If the USB-IF had an ounce of common sense, they would drop all the "3.1" and "3.2" and "Gen" business. Just make it "USB 3 5x1" for the original and "10x1", "5x2" and "10x2" for the rest. There, that's all the relevant information in a simple compact form: the (third) generation of the USB spec, the base speed of the data lanes, and the number of lanes.
They got me, when I was buying my laptop it stated it have USB 3.1 gen 1, ok I assume great it have the 10Gbit one, because at the time I knew usb 3.0 is 5Gbit and 3.1 is 10Gbit, did not know they rename it. I still don't understand why they rename 3.0 and 3.1 it was easy to understand and to explain to someone
This video was extremely helpful in understanding why the naming is complex. Now I think about the USB number in 'USB Y.Z' as the "meta scheme" number. So reading "USB 3.0" I think "original scheme, so just the third major USB". If I read "USB 3.1" I think "Speed scheme. Gen 1 is 5Gbit, Gen 2 is 10Gbit". If I read "USB 3.2" I think "Lane scheme. So Gen 1x1 is 5Gbit, one lane. Gen 1x2 is 5Gbit, two lanes, so 10Gbit. Gen 2x1 is 10Gbit, one lane. Gen 2x2 is 10Gbit two lanes, so 20Gbit."
The fact you got all that into a 13 minute video was pretty impressive. I think it could have stretched to 30 minutes or more. Thanks for putting this out there, it will certainly be helpful when I'm looking for cables for my devices.
Well, at least the USB Implementers Forum stopped putting things like "Full Speed" or "High Speed" in the names. It's not much, but it's something. If they would now stop renaming older specifications every few years, that would be nice.
They don't rename older specifications. It's just the new revision INCLUDES the features and speed modes of the older ones, because of course, they have to be compatible.
@GaryExplains Do you mind explaining more about USB 3.2 Gen 2x1 and USB 3.2 Gen 1x2? Like How do they differ from each other, and what are the advantages of getting one over the other?
Crazy! Names like 3.2 Gen 2x1, x2, etc. is way too detailed to be understood. Names should be simple (ie USB 1, 2, 3, 4, 5, etc.) so general consumers don't have to get caught in the weeds. If someone needs to know the specific details they can always Google it. As we progress this is only going to get worse.
Always 🤣 I used to attend the quarterly sales meetings from an old tech firm that I worked for back in the 90’s. Trying to get them to understand that on a modem (woohoo) V.22 vs V.22bis was double the speed @double the cost because every recent order that had come in was for the new tech V.22bis modems using the older prices. I told them to stick to the actual baud rate, which they all knew. Us ‘techies’ would worry about the actual part numbers V.22 numbers etc.
I remember the days of Firewire (IEEE 1394a) and how I loved the ability to chain devices over USB's master/slave roles. I thought it would win out, but now it leaves me a drive sitting idly by as a historical landmark. Other issues in that day were trying to find even faster storage solutions and looking early at networked storage over Firewire 400 and 800 hard drives so that we could edit and move scratch disks for Final Cut Pro, after all gigabit Ethernet was the fastest thing I could see then to transfer video data at the time. So much has changed, but thinking through different protocols, encoding, and that overhead made for interesting hardware choices back then. Glad things are more settled now. Or are they?
I think there's a bug in the bandwidth chart you used. usb 1.x was 1.5Mbit and 12Mbit for Fullspeed. so the chart should actualky show 0.012 Gbit and not 0.12
Hi, Gary. So when Apple says the iPhone 15 Pro uses USB 3 with data transfer speeds of 10 gbs, which USB protocol is it actually using? And how is it different from the USB in the regular iPhone 15? Please explain! Thanks.
Late reply but it would either be 3.1 Gen 2 or 3.2 Gen 2 (I'd just call it 3.1 without the Gen bullshit). The regular on the other hand just uses the old USB 2.0 standard.
