What’s the Difference in USB 3.1 Gen 1, Gen 2 and USB 3.2? - DIY in 5 Ep 132

- There is a variety of USB types, it is so confusing! We’ll demystify the naming process so that you know exactly what you are getting and whether or not it fits your specific needs.
USB (Universal Serial Bus) is an industry standard that determines specifications for cables and connectors used for short-distance digital communications, connections and power supply. The USB Implementers Forum oversees the naming and maintaining these standards since USB 3.0 was released in 2008. So if you think the USB naming conventions are a bit confusing they to blame.
At the beginning USB 1.0 was released in January 1996, although not widely adopted until the release of USB 1.1 in 1998. Two years later, USB 2.0 was released, bringing with it not only higher bandwidth but also specifications for mini connectors, micro USB connectors and battery charging. USB 3.0 was released in 2008 and it was a vast improvement over 2.0’s transfer speeds of 480 Mbit/s. 3.0 introduced a SuperSpeed transfer mode, shown with a distinct logo and blue inserts in ports. Ah, these were the good old days when you could clearly see the difference between different USB options. But alas, this simplicity doesn’t last long.
USB 3.0 eventually became known as USB 3.1 Gen 1 - yep, they are the same thing. Then USB 3.1 Gen 2 came out, bringing speeds double what we had in Gen 1 - 10Gbit/s as opposed to 5Gbit/s respectively. Originally, the naming conventions Superspeed USB for Gen 1 and Superspeed USB+ for Gen 2 were pushed, but never really caught on, and some manufacturers even added the speeds 5Gbps or 10Gbps to their specs to help make it clearer. But most of the industry stuck with USB 3.1 Gen 1 and USB 3.1 Gen 2.
Then, in 2017, we got USB 3.2 and saw the gradual move from USB-A to USB-C connectors. USB-C supports higher transfer speeds and faster charging, and as such is becoming the new standard. Because of this, we see USB 3.2 in four different variations. USB 3.2 Gen 1x1 - offering the same speeds as USB 3.1 Gen 1, and therefore the same as USB 3.0. USB 3.2 Gen 1x2 offering 10Gbit/s transfer speed in USB-C form factor only. USB 3.2 Gen 2x1 - 10Gbit/s speeds in the standard USB-A form factor (just like USB 3.1 Gen 2). And USB 3.2 Gen 2x2 - 20Gbit/s transfer speeds, USB-C only.
It’s confusing but let’s continue. Thunderbolt is the brand name for Intel and Apple hardware connecting peripherals to a computer, and while the first two generations used a mini display port connector, the latest version Thunderbolt 3 uses a USB-C connector. It is precisely this combination of USB-C Thunderbolt technology which will take us into USB4. USB4 promises increased bandwidth, 40Gbit/s transfer speeds, Thunderbolt compatibility, USB-C connections and, with any luck, intense minimizing of USB user confusion.
The good news is almost all this is backwards compatible and again, hopefully will be more streamlined as we move into the era of USB 4. Do you have any specific USB-related questions not answered in this video? Please go ahead and leave them in the comments and we’ll do our best to answer them.
This was always the dumbest naming scheme I've ever heard, lol...It's easy, just keep going up in numbers, 3.0, 3.1, 3.2, 3.3, 3.4. They just like confusing people, clearly.
THERE ARE MORE USB 3.0 BUT AT HIGHER NUMBER? WHAT
Clearly the folks behind this technology are not very organized lol. Computer guys am I right? lol
Shopping on Amazon, about 50% of devices that run USB (not including cables) support USB 2.0, 30% support 3.0 and 3.1 Gen 1x1, 10% support 3.1 Gen 2x1 and 3.2 Gen 2x1, 5% support Thunderbolt 3, 3% support 3.2 Gen 2x2, and 2% support USB4/TB4.
However, try to look up anything that delivers 10gbps and all you'll get is USB Type-A 3.0 and 3.1 Gen 1x1.
