICs to go from 1Gbps to 2.5Gbps must have a serious networking business case – so the backbone can probably justify 10Gbps – which is possible on mid-range NAS units and sub £1k servers.

    TP-Link do a 8-port 2.5Gbe switch, but it also has two 10Gbe uplink ports (TL-SG3210XHP-M2). Add the 240W PoE budget, smart features and the Omada integration, £300 is pretty reasonable (SFP pricing aside). The only problem then is how loud is it on a desk.

    I see Brian B also has a recommendation for a 2.5/10-uplink switch above.

  19. For me a switch is reasonably priced, once it has a lower per-port cost as the devices that connect to it. And for a couple of years that has now been the case, even for 10Gbit capable NBase-T switches like the Netgear XS508M 8 port which retails at €380 including taxes in Europe.

    And while that has a fan, it’s still a lot quieter than the Buffalo BS-MP2012 switch, that I started with (I had to pick up on Patrick’s tip to quieten it via Noctua fans!).

    Greater than 1Gbase-T PHYs, simply eat power somewhat linear to the speed they offer and that’s why this has a metal case, just like the ASUS XG-U2008 needs for only two 10Gbit ports (won’t do 2.5/5 Gbit, and coffee never gets really cold on top).

    Once you understand the signal modulation complexity they need to employ to push information across those copper wires, you no longer complain but admire what they accomplished. The only escape to power and cost is to go digital via short direct connect cables… with their own challenges.

    Too bad even Thunderbolt networking is more trouble than relief, because ports are too dynamic for current network stacks and protocols to handle in a logicallypersistent manner.

  20. I agree with the $9 per port price point. I currently have a nas and 1 desktop with 2.5g ports and would be willing to upgrade my other desktop when the switch price is right
