Deciding between USB 3.1 or USB 3.2 depends on what you need and your budget. Users can determine the data speed they need by understanding the various types of USB ports and their data transfer speeds. This knowledge can helps you easily find storage products that meet your requirements.

Difference between USB 3.1 Gen 1, Gen 2 and USB 3.2

Here's the difference between USB 3.1 Gen 1, Gen 2 and USB 3.2:

  1. USB 3.1 Gen 1: Also known as "SuperSpeed USB," this version offers data transfer rates of up to 5 Gbps (gigabits per second). It is backward compatible with USB 2.0, meaning you can connect USB 2.0 devices to a USB 3.1 Gen 1 port.
  1. USB 3.1 Gen 2: Also called "SuperSpeed USB 10 Gbps," this version provides double the data transfer speed compared to USB 3.1 Gen 1. It offers data transfer rates of up to 10 Gbps. Similar to USB 3.1 Gen 1, it is backward compatible with USB 2.0 and USB 3.1 Gen 1 devices.
  1. USB 3.2: This is the latest version of the USB standard and introduces even higher data transfer speeds.

USB 3.2 Gen 1x1 offers the same 5 Gbps speed as USB 3.1 Gen 1.

USB 3.2 Gen 2x1 (previously known as USB 3.1 Gen 2) provides the same 10 Gbps speed as USB 3.1 Gen 2.

USB 3.2 Gen 2x2 (previously known as USB 3.2 Gen 2x2) offers double the speed of Gen 2, providing up to 20 Gbps data transfer rates. 

The advancer USB technology can provide products with faster data transfer speeds.

Advantage of DIY NAS equipped with USB 3.2

The advantage of a DIY NAS equipped with USB 3.2 is the increased data transfer speed and improved performance compared to previous USB versions. USB 3.2 provides faster data transmission, with theoretical speeds of up to 20 Gbps. So the DIY NAS equipped with USB3.2 can transfer data much faster, resulting in quicker file transfers and improved overall system responsiveness.