Sellers have had to start combining the letters with the numbers to avoid confusion (e.g. Thunderbolt3, USBC, Gen2, Gen2x2, TB3, etc.), so I'm glad USB40 is not only going to have that by default, but it also doesn't need the decimal point so that we don't get results for USB4.0 when USB4.2 comes out (because Amazon has no clue what punctuation is).
@@loop5720 Yep, I ended up with an "extra" M.2 PCIe drive, so I decided to use it as a 512GB USB drive....buy a little enclosure.
Oh the choices....
Settled on USB 3.2x2, which is 20 GB/s, and you can plug it into USB A(@USB 3.2x1 OR Thunderbolt 3 ports, which are USB-C connectors and get the 20 GB/s rate.
You can also get one that runs full Thunderbolt 3, which is 40GB/s, but they are about $200!!!
Mine was $35.99!!!
40GB/s can wait at $200!
wait until they hear about π
Thank you! I'm building out a PC and it has USB 3.2 Gen 1 and Gen 2 ports and I was a bit confused. This has helped immensely. Subscribed.
Got asus z690 motherboard with USB 3.2 and Mb500 cooler master Cabinet with USB 3.0. Are they compatible?
Thanks Mia!
So I'm building a pc and my motherboard has a USB 3.2 gen 2 but my case needs another gen 1 port and says I need a USB gen 2 to gen 1 Header Plug, how does that look ?
Geez, not seen Trish since sourcefed
What cable do you suggest to connect an Oculus Quest to a PC that only has USB 3.0 ports and no USB-C ports? HELP!
Soo if I bought 3 portable usb c monitors and I wanted to use usb c to power it and it give video feed for all 3 but don’t have 3 usb c ports can I usb a usb a to usb c to get video transfer through those 3 ports?
I'm all wireless. Bring back the barrel charging ports.
Why can’t somebody just explain the difference in the sizes of the connectors? I really don’t care about transfer speeds at this time. It’s a simple question: what are the difference in size of the head (the metal part) on USB 3?
I wonder if USB-C fits in USB-C 3.2 gen2 hole, can you answer it?
Hey there, the difference between USB 3.1 Gen 1 and USB 3.1 Gen 2 is only in terms of speed, but the connector port is relatively the same. For more info please visit our site kings.tn/3I8jU7v
Thanks a lot :)!@@kingston
What about display through usb ?
tişört harika yanlız...
Looking lovely always Trisha
Wait, blue doesn't mean anything?
*looks at my old dell motherboard with 8 USB 3.0 ports, and zero blue*
Never has
i need a usb girlfriend
Great vide, bad audio and distracting shirt tho.
Lovely bra!
you look like my ex bf
almost as logical as cpu and gpu naming. can we just use colors? usb purple maybe
Love the voice + eyeglasses is like Wonder woman !
Yes, yes she is but if anyone watched your last update she is also batgirl
@Hatori Ibuki no I think it's her secret identity.
Have you even seen wonder woman
didn't even notice she was wearing glasses
Learn more about the different types of USB standards here: www.kingston.com/en/usb-flash-drives/usb-30
what the heck does "by 1" or "by 2" mean in USB 3.1 gen 1x2?
How the heck can a generation have a "by"?
Explain what that even means -_-, don't just start saying it like it's obvious.
here is a better job done:
www.cnet.com/how-to/usb-3-2-explained-making-sense-of-current-and-confusing-usb-standard/
"We now find ourselves in a similar spot with USB 3.2. The newest, fastest version of USB 3.2 offers a max speed of 20Gbps and is called USB 3.2 Gen 2x2. (The 2x2 means it's the second generation and has two 10Gbps lanes to achieve its maximum throughput of 20Gbps.) The older USB 3.1 has a single 10Gbps channel and is called USB 3.2 Gen 2. Then there's USB 3.0, which is now called USB 3.2 Gen 1."
@@gwho Thank you. That c|net link has the most helpful clarification of this stuff I've seen yet.
What a nightmare these supposedly standard, unified ports & cables are proving to be.
Now watch: As soon as the second generation of USB 4 comes out, USB-IF will give all the different USB-C generations brand spanking new USB 4.x names.
usb
.... which ones can handle a egpu even if throttled? can a Asus Q405UA usb c handle a external-gpu?
