Review Plugable 2.5 Gigabit USB Ethernet Adapter


hey everybody get slaw and side-bend today we’re taking a look at an Ethernet adapter that plugs into your USB port nothing new about that right well this one happens to be a two and a half Gigabit Ethernet adapter which is faster than the one gig adapters we typically see and we’re going to see what you can do with one of these why you might need one and how this individual one performs here in this review what I do want to let you know in the interest of full disclosure that this came in free of charge from pluggable who manufactures this device all of the opinions you’re about to hear are my own nobody is paying for this review nor is anyone reviewing or approving what you’re about to see before it was uploaded so let’s get into it now and see what this adapter is all about so let’s take a closer look now at the hardware this is pretty much a regular Ethernet adapter if you are connecting it to a gigabit switch it will work exactly the way your current Ethernet adapters do they say on the packaging that you can use a cat 5e cable and get the two and a half gigs speeds but I would suggest probably going to a cat 6 cable at a minimum especially if you’re going over longer distances the device itself just plugs into your USB connection on your computer and you’ll notice here that it’s a USB a connector because USB 3.0 Transit’s five gigabits per second over that USB cable and this only needs two and a half so it should work within those bounds but it also has a USBC connector here on the cable if you want to plug it into a macbook or other device that has USB C onboard and of course USB C is a confusing standard and even though you’re connecting it to a USB can see connector it’s only running at five gigabits per second this is not a Gen 2 USB device just Gen 1 but when we do test out the throughput in a few minutes we’ll check it both on a direct USB C connection and then through a USB a

connection just to see if there’s any difference in speed now just buying this adapter does not get you faster ethernet speeds it has to be plugged into a switch that’s capable of running at this bandwidth now I happen to have this rather expensive one that I bought a little while back this is a Netgear switch that has four 10-gig ports on it however this will of course be backwards compatible with one gigabit ethernet and it works with five gigabit and two-and-a-half gigabit so when we connect this up in a minute or two you’ll see that we’ll have one green light on the right-hand side when we’re connected to the switch but if you plug this into any other gigabit ethernet switch it’s only going to run at one gigabit now the question is who needs these things if we’re all running on the slower internet connections well a lot of folks now are getting gigabit fiber Ethernet connections from their ISPs and you can easily saturate that full gig and maybe not get your full performance out of it something like this would allow you to get better performance out of those high-speed fiber connections especially the ones that go north of one gigabit if you’re transferring large files throughout your home or office you’ll be able to transfer them twice as fast through a single adapter again provided you’re hooked up to the proper switch so limited audience initially for this but I think over time as connections get faster and files get bigger more of us will be using these things the price point on this is $39 so it’s significantly less than some of the 10 gig adapters that are out there and I can see two-and-a-half gigabit becoming more prevalent in homes first versus the ten

another interesting thing when you compare a two-and-a-half gig adaptor to a 10 gig adaptor is the size so this is a Thunderbolt 3 10 gig Ethernet adapter and at the time I’m recording this video this is about the smallest one you can get so it’s quite a big difference in size here but I would anticipate within the next year or two this will soon be about this size but right now if you want something small and portable two and a half gigs is about all you’re going to be able to do at this size and price point so let’s get all of our equipment hooked up here and start running some tests and see if we can push two and a half gigs over this USB adapter alright so we’re going to now hook this up to my max I’m going to plug the adapter into my max USB C port now on the switch here you’ll notice we’ve got a few more things connected so we have a 10 gigabit connection right now over to my Mac Mini and when I connect up the pluggable device here what we should see on port number 2 when I plug it in is one green lights on the right hand side to indicate that it’s getting a two-and-a-half gigabit connection it might be hard to see here but indeed it is just got one light lit up here and we’re good to go there the adapter here is blinking as well and now what I’m going to do is load up my Mac and we’re going to run a program called Wi-Fi perf and what this does is it pushes a whole bunch of data over the network and we’re going to be pushing that data to the Mac over there so that Mac has 10 gigabits of bandwidth to play with and we

should be able to saturate the full 2.5 on this adapter if all is working properly let’s give that a shot alright so we are ready to run the iperf test here we’re going to click on run to push data over to that Mac Mini and what you want to look for is right where my mouse is here under that bandwidth column and as you can see we’re going at pretty much full blast here this is just over 2.3 gigabits per second there’s always some overhead when you’re doing these kinds of tests but this shows us that if you’re hooked up to the right equipment on a USB C connection this will give you the bandwidth that they’re advertising and if you have a switch that can take a two-and-a-half gig adapter you will benefit from just about every inch of the advertised speed here which is really good to see and we’re going to now check and see how it does when we plug it into a regular old USB a connection just because this Mac has some pretty fast USB C port so now we’re going to try to slow that down a bit and see if it impacts the performance all right so we’re going to put the USB a adapter over the USBC cable here get that to snap in and now I’m going to connect this up to this little hub that I’ve got here that has a USB 3 port but this is one of those gen1 slower ports so we know that this will be a slower port versus the one we just had it connected to directly to the Mac alright so we’re going to jump back to the max screen now and run that very same test again but now through that slowed down USB a connection and there you go we’re getting pretty much the same bandwidth now your mileage of course is going to vary based on your computer’s USB so you may or may

not see these kinds of speeds on an older computer but it looks here as though we’re getting the full speed whether we’re connected up to a five gigabit per second USB a port or a 10 gig USB C so altogether it seems like we’re getting good performance out of this adapter so that’s going to do it for this look at the pluggable two-and-a-half gig adapter it seems to be performing as advertised I think this might be something we come back to in future videos because I’ve gotten some feedback as I’ve been live-streaming the recording of this review to try it out with Synology nas devices so maybe we’ll plug it into some other stuff and see if we can squeeze some more network performance out of things that have been locked at gigabit speed so if you have some suggestions for what we can plug this into let me know in the comments down below and we will come back and do some follow ups with this in the near future if you know of any five gig adapters also let me know down there too and we’ll try to get one in for review as well that’s gonna do it for now until next time this is LAN Simon thanks for watching this channel is brought to you by the lon TV supporters including gold-level supporters the four guys with quarters podcasts Tom Albrecht Rick the stood Oh Kris alligretto Kalyan Kumar if you want to help the channel you can by contributing as little as a dollar a month head over to land TV slash support to learn more and don’t forget to subscribe
