How Much Power Do USB 3.2 and USB 3.1 Offer? In a quick search of Amazon, we found an M.2 NVMe USB 3.2 Gen 2x2 enclosure for $68 and USB 3.2 Gen 2 enclosure for just $28. The fastest external SSDs or SSD enclosures can operate at USB 3.2 Gen 2 (10 Gbps) or USB 3.2 Gen 2x2 (20 Gbps), though the 10 Gbps speed is far more common and cheaper. Monitors or docking stations that use DisplayLink technology, which allows your computer to output video over a standard USB Type-A port, often require 5 Gbps speeds.įinally, and perhaps most importantly, external SSDs and the best hard drives need at least USB 3.2 / 3.1 / 3.0 speeds. So, if you have a mouse, a keyboard and a webcam all plugged into the same hub, they will definitely need at least the 5 Gbps that USB 3.2 Gen 1 / USB 3.1 Gen 1 provides. If you're using a USB hub, you'll want at least a 5 Gbps connection, because all of the peripherals connected to that hub will be sharing that bandwidth. However, some of the best webcams, require USB 3.2 / 3.1 / 3.0 connectivity, especially when they're delivering 30 fps at 2K or 4K resolutions. Wired mice and keyboards, even those with high polling rates, don't even max out the USB 2.0's 480 Mbps limit. USB 3.2 Gen 1 and USB 3.1 Gen 1 run at up to 5 Gbps speeds, which in and of itself, is more than most peripherals require on their own. If you want to get 20 Gbps speeds, all three pieces: the port, the peripheral and the cable, must support that speed. If you have a USB 3.2 Gen 2 port and want to take advantage of its 10 Gbps speed, look for a cable that supports 10 Gbps (it could be USB 3.2 Gen 2 or USB 3.1 Gen 2) and a peripheral that does the same. So, if you use a USB 2.0 device or cable and plug it into a USB 3.2 port, you'll get a connection but at the speed of the slowest link in the chain (in this case 480 Mbps). What Kind of Connectors Do USB 3.2 and USB 3.1 Use?Īs with all things USB, USB 3.2 and USB 3.1 are backward compatible with older USB standards. That shouldn't matter to you as an end user, but you may see the USB 3.2 Gen 1x2 terminology. The difference is that, while USB 3.2 Gen 2 has a single, 10 Gbps data lane, USB 3.2 Gen 1x2 uses two 5 Gbps lanes to get to its 10 Gbps total. There's also a lesser-used version called USB 3.2 Gen 1x2, which is 10 Gbps and nearly identical to USB 3.2 Gen 2. Would it have been less confusing if they called it USB 3.2 Gen 3? Who knows? The 20 Gbps speed is called USB 3.2 Gen 2x2, because it uses two 10 Gbps lanes to give you the 20 Gbps speed. In honor of the new speed, the version number changed for all speeds so the 5 Gbps speed became USB 3.2 Gen 1 and the 10 Gbps speed became USB 3.2 Gen 2 and the 20 Gbps speed became USB 3.2 Gen 2x2. In 2017, the organization rolled out a 20 Gbps speed for USB 3.x devices. So USB 3.0 (5 Gbps) became USB 3.1 Gen 1 and the new, 10 Gbps speed became USB 3.1 Gen 2. In 2013, USB-IF announced that it was taking USB up to 10 Gbps and, in doing so, changed the version number for all USB 3.x products. Many peripherals don't even need to go beyond USB 2.0. In fact, even today, the vast majority of USB ports and products don't go beyond 5 Gbps nor do you need them to. In 2008, the USB 3.0 standard launched, bringing USB up to 5 Gbps, a huge leap from the 480 Mbps speed of USB 2.0, and for many years that was as fast as USB could go. The different USB 3.x version numbers exist purely because the number has been iterated with each speed advancement. The spec sheets may not even list a generation number, though if they don't, you should assume that it's Gen 1 (5 Gbps).