I'm mostly baffled how slow USB-C adoption is so slow, companies slacking so much. Also lack of USB4 ports even on expensive boards and lack of devices still.
question? usb 3.2 vs usb c 3.2 gen 2 on my pc and i bought a external ssd with a usb c to usb b(into pc) it was also some one who told me to buy a usb c to usb c 20gbps cable instead of the cable that was in same box as my external ssd(I did this and just connected it to my pc) So the transfer speeds of 400mb/s went up to 687mb/s so it was definatly faster....This i could see without a doubt myself.. But my question is this because i game from my external ssd and loading times has been good will the loading times be even faster now after i got this usb c to c 3.2 gen 2 cable(or is it no differences when it comes to games loading times and only faster when i transfer big game files between my nvme to external ssd"this i saw at once,but loading times w games i dont kno??9 Also why did my external ssd come with a slower usb c to b cable and not the faster? kingston xs1000 2tb is the name if anybody knows this because its just sad to if they dont ship the faster cable and just the older n slower instead(Is this because there are not enough people using usb c ports on pc or what could be the reason to this??) Thanks n must say this was a great video(i have never been aware of all the different speeds(i knew about usb2.0 and usb3.0 and that was it)
Can anyone imagine a world where USB never really took off? Would firewire have developed into what USB is today? Would external drives use eSATA? Would printers use turbocharged parallel ports? Would mice and keyboards still be using the 6-pin PS/2 style interface? Would phones still use barrel jacks to charge? We would be in a VERY different world if USB hadn't caught on.
What a bloody mess. It seems variety is the spice of life that gives you the toilet runs and mouth blisters at once, all while not requiring the ingestion of any food. $0.02
and if your doing a pc build only intel has this usb-4.0 , ..... me wanting to do a small build with a monitor on the side and only want 1 cable to it , this won't happen me being a AMD Guy ? .... Right ?
As far as I know, AMD has support for USB 4 since 2022. A quick search for "amd usb 4" reveals lots of info. Why do you think it is Intel only? This is USB, an international standard. USB 4.0 is even on Apple Silicon (based on Arm and nothing to do with Intel).
@@GaryExplains I don't see any USB 4.0 thunderbolt on AMD motherboards only Intel , I'm doing a AMD build right now that has USB 3.2 Gen 2x2 20Gbps Type-C port can this output video through this cable ? or will I have to use HDMI ?
A quick google search for "amd motherboard with USB 4" gave me this www.tomshardware.com/pc-components/motherboards/msi-x870e-carbon-wifi-motherboard-review I didn't bother searching any further.
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. ).
USB is backwards compatible so you can connect a USB 3.0 drive into a MacBook Air. However if your drive has a type A connection (which I guess it does) then you will need a USB Type A to USB-C adapter. Apple has one and there are many third party ones.
@@GaryExplains thank you so much!!!! I plug my hard drive into my current MacBook via a 3.0 usb cable . Can I just put that into the 3.1 gen 2 port of the MacBook Air?
The MacBook Air only has USB-C ports. So, as I said, if your drive has a type A connection (which I guess it does) then you will need a USB Type A to USB-C adapter. Apple has one for sale and there are many third party ones.
Don't confuse the connector type and the relevant USB standard. Some USB 3.x ports can be USB type A or USB-C (depending on the revision and/or generation). The MacBook Air has USB-C ports.
The annoying bit is that you can’t physically tell the difference between a $10 Amazon Basics cable for charging your phone and a $150 I bought this Thunderbolt 4 special at the Apple Store
All this basically the same data transfer rates but renamed & x1, x2's are confusing, why not call them USB Pro, USB Max & USB Ultra like smartphones & then add gen 1, gen 2 etc.... I often missed out on a newer generation of USB versions because retailers doesn't infirm customers trying to clear old stock.
Yes fine! I think! But the Chinese sellers of addon bits and bobs will call whatever they sell whatever they want again. Thus confusing confusion even more, so the seller confusion of Aliexpress terminology and naming flows to ebay and Amazon as the sellers look for new selling platforms. And no. Confusion of confusion does not mean it is all corrected. Two wrongs still do not make a right.
Yeah... USB's naming convention is like throwing perfume on a pile of hot garbage in a hot and humid summer day to see if it "fixes" the whole thing. It's one of the most insanely idiotic naming conventions I've ever heard. The problem isn't only about understanding what it is, it's about identifying what devices have what - which manufacturers conveniently won't list or tell, btw - then testing a whole combination of ports and cables to see what works and what doesn't because of a standard that cannot work as a standard, and then after you went through all that multiple times over, you have to keep managing all those devices and cables that you don't know exactly what will work and what won't because of this entire mess. And then to further make things worse, now we're dealing with enough power to fry devices and potentially even cause fires. Between USB 1 and 2 you didn't really have much of a problem because even if stuff was poorly made, because it was low powered, things just wouldn't work and that was it. Now, if you have a poorly made USB-C cable or out of spec device, you could fry something up, as happened early on. You pick any random USB A to USB C cable laying around, you have no way of telling it it's a USB 2 power only cable, all the way up to the latest USB 4 spec with full support. It's just a total shitshow. Anyways, rant over, let me give a tip for people with this problem... go to Amazon, Aliexpress or other platforms and search for "USB cable tester", look for a bare circuit board device with multiple connectors. Some will have 6 different connector types, some will have 9 - between USB-C, USB A, micro USB, and then perhaps it could have USB B, micro B, mini B and whatnot. And then a bunch of leds in the middle of the board. You just plug cables from one side to another and the led indicators will tell you what the cable supports. It's a life saver.
