About this deal

And then, in desperation, we swapped the provided PNY cable with another that came from a Seagate One Touch SSD, which is ironically only Gen 2 speed rated. Also, we were sent a statement from Kingston as to why the technology is NOT compatible with Thunderbolt 4 or Thunderbolt 3:

USB3.2 Gen2(x1) – newly marketed as SuperSpeed USB 10Gbps (replaces SuperSpeed+ or SS+), [59] 10 Gbit/s signaling rate over 1 lane using 128b/132b encoding (nominal data rate: 1212 MB/s); replaces USB3.1 Gen2. a b c d "The USB 3.2 Specification released on September 22, 2017 and ECNs". USB.org. USB Implementers Forum. September 2017 . Retrieved 14 October 2019. If the external device has an appropriate connector, it can be powered by an external power supply. PiranhaTech said:I'd like USB-C if it was actually a Universal cable and more reliable. There's too many variants, with some ports and cables supporting one standard, then other ports and cables supporting another standard... On top of this, sometimes you have to flip the USB-C cable to get it to work. Then we have the potential different wattage capacities of each cable.While our benchmarks aren’t definitive, they reveal that the T9 is a good performer and gets close to the theoretical limits of the USB 3.2 Gen 2x2 interface. In 2008, USB-IF introduced USB 3.0, which ran at a speedy 5 Gbps, offering roughly a 10x improvement in throughput over the preceding USB 2.0. Even today, that’s the top speed that most devices support. In fact, most peripherals only need USB 2.0 speeds. What we did like about the T9 was that Samsung included both USB-C and USB-A cables in the box, although they didn’t provide a pouch to carry those around when the drive wasn’t in use. Bright, Peter (26 July 2017). "USB 3.2 will make your cables twice as fast ... once you've bought new devices". Ars Technica . Retrieved 27 July 2017. USB was developed as a "universal" replacement for all these ports, simplifying how we connect devices by settling on a common connector.

If you're using a USB Type-C cable and port, the charger / host device could support USB Power Delivery (USB PD), which can go as high as 240 watts in some cases. But the wattage has nothing to do with data speeds as a USB 2.0 port could have power delivery while a USB 3.2 port might not. Video Over USB 3.2 / USB 3.1How was it any different than USB-A? USB-A had 1.1, 2.0, 3.0, 3.2. There wasn't a cable issue with 1.1 or 2.0, but 3 and 3.2 it started to matter. The latest USB4 ports on laptops can utilize DisplayPort Alt Mode 2.0, which can run at up to 8K resolution at 60 Hz and use HDR10 color. Though USB4 itself can only do 40 Gbps of data, the port can send 80 Gbps of DisplayPort data, because it sends all the data in just one direction and can therefore take over all 8 lanes.

Note, we said ‘can be’ because the exercise of testing this drive proved to be much more challenging than we’d anticipated. a b c d "Universal Serial Bus Revision 3.0 Specification".

Retrieved 19 January 2014. No, this is not the police department for the town of USB. USB PD stands for USB Power Delivery and offers a way to charge all manner of devices. What was once a convenient way to charge your phone in a pinch, USB is now designed to charge larger, more powerful devices with larger, more powerful batteries. USB PD can reach up to 100 watts, enough to charge That overarching plan to eventually transition all devices across to using Type-C connectors and USB 4 is a laudable goal, but obviously that won’t happen anytime soon. While the first USB 4 devices should emerge in 2020, widespread adoption of the standard will be a lot further away, and likely a very slow process for price-related reasons.USB 3.0 ports may implement other USB specifications for increased power, including the USB Battery Charging Specification for up to 1.5A or 7.5W, or, in the case of USB 3.1, the USB Power Delivery Specification for charging the host device up to 100W. [14] Availability [ edit ] Internal circuitboard and connectors of a USB3.0 four-port hub, using a VIA Technologies chipset In May 2018, Synopsys demonstrated the first USB3.2 Gen2×2 operation mode, where a Windows PC was connected to a storage device, reaching an average speed of 1600MB/s, [66] [67] which is 66% of its raw throughput. The USB3.0 specification is similar to USB2.0, but with many improvements and an alternative implementation. Earlier USB concepts such as endpoints and the four transfer types (bulk, control, isochronous and interrupt) are preserved but the protocol and electrical interface are different. The specification defines a physically separate channel to carry USB3.0 traffic. The changes in this specification make improvements in the following areas:

Initially, the Elite-X PRO refused to use Gen 2x2 mode and instead defaulted to Gen 2 operations, capping the speed to around 1,000MB/s. To further complicate things, the transfer speeds themselves received names. USB 3.1 Gen 1, originally known as USB 3.0, is capable of 5 Gbps transfer speeds---that's called SuperSpeed. In theory, USB logos should help. As seen in the image above, the SS and 10 denote that USB cable as a SuperSpeed cable capable of 10 Gbps transfers. Unfortunately, the USB-IF has not shown the official certification mark for SuperSpeed USB 20 yet. Presumably, it should be the same logo as above, just with a 20 in its place. But we don't know that for certain yet.Both USB4 20Gbps and USB4 40Gbps are mandated to support only up to USB 3.2 Gen 2 speeds - that is 10 Gbps. Vendors can optionally support higher, but the minimum needed for certification is 10 Gbps. 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.