The USB standard is more than just dataspeed. It is also about power output => charging speed. You completely ignored this aspect.
Thanks for your video on USB naming conventions and their comparison. I think perhaps what is needed though is a followup on SD or USB drives that are actually fast enough to work on these faster ports. What really surprised me that even 3.0 USB or USB 3.1 Gen1 as it is known now has some vastly different transfer rates among drive products. In some cases you may not even get 3.1 Gen1 max transfer rates. So it seems that the spped of the memory used in that product ultimately determines how fast that device will be. I have been contemplating buying a 3.2 Gen 2+2 adapter card but first I need to know what drives I now have to buy to realize these faster speeds. I would appreciate if you can research this and perhaps guide us in making those choices.
Intentionally confusing to screw consumers into buying multiple wrong products. Disgusting naming scheme. Something so blatantly anti-consumer should be illegal.
It's a shame nobody ever mentions the great grand father of both USB and Firewire. It was the great Nintendo Gameboy connect cable that started it all, allowing for ad-hoc 1-1 or for up to 4 devices using a little hub. Nowadays, Thunderbolt 4 and USB 4 are aiming to become fully cross compatible and after USB4 is out, I wouldn't be surprised to see small driver updates for existing Thunderbolt 4 devices to become fully usb4 compliant. They already are USB3.2 Gen2 (and backwards) compliant.
You'd probably enjoy the book Super Mario: How Nintendo Conquered America, if you haven't already read it.
Thanks, Trish as always you're the best and HAPPY THANKSGIVING WEEKEND EVERYONE from Canada 🍁 stay safe and have fun.
This lady shows us the best facial expression on thumbnail. It says all. Thanks for representing our feeling on USB chaos!
Fact check: USB 3.2 Gen 1x2 is not just for type-c but also type-a, depends upon the speed both ends negotiate.
How? Hey excuse, got asus z690 motherboard with USB 3.2 and Mb500 cooler master Cabinet with USB 3.0. Are they compatible?
Question: USB 3.0 HUB 4 ports. If I have three USB 3.0 devices plugged in and one USB 2 device, does the whole hub run at USB 2 speeds?
The cable that connects the hub to the computer determine the capability of the hub, and from there the connectors going into the hub determines the actual speeds for those individual connections.
In short: As long as you use a 3.0 cable between the hub and the computer, the other devices will transfer data at their intended USB speeds, separately.
Mam my laptop has Type-C USB3.2 Gen1 .
Can i connect it to my monitor display port any which way to achive 144 hz of my monitor ?
SAme questionnnnnnnnnnnnnnnnnnn
thanks for the video! but how do i know what specific usb port my computer have? like i know it's 3.1 but i want to know if it's gen 1 or 2
nobody confusing girl ... USB A connector is the same as the USB3.1 connector for everything Usb С NOW NOT NEW HAVE IT A LOT OF DEVICE AND ADAPTER - SO WHAT CONFUSING YOU? OLD ONE LIKE MICRO OR Printer USB? everybody use a maximum of 2 types and maybe sometimes - s... of Apple and Intel to do something that looks like bit not working don't need anyone will wait for USB4 now have USB3.2 C GEN2 ALL READY MORE WHEN 2 YEARS YOU HAVE FASTER SOMETHING - EVEN EXTERNAL SSD IS 10GBIT/S IN DREAMS. APPLE ONLY COMPANY IN THE WORLD THAT REFUSES TO USE STANDARD USB APPROVED BY MUCH BIGGER AND REAL MANUFACTURERS! APPLE DON'T DO NOTHING Ios on Arm on Desktop with so old electronics with this price tag. Only in the USA so much like APPLE - WHY WHEY IN SCHOOL AND IT'S MUST BE STOP IT COST A LOT AND PEOPLE GUT THIS VIRUS - MY 5 OLD CAMERA BETTER WHEN YOU NEW BY THE SAME MANUFACTURER WHO REALLY does IT NOT APPLE ONLY SOFTWARE - THUNDERBOLT WHO SUPPORT NOBODY - I WANT TO SEE NEW TECHNOLOGY FOR EVERYBODY FREE AND NOT CABLES FOR APPLE FOR 20$ SD CARD NO... 60% OF PROFIT ON ONE DEVICE WHO BUY IT ////// BATTERY DYING FAST NEW ACCESSORIES COLD BATTERY BANK ONLY WIT MAGNET HOW TO GO WITH IT?