The USB naming committee is to be renamed the "Universally Stupid Board of confusement and fuckery" or USBcf 1x2 Gen 3.2 version 1 - revised edition...fast 22.5 Gbps ....AAAHHHRAAHAHHH!!!
Instead of naming USB 3 using confusing terms, why not just name USB 3 based on their speed? For example... USB 3 5Gb/s USB 3 10Gb/s (single lane) USB 3 10Gb/s (dual lane) USB 3 20Gb/s This would be WAY more simple. (oh great, now I need to patent this) 😁
Well obviously file transfer speed is determined by the speed of the disk drive. If it was a mechanical HDD from 2008 then there is no way it would match those speeds. The drive is the bottleneck not the data path.
I SUPPOSE THE NEED IS FOR FASTER SPEEDS AND TO KEEP THE MONEY COMING IN. IT USED TO BE A SIMPLE PLUG-AND-PLAY DUE TO GOOD PROGRAMMING. NOT ANYMORE ITS JUST ONE RIDDLE AFTER ANOTHER. WE ARE GETTING PIS-T OFF
Apple also helped develop various things for Thunderbolt like the minidisplay port it was using from the beginning on Macs. But it is primarily Intel that develops it and I think has full ownership of it (at least the later versions). Apple applied for the trademark but gave it to Intel. I dunno if Apple has lost some ownership since they started to make their own CPUs for Macs instead of using Intels.
Perpetuating "USB 4.0" or "USB 4" is harmful to consumers because not only does it go against the original material, but it is also worse for SEO and creates confusion. There's a reason it's USB4 , the marketing is clearer and avoids nonsensical questions like "what is USB 4.0 v2.0" ???"
Changing the naming scheme yet again, is just confusing. USB 4.0 gen 2 would have been more consistent. The point is that the USB-IF promoted a naming scheme with a ".x" part and now it wants to change that and expects that those decades of branding will just be forgotten. The problem is the USB-IF perpetuating USB4, not the other way around. USB4 Version 2.0 isn't remotely consistent. But when has the USB-IF been consistent?
@@GaryExplains Love what you do Gary! I'm pretty technical, but on the USB front I've mostly trusted that the USB interfaces found on most devices are chosen to be as compatible as possible for most users. At least in my circumstances, that's worked fine.
Yes, but if you wanted to buy some external storage or direct attached storage with RAID then knowing the USB capabilities of the device and of the host is important, don't you think?
Sorry, I don't understand. What has the naming got to do with the actual USB tech, the speed, the power/charging, the ports, the cables? What don't you like about USB that it needs to be replaced? What standard would you prefer?
What I can't figure out is... Do I need to throw away my so called fast / universal / High Speed 3.0 chargers or will they still work with the new devices with 3.2 ports. I don't really care if they charge slowly and may not keep up with power consumption. I would like to change out my charging stations over time rather than a big investment all at once.
Brilliant suggestion 🤪 A couple of problems... a) What if the computer you have doesn't support USB 4? b) What if the peripherals you have or a new one you want to buy isn't available in USB 4? What then?
So what you’re saying is that the primary purpose of the naming is to be as confusing or ridiculous as possible.
Pretty much yeah 🤦🏽
The USB 3.2 and later naming makes sense though but the way they RENAME older versions is indeed gonna cause confusion
Don't worry man, they are going to change it again anyway.
If the USB-IF had an ounce of common sense, they would drop all the "3.1" and "3.2" and "Gen" business. Just make it "USB 3 5x1" for the original and "10x1", "5x2" and "10x2" for the rest.

Beware of Thunderbolt 3 cables that DO NOT support Displayport. I bought Belking TB3 2M Active and discovered it doesnt support Displayport
Instead of naming USB 3 using confusing terms, why not just name USB 3 based on their speed?

