New USB 3.2 with double bandwidth. USB 3.2 Double speed on laptops

In the foreseeable future, new external hard drives and pendrives will be available to trade data twice as fast. Provided we can understand which cable to buy.

Is the better enemy of the good? This is partly the case with the new version of the USB standard, which is simply referred to as 3.2. In some cases, we can almost double the data bandwidth. Copying data from a USB storage device that complies with this standard would be almost twice as fast.

USB 3.2 is backwards compatible. That means we can handle it easily. Simply transmitted data is provided by the older version of the standard.

USB 3.2 Double speed on laptops How fast is USB 3.2?
The following values are theoretical. The actual data transfer speed depends on the theoretical and predicted bandwidth, the current CPU usage, the file system used, and more. Copy under ideal conditions

Once again: in optimistic laboratory conditions. Even if these are theoretical values, they still make an impression. We just have more problems than we should.

USB 3.2 covers the USB 3.1 standard, so there are several minor versions. Good luck buying cables in the store.
USB 3.0 is a standard with 5 Gbps bandwidth. Compatible cables are labeled as SuperSpeed USB. Then, however, USB 3.1 Gen 1 appeared, the ... same speed and USB 3.1 Gen 2, which provided a speed of 10 Gb / s. It's worth noting that USB 3.1 Gen 1 is exactly the same as USB 3.0 - only the name has been changed. You follow? We continue to fly.

USB 3.2 Gen 1 provides a 5 Gb / s transmission (the same as USB 3.1 Gen 1 like USB 3.0), USB 3.2 Gen 2 a 10 Gb / s transmission (the same as USB Gen 2), while USB 3.2 Gen 2 × 2 Consumer Name is SuperSpeed USB 20 Gbps - offers a transfer rate of 20 Gbps.

Remember now that the stores are still in stock, which will be on the market for some time. This means that they look different and are marked as follows:

USB 3.0,
SuperSpeed USB,
USB 3.1,
USB 3.1 Gen 1,
USB 3.1 Gen 2,
USB 3.2,
USB 3.2 Gen 1,
USB 3.2 Gen 2,
USB 3.2 Gen 2 × 2,
SuperSpeed USB 20 Gbps.
I do not count here USB 2 (High Speed) and USB 1.1 (Full Speed). I wish you good luck in the store to get around in all this. Because the already complicated marking system did not have to be simplified at all.

I do not know who works on USB-IF, the group responsible for USB standardization. Surely nobody would buy a USB cable from an electrician. It is a duty that we have to remember the specification of such an element that we want to connect to an external hard drive. Of course, accessory manufacturers benefit from this mess by using additional, misleading terms to sell as little as possible
