It is backward-compatible with USB 2.0, and can deliver up to 5 V(1.8 A) of power. USB 3.0 was released in 2008 and has a top speed of 5Gbps in SuperSpeed mode and is typically colored blue. It is backward-compatible with USB 1.1 and has a maximum output power of 2.5 V(1.8 A). Released in 2000, USB 2.0 has a maximum speed of 480Mbps in Hi-Speed mode, or 12Mbps. In many cases, USB 1.1 only performs at 1.2Mbps and it has grown largely obsolete.

USB 1.1 was the first USB version released in 1998 and has a top speed of 12Mbps. Versions of the USB include 1.1, 2.0, 3.0, and 3.1.

The USB Type refers to the physical shape and wiring of the ports and plugs, while the version denotes the speed and functionality of the full interconnection system. Every 3.1 port is backward compatible with 2.0 connectors.In order to fully understand USB Type-C, Type-A, and Type-B, we must first look at the various versions of the USB standard. We are seeing its rise in the laptop area so hopefully, more desktop motherboards will come out with this port. Sadly, this is still taking its time to come to the mainstream market. This is an impressive performance from a USB port considering most SATA SSDs can’t even utilize that speed to its maximum. The transfer speed roughly translates to 10 Gigabits/s (1.25GB/s or 1250MB/s). USB 3.1 Gen2 is twice as fast as USB 3.0 and 3.1 Gen1. With that out of the way, let’s talk about Gen2. So, if you ever see a Gen1 port don’t get misguided as if its faster than USB 3.0. Same rate of transfer, power delivery, everything. USB 3.0 and 3.1 Gen1 are both exactly the same ports. First off let’s get some confusion out of the way. It was announced alongside the new Type-C form factor.

USB 3.1 started making its appearance all the way back in January of 2013. USB 3.1 (Gen1 and Gen2) Image: logicsupply USB-C also supports Thunderbolt 3 which we’ll discuss later on. Imagine a future where you just need one cable for all your devices. The main advantage here is that it is reversible and tiny so it can be used in nearly every device. USB-C is a new form factor that is an oval-shaped reversible connector, meaning it can be plugged in either way. Since then, we’ve seen USB-C ports rise up in popularity. They made a bold move of removing all USB-A ports with a single USB-C port in their new Macbook redesign. The USB-C port has been around for a while now, yet was popularized recently in 2015 by Apple. It’s the port we are all used to in our everyday lives. It’s been an industry standard for decades in computers and other devices. It’s the simple non-reversible rectangular port which we use to plug in everything from mice to speakers. Type-A is the port we are all familiar with. To make things simpler for us and the readers, we’ll be concerning ourselves with just the two important ones for PCs. Of course, these can be further broken down into even more ports such as micro-A or micro-B (typically used in phones). There are tonnes of different USB form factors out there. Sadly, Thunderbolt 3 is still a rarity and taking its time to come to the mainstream market.
#USB 1 VS USB 2 VS USB 3 MOVIE#
You can transfer a full 4k movie in under a minute. Even in simple transferring of data, it’s impressive. What can you do with that blazing speed? You can use it to connect an external graphics card, a 4k display and even charge your laptop. Thunderbolt 3 is four times faster than USB 3.1 Gen2 maxing out at a whopping 40 gigabits/s (5GB/s or 5000MB/s). It’s aptly called the one port to connect them all.

Thunderbolt 3 is a protocol, not a port so it’s often seen that a USB-C port with Gen2 support also works with Thunderbolt 3. There are obviously limitations to this with wattage alongside with power delivery. Now, each of these protocols has bi-directional power delivery meaning any of them can be used to charge a laptop or power a display. It can utilize USB 3.1 Gen1 and Gen2 alongside thunderbolt 3. Just another topic we want to quickly get out of the way is Thunderbolt 3.