I SUPPOSE THE NEED IS FOR FASTER SPEEDS AND TO KEEP THE MONEY COMING IN. IT USED TO BE A SIMPLE PLUG-AND-PLAY DUE TO GOOD PROGRAMMING. NOT ANYMORE ITS JUST ONE RIDDLE AFTER ANOTHER. WE ARE GETTING PIS-T OFF
That's a OnePlus USB cable and they kept using USB2.0 for years.
You lost me at 'let me explain' but good video as always
😂 I didn't actually say that in this video!
@@GaryExplains really? Guess I just assumed you did. I even hear it in my dreams 😂
Thanks professor!
Apple also helped develop various things for Thunderbolt like the minidisplay port it was using from the beginning on Macs. But it is primarily Intel that develops it and I think has full ownership of it (at least the later versions). Apple applied for the trademark but gave it to Intel. I dunno if Apple has lost some ownership since they started to make their own CPUs for Macs instead of using Intels.
As clear as mud!
Don't get confused… Just remember USB is USB…
🤦♂️
Nice video
Thanks
*What a mess lol*
Go home, usb-if, you're drunk
Gj as usual ❤
So maybe I have multiple USB in the same physical male type-c 😂
the usb 3.2 is really confusing.
meh . . . I think I'll wait for USB 6.66 PhD DDS AM/FM eXtreme!!!
You missed the "pro max" out!
Perpetuating "USB 4.0" or "USB 4" is harmful to consumers because not only does it go against the original material, but it is also worse for SEO and creates confusion.
There's a reason it's USB4 , the marketing is clearer and avoids nonsensical questions like "what is USB 4.0 v2.0" ???"
But USB4 Version 2.0, as specified by the USB-IF, is OK? 🤷♂️
My keyboard corrected my intentional mistake, I meant to write the mistake "USB 4" not USB4
Changing the naming scheme yet again, is just confusing. USB 4.0 gen 2 would have been more consistent. The point is that the USB-IF promoted a naming scheme with a ".x" part and now it wants to change that and expects that those decades of branding will just be forgotten. The problem is the USB-IF perpetuating USB4, not the other way around. USB4 Version 2.0 isn't remotely consistent. But when has the USB-IF been consistent?
OMG! Chaos!
If the USB 3 naming comity is watching, I have a simpler solution.
USB 3 5Gbps
USB 3 10Gbps
USB 3 20Gbps
Problem solved.
So basically 😅 usb 3.0 😅 is non-existent
USB-A or USB-C? Either way both exist
@@someoneyouneverknow7529 USB C can't be 3.0.
Omg. Are they crazy?
i propose future dev of the old firewire and the 1st would be called DragonFireWire 1.0 which has a speed of 50 Gbit/s! u know nothing nerd snow!
In one ear, out the other...
Sounds painful 😜
@@GaryExplains Love what you do Gary! I'm pretty technical, but on the USB front I've mostly trusted that the USB interfaces found on most devices are chosen to be as compatible as possible for most users. At least in my circumstances, that's worked fine.
Yes, but if you wanted to buy some external storage or direct attached storage with RAID then knowing the USB capabilities of the device and of the host is important, don't you think?
@@GaryExplains For sure; I'd want to do my research before doing that kind of setup and I'd trust your video as a resource.
👍👍
Clear as MUD ;)
🎉
USB needs to be replaced.
Really, why? What with?
@@GaryExplains The USB-IF keeps changing the names of everything.
I know that, a large part of the video is about that. But why does that mean that USB needs to be replaced? I don't understand.
@@GaryExplains We need a standards body that does not constantly change the names of old versions of the standard.
Sorry, I don't understand. What has the naming got to do with the actual USB tech, the speed, the power/charging, the ports, the cables? What don't you like about USB that it needs to be replaced? What standard would you prefer?
What I can't figure out is... Do I need to throw away my so called fast / universal / High Speed 3.0 chargers or will they still work with the new devices with 3.2 ports. I don't really care if they charge slowly and may not keep up with power consumption. I would like to change out my charging stations over time rather than a big investment all at once.
I didn't really cover charging, but the chargers are always backwards compatible, just slower, as you said.
@@GaryExplains Great! Thank you very much.
Just use usb4
Brilliant suggestion 🤪 A couple of problems... a) What if the computer you have doesn't support USB 4? b) What if the peripherals you have or a new one you want to buy isn't available in USB 4? What then?
