Updating usb 1 to usb 2
The purpose of this simple article is to inform you of different USB types, different generations, and how to add in USB more ports to your PC.
So should you care about transfer speeds and power delivery throughout different generations? If you rarely connect external drives for transferring data, you can still get by with USB 2.0 for connecting your external devices.
These types of USB are distinguishable by their blue colored inserts and usually equipped with a 3.0 logo. Don’t worry you don’t have to swap out your motherboard entirely just for one port.
USB 3.0 is miles ahead of 2.0 maxing out at almost 5 megabits/s (625MB/s) which is over 10 times faster. Simply pick up a PCIe USB adapter for your board and enjoy the versatility of Type-C or the speeds of USB 3.1.
The transfer rate is extremely slow, maxing out at 480 megabits/s (60MB/s).
Of course, this is a bit slow for data transfer but for connecting peripherals such as keyboards, mice or headsets, the speed is sufficient.
Sadly, this is still taking its time to come to the mainstream market.
Imagine a future where you just need one cable for all your devices. USB-C also supports Thunderbolt 3 which we’ll discuss later on.
Just another topic we want to quickly get out of the way is Thunderbolt 3. It can utilize USB 3.1 Gen1 and Gen2 alongside thunderbolt 3.
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.
Every 3.1 port is backward compatible with 2.0 connectors.
USB 2.0 is the most common version of the USB standard we use every day.
There are obviously limitations to this with wattage alongside with power delivery. 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.