I am considering two laptops at present.
Machine 1 has a slower processor, with faster ports.
Machine 2 has a faster processor, with slower ports.
Which is the better option ?
Faster processor.
Machine 3 with more memory, slower processor and slower ports.
USB IS USB!!!
-Mr. Incredible probably
praying that usb 4 will be orange color or gold. makes it fun and less confusing!!!
great video trisha!!
they will make it blue in different hue for confusion, wanna bet?
thank you very genuinely for this explanation :)
The BEST explanation I've seen so far. THANK YOU!!!
My USB cable has the letters SS on it.
Should I be worried?
Not at all, the SS stands for SuperSpeed!
I CAN NOT find a usb to usb-c 10 gig around 9-10 feet long. What am I missing here? I need to record 4k to a desktop at 60fps and also be able to live stream at 1080 60fps. I have a sit/stand desk the reason for the length needed.
@4:30 yeah... emphasis on the ALLMOST all. i learned this the hard way when my 3.2 (apparently 3.2x1 i just learned) AOC (active optical cable, also important feature for lenghty cable routings) is not backwards compatible... luckily i was in time for refund
Asus ROG Strix Helios ATX Full Tower Case has a front panel USB 3.2 Gen 1 Type A port, but the Asus ROG STRIX Z590-E GAMING WIFI ATX LGA1200 Motherboard does not have sufficient USB 3.2 Gen 1 headers. The case USB 3.2 Gen 1 Type A port will not be usable.
What can i do to fix this problem?
Hello, I have an SSD hard drive, but from transferring data, the speed is 5 MB/S, how do I get the speed you mentioned in the report?
what the heck does "by 1" or "by 2" mean in USB 3.1 gen 1x2?
How the heck can a generation have a "by"?
Explain what that even means -_-, don't just start saying it like it's obvious.
Beautiful as always, great content. Great explanation.
great. but i would have also really liked you to be even more dumbed down and say. that yes all these usb 3's all have the same connector until usb c. Atleast I assume that is correct. Is
it?
So essentially we haven't really made any progress since 2008? You can't even find a proper 10gb/s usb >4 port hub under 150$ out there -.-
I have no questions. You answred all my existing questions, and then some. Thanks so much! I'm unlikely to retain any of tis craziness though 😜
late to the party but which ones support display? Very annoyed when I got the Surface dock 2 from Microsoft and it only supports display on two of the 4 usb-c ports.
From my experience, a lot of USB 3.0 & 3.1 interfaces on PC never compatible with old USB devices.
Let me guess:
5Gbit become USB4 Gen1x1
10Gbit USB4Gen1x2
20Gbit USB4Gen2x2
40Gbit USB4Gen4x2
Hhahahaha
I have a standard looking USB Port on my new Desk Top PC Motherboard and one that looks like a USB C, both are Red- What are they?
OH WHY DIDN'T THEY JUST GO WITH
USB 3.0 5GB SPEED
USB 3.1 10GB SPEED
USB 3.2 20GB SPEED
DUAL LANE YES OR NO
SO MUCH SIMPLER
hi i have an monitor with an usb-c 3.2 gen 2 for video input & my pc has hdmi + dp output. does kinston has an device that can connect my desktop to my monitor?
anyone know where i can find a usb 3.2 gen 2x1 a port to c port? I literally typed it in on amazon and google and could barely find anything
playback speed 0.75 is highly recommended 😂
Thank you for your information sister😀
Thank you !
My type c samsung super fast charger messed up my Playstation 5 controller when I used it to charge controller.
is usb 3.2 have anything to do with usb c? i saw specs for samsung tab s7+ and charger type says usb 3.2
Just looking for USB crash course and I get a SourceFed flashback!
hey beauty how are you me have hp z620 how installe pcie ssd nmve boot system thank you
Does any usb 3.2 charging are compatible or are MHL support for mobile screen mirror wired cast?
