What Is an SS USB Port?

There has been a lot of changes since the invention of Flashdrives or USB ports. USB is also known as Universal Serial Bus. A SS USB port stands for SuperSpeed Universal Serial Bus, where the speed has been increased to 625MBPS. And with great speeds comes great features.

SS USB is also known as USB 3.0, and as the name suggests, it is the third version of USB. Further, SS USB adds to the speed and many other features. If you want to know them, stick to this guide. SS USB is likely ten times faster than the standard USB 2.0. Moreover, you must have seen that SS USB ports are often colored in Blue are present in most modern laptops and PC.

They are colored to distinguish between the 2.0 and the 3.0 ports. Interestingly, USB 3.1 was released in 2013, but before that, only 3.0 was known. And USB 3.1 keeps everything preserved, except the speed was drastically increased to 1250MBPS. This means the speed was doubled, and it is known as SS+ USB.

The SS USB or USB 3.0 is similar to USB 2.0 but with many improvements and alternative implementations. Earlier USBs were based on four concepts that include bulk, control, isochronous, and interrupt are preserved, and the protocol of the electrical interface is different. 

These specifications differentiate SS USB from other USB versions, making it more exciting than the other ones. Moving forward, let’s talk about the features of SS USB.

  • Transfer Speed: SS USB or USB 3.0 added a new transfer type called SuperSpeed that is 5GBPS. Electrically it is similar to PCI Express 2,0 and SATA 2.0. 
  • Increased Bandwidth: There are two unidirectional data paths used by SS USB that increases the bandwidth. This makes it different from other USB Devices and makes it faster in comparison. Also, one to receive data and the other to transmit data is used. 
  • Power Management: U0 and U3 link power management is used in most SS USB ports. This means, even if you switch off your laptop or PC, you can still use the port as a power adapter to charge other devices. This makes it even more useful in journeys. 
  • Improved BUS Use: There is a new feature in SS USB that is the use of NRDY and ERDY that lets a device asynchronously notify the host about its readiness without any waking up procedure. Whenever you plugin a new flash drive in a USB port, you might have noticed an autoplay dialog box. That’s what we are talking about. 
  • Rotating Media Support: This bulk media protocol is updated with a new feature called streaming protocol. It allows a large number of logical streams to meet an endpoint. 

Conclusion

SS USB or USB 3.0 or SuperSpeed USB is a new version of USB with a fast transfer speed of 625MBPS. Further, it supports duplex architecture, and on the other hand, USB 2.0 supports only half-duplex. This duplex a clear-cut upper hand over the other USB Ports. Moreover, it has a lot of other features that the previous versions didn’t have.
