Does USB 3.0 require a special cable?

USB 3.0 is a standard, delivered in November 2008. Most new PCs and gadgets being produced today uphold this norm, which is regularly alluded to as SuperSpeed USB. SuperSpeed (USB 3.0) is upheld simply by USB 3.0 and more current interfaces and requires a connector and link with additional pins and wires, normally recognizable by the blue supplements in connectors. To get USB 3.0 paces, you need extraordinary USB 3.0 cables. Indeed, USB 3.0 cables are unique. Even though you can interface a USB 3.0 gadget through a USB 2.0 link, to accomplish full USB 3.0 paces, you need to rework any current cabling. USB 3.0 links have more inner wires, are typically blue, and are observably thicker than the old USB 2.0 links. You can’t accomplish USB 3.0 velocities without a USB 3.0 cable. In any case, speed isn’t the main issue. A USB 2.0 link will work (at USB 2.0 rates) for a few, however not all, USB 3.0 gadgets. There are in any event, three significant contrasts in link development between the two guidelines. Identified with Speed:

USB 3.0 cables have nine inside conductors versus four in USB 2.0 links.

Four of the nine inside conductors coordinate the USB 2.0 setup (two are for force and two are for signal). Associating a USB 3.0 gadget with a USB 2.0 link utilizes those conductors and works as a USB 2.0 gadget. The other five are signal conductors utilized for the specialized technique that gives USB 3.0 super speed. A decent broad portrayal can be found here: USB 3.0.

USB C Cables

  • USB 3.0 links have a restriction of three meters versus the USB 2.0 constraint of five meters. The link can be any length as long as it meets the entirety of the particular electrical necessities. The 10 ft USB C cable depends on the most extreme permissible misfortunes utilizing the biggest suggested wire size to adapt the link.

Identified with Force

A USB 2.0 link may not be sufficient for a high current USB 3.0 gadget.

Some USB 3.0 gadgets draw more force than USB 2.0 gadgets. The force conductors in USB 3.0 links should have the option to convey 900 Mama versus 500 Mama for USB 2.0 links. USB 3.0 links are unique. Although you can associate a USB 3.0 gadget through a USB 2.0 link, to accomplish full USB 3.0 velocities, you need to re-wire any current cabling. USB 3.0 links are commonly thicker because they have nine inward wires versus four on USB 2.0 links. USB 3.0 connectors are additionally indicated to have blue supplements. We sorted this out in the most difficult way possible during the USB streak drive bunch test.


USB 3.0 is the most recent update of the General Sequential Transport standard delivered in 2008. This new standard offers expanded exchange rates up to 4.8Gbps, expanded most extreme transport power, improved force the executives, and new connectors and links that encourage the higher exchange speeds and extra force. Usage of the innovation started in 2009 at first with USB 3.0 connectors (PCIe and Express Card) to establish the new 3.0 ports into current PC frameworks. Centres followed, permitting extra 3.0 development. PCs and workstations have gradually been executing the new norm since 2010, yet the new 3.0 ports are relied upon to be in most new PCs by 2012 when the well-known producers make it a norm.

USB 3.0 cables and gadgets are additionally needed to accomplish the quick USB 3.0 exchange speeds. Presently most 3.0 gadgets incorporate outer hard drives, hard drive docks and blaze drives. Extra gadgets like memory card perusers, show connectors, and move links were dispatched in 2011, with more items expected in 2012 and later.

What is the contrast between USB 2.0 and USB 3.0?

When looking at 2.0 and 3.0, there are a couple of significant contrasts. First, the exchange rates: USB 2.0 offers move paces of 480 Mbps and USB 3.0 offers move paces of 4.8 Gbps – that is multiple times quicker. Note that the exchange speeds likewise rely upon the gadget being used to stand the transport type and USB ports and links.

The second primary distinction is expanding another actual transport – multiplying the number of wires from 4 to 8. Extra wires require more space in both the links and connectors, so new kinds of connectors are for the B Male and Miniature B Male. These connector types are bigger than the 2.0 counterparts to oblige the extra wires and can’t be utilized with 2.0 ports.

What are the contrasts between USB 2.0 links and USB 3.0 cables?

USB 3.0 links also have various connectors (commonly blue within), as shown in the picture beneath close by the 2.0 partner connectors. This implies that any gadget that utilizes the various connectors can’t utilize the 2.0 identical links. Furthermore, while the 2.0 B connectors actually fit into the 3.0 B ports, the diverse wiring arrangement doesn’t permit appropriate information move. The A connectors actually work appropriately, so any 2.0 gadget with a 2.0 link can be utilized with 3.0 ports or center points.

To summarize:

  •  USB 3.0 gadgets require 3.0 links
  • USB 3.0 links can be utilized with 2.0 gadgets and ports if the connector types fit (no B Male or B Miniature connectors); however, the exchange rate will fall back to 2.0
  • USB 2.0 links can be utilized with 3.0 ports, yet the exchange rate will fall back to 2.0

What do you need to get the greatest throughput on a gadget?

To accomplish the full USB 3.0 Super Speeds (4.8 Gbps), the accompanying things are required:

  •  A USB 3.0 port in the PC or PC (inbuilt USB 3.0 port OR connector with 3.0 ports introduced in PCIe 2.0/2.1 or EC 2.0 openings)
  • A USB 3.0 link that associates the outer USB 3.0 gadget to the 3.0 port, which is normally furnished with the 3.0 gadget
  • A gadget that upholds USB 3.0 like a hard drive, card peruser, or a camera.