Hello there we suggest you check with the USB organization here for more details www.usb.org/usb-32
You talked alot about the speed, but what about the amps? some put out 3A and other put out 5A
I have an Acer Nitro 5 AN515-57 with a USB 3.2 Type-C, Gen 2 connector. I also have a couple of USB-C hubs. I can't get any of these hubs to transfer video signals from the laptop. Is there some limitation on the USB-C connection on my laptop that is not described well in this video? Thanks in advance.
If you are having issues on your system you may want to verify that your System and System Drivers are updated to the manufacturer's recommendation. You can also check to see if the peripherals you are connecting to your laptop with the issue malfunction on a separate system. We suggest you contact the computer manufacturer's Tech Support for further troubleshooting.
Wow, toute l'info en 5 minutes, et clair avec ça. Bravo
Can I put a usb 3.0 in a USB 3.1 Gen 2 port/plug ( which in on a new Mac air that ) or is there an adapter? Sorry I probably sound really dumb.
(My external hard drive has a usb 3.0 ( think it’s just 3.0) & if I get a new MacBook Air, will have a usb 3.1 gen 2 . Hence the question (I’m sure there are ways to sort it all out , even if I needed to get someone else to organise it. And I am going to be buying a new external hard drive now as a backup. )
Hey Paige This is a thoughtful query. The ports and the majority of the more recent Gen USBs are backwards compatible. You can always check with the manufacturer to see if there are any limitations, but you should be able to plug in the USB 3.0 without any issues. Additionally, you may learn more about it here. kings.tn/45YZ70y
On the same page, you can also get in touch with our Tech Support if you require further information.
This was very helpful and straight forward!
can a usb 3.2 gen 1 motherboard go into usb 3.2 gen 2 case
lol I,m stilling using USB 2.0 outdated version :)
LOL I had exactly the same facial reaction as the thumbnail before reached here. Btw the woman is my favorite.
so 3.1 gen 1 is compatible with usb 3.2 gen 1 header on mb or nope?
Ok so what I've known from research about USB to video output:
USB 2.0: yes
USB 3.0: yes
USB 3.1 gen 1: no?
USB 3.1 gen 2: yes
I do have a HP reverb g2 VR headset and it requires USB 3.0 but when I upgraded my computer, it only comes with 3.2 gen 1, 3.2 gen 2 and 3.2 gen 2x2. I tried every USB ports but the reverb headset doesn't work. Any suggestions.... Thanks....
Hey there this looks like a case for HP Support to check for compatibility and possible updates to their product: spr.ly/6050KyPSC
Yes I clicked the thumbnail for the information 🌚
question: if i buy a usb 3.1 gen 1x2 (so usb-c only) and i stick it in a usb-c to usb-A gen3.2x1 hub, does that work?
so with the cable connecting the hub to the pc
Yes it should just remember that it will function normally at Gen 3 speeds.
Does usb type A mean the other previous usbs? Because I'm gonna buy a laptop with usb 3.2 gen 1 and I'm really concerned because i can't find a keyboard and mouse, most of them are usb 2.0.thanks!
Hi there for more clarification see our lineup and here and filter just the Type-A connectors to give you a visual. Here we made it easier: kings.tn/3yMVZGX

I hate when the transfer speed goes to one or two mega bytes per second for NO reason even on USB 3 port. Huge files are ok, transfer can go up to 150 mega bytes per second; but when you have thousands of small files... just give up.
Hello Gunther Arnold,
When transferring a folder with multiple files, we recommend compressing it first and transferring it as one big ZIP file.
Transferring a folder with multiple files over USB can slow the file transfer speed due to more metadata overhead, fragmentation, and heavier disk usage. A single compressed file can be faster as it reduces the transfer amount of data.
