Most PC manufacturers label each USB port using the logo for USB type ... the USB 2.0 logo is a trident, while the USB 3.0 logo is a similar trident with the letters 'SS' (which stands for SuperSpeed) attached. As we mentioned at the outset, USB 4 is based on the Thunderbolt protocol which Intel made freely available to the USB Promoter Group (which it’s a member of, along with many other tech giants), allowing USB 4 to offer Thunderbolt 3 equivalent speeds of 40Gbps; twice that of the preceding USB 3.2 Gen 2x2 standard.

Having two Gen 2x2 devices in hand, we felt that the standard was gaining market traction. To get started with the review, we reached out to a couple of the aforementioned expansion card manufacturers, and Yottamaster was the first to respond with a retail sample of the C5 expansion card. We can only hope that happens soon. Because Micron (Crucial), Samsung, and SanDisk are all trying to defy economic gravity with recent launches, there is only one likely outcome.

In the scope of Gen 2x2 drives, the T9 is up there with the best options and is comparable with the performance we’ve seen from the Crucial X10 Pro and Kingston XS2000. The USB Implementors Forums (USB-IF) maintains USB specifications and compliance, and it's behind the naming schemes found on USB cables and devices. When it introduced USB 3.1, rather than keep things simple and let that name differentiate from USB 3.0, it called the new standard "USB 3.1 Gen 2." USB 3.0 was retroactively renamed "USB 3.1 Gen 1."

Unfortunately, you usually cannot tell if a laptop’s USB-C port can deliver video just from looking at it. You’ll need to read the computer’s instruction manual or spec sheet or you could just experiment. First Certified Superspeed USB Consumer Products Announced" (PDF) (Press release). USB Implementers Forum. 5 January 2010. Archived from the original (PDF) on 14 January 2010. There are other nuances to bear in mind, such as the fact that SuperSpeed USB 20Gbps (USB 3.2 Gen 2x2) requires a USB Type-C connector (the previous incarnations don’t), but let’s not get too wrapped up in the old standards here.

Unlike previous standards, the USB3.0 standard does not specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires, the maximum practical length is 3 meters (10ft). [13] Power and charging [ edit ] The "SuperSpeed" bus provides for a transfer mode at a nominal rate of 5.0Gbit/s, in addition to the three existing transfer modes. Accounting for the encoding overhead, the raw data throughput is 4Gbit/s, and the specification considers it reasonable to achieve 3.2Gbit/s (400MB/s) or more in practice.

Technically speaking, neither USB 3.2 nor USB 3.1 by itself can deliver video. Using DisplayLink technology, one can convert and compress video into USB data that goes out to a specially-enabled hub or portable monitor. However, few people today use DisplayLink devices.

Mini USB first appeared at the turn of the century alongside the USB 2.0 specification and is now mostly a thing of the past, having been replaced by micro USB. You may still see mini USB on some older game controllers or digital cameras. Technically, there is both mini USB Type-A and mini USB Type-B, but you are only likely to see mini USB Type-B in the wild. Micro USB From what we’ve been told about Magician 8.0, this release combines all the Samsung software tools, including data migration software, PSSD software and card authentication, into a single tool. And that it should support Windows, Mac and Android. As a result, the 1TB capacity T9 costs 86% more than the 1TB T7, and the larger drives are more than 50% more. Our test rig has an ORICO branded USB card rated for Gen 2x2 mode, and we’ve used this successfully with other drives supporting this mode.

USB 4 moves things on from USB 3.2 Gen 2x2 in a big way, doubling speeds up again to 40Gbps – data transfer levels previously only available to those using Thunderbolt 3 technology, which the new USB standard is built on – but there’s more to this picture than just pure speed, as we’ll explore below. Currently available USB 3.2 Gen 2x2 hosts and devices use silicon from one supplier - ASMedia. JMicron had previously talked in various trade shows about the JMS586 USB 3.2 Gen 2x2 to PCIe 3.0 x4 SSD bridge controller and the JMS591 USB 3.2 Gen 2x2 / eSATA III to 5-port SATA III bridge controller. When retail products using those controllers start hitting the market, the pricing premium that ASMedia commands may temper a bit. 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. Would it have been less confusing if they called it USB 3.2 Gen 3? Who knows?