@@kingston Yes. Doing so, I will make the large file, but... no, I want something like an e-sata. I have sensitive data on my laptop and I want to run windows from an external drive.
is USB-C® 3.2 Gen 1 capable of video? I have a Vivobook-Pro-15-OLED-M3500 and I want to connect a monitor using this port (and I'm not successful)
Hey there USB-C can be used to transmit audio and video if your devices support it. You can read more about it here spr.ly/6053JcKKx
Hi, how will i know if my USB 3.2 Gen 1 is a x1 or x2?
hello can i have a multiple screen with my laptop with usbC 3.1 gen 1 like thunderbolt do ? cause laptop with thunderbolt are more expensive and i want to have 2 big screen with my laptop connect. Thanks a lot :)
Hello,
There are different varieties of type C usb ports, so check the specs on the system to confirm that port is a full type C and and manage 2 monitors. Our Nucleum will not manage two video signals, as the HDMI is the only one that supports video.
Thank you
Ahhh AHHHH Ahhh
AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH...
Ok I'm free now
did you coom?
@@SZF123456 I think he coomed.
Rarely cud keep an eye contact... Hit like if you agree 😳😉
Wait so will i beable to plug the 2.0 into the other on the motherboard
I have a question. I want to buy monitor with USB 3.0 but my laptop have only ports 3.2. It will be connectable?
Hey there if the monitor is connected to a 3.2 USB Port it should still be fine since most ports are backwards compatible. However to be absolutely sure, reach out to the manufacturer of the laptop for further information.
Does USB 3.2 comes in external HDD
Scrap all the 3.2/3.1/4.0 nonsense and just give us one usb solution with 80gbps period
Hi there, we like other manufacturers are simply adhering to the Universal Serial Bus specification set forth here www.usb.org/about
MY BRAINS STOPPED
My kingston 1Tb nvme m.2 pcie 3 has very slow transfer. I use it as external drive.
Hi there, what model SSD do you have and on what system were you experiencing this issue? The performance can be affected by the type of format it has and the native port on the system. If you need help with your Kingston drive, please visit our support page here: kings.tn/3oKImp8
Thank you.
Ok, and if I name my son, Usain Thunderbolt Gen2, will he run double speed like Usain Bolt, you know, Gen1?
Thanks for this important video. It seems you have to do one about USB and Thunderbolt norms very frequently as this changes at lightning speeds nowadays...
Back in the day they designed a shovel. And it's design remaind through centuries up to this day. O well.
They should make one only thing once and for all. Basically using USB-A format and only develop that cause it's not as flimsy as USB-C. For most use cases USB-A Gen2 will do I think. But that's just me. If course on phones you'll need something like USB-C. But they should provide a round 2-pole charging socket on phones instead of wearing out the flimsy USB-C ones.
Mam I have MSI GF65 THIN and 144Hz refresh rate . It has Type-C USB3.2 Gen1 . If I connect an external monitor which is 144Hz refresh rate , then what Cable I should buy ???? Type C to Display Port???????????? Please tell me ..... I'm very confuse
just to clarify i can plug any usb into usb 3.1?
Yeah I’m totally interested to the usb tech 😅
ys how can I check what usb gen my macbook has ?
I still don't know what i'll get if i check Kingston’s web site.
USB 3.2 Gen 1x1 vs USB 3.2 Gen 1x2 - on your web site is only USB 3.2 Gen 1
So what will I get? If I cross check if USB-A or USB-C connection I can guess what it will be…
Make it easier for all and only write the theoretical read and write speed - and keep USB 3 for all
Crazy marketing.
@Trisha, nice nerdy top
I have a question cause i have the thunderbolt symbol in my laptop but is not in the shape of the thunderbolt 3 its in the shape of a regular usb and im confused cause im new to this
Check out this guide to help identify ports on your system, it also has a listing of models that have Thunderbolt 3 ports kings.tn/3yv0lzu
me have E5 2069 v2 need of changer for E5 2697 v2
コネクタ形状の違いも見たかった
I also wanted to see the different connector shapes.
Nice, very nice move Kingston ;)
so basically i bought a thunderbolt 3 connection external drive and i tried to use it on a usb 3.0 port and it didn't fit so i was pretty confused, i accidentally plugged the thunderbolt 3 into my hdmi slot and my computer shut down, which scared me, i returned the drive not really knowing.
