For example, when previously using a USB PD 2.0 device, your hard drive may have been disconnected when unplugging the power source. USB PD 3.0 charging may prove to be more beneficial when using with an external hard drive. For example, if an over-current or over-voltage occurs while charging, your device will notify you with a data message of the mishap. This includes reporting any malfunction or system change within the device, temperature of the device, or what may be causing hold ups or decreased charging speed, etc. The difference between the two types of PD charging lies in the amount of detailed information given by each.USB PD 3.0 has worked to improve its power delivery but is primarily known for offering increased amounts of information about the device being charged and its power/ battery. Sources >45W supply 5 volts, 9 volts, 15 volts, and 20 volts Sources >27W supply 5 volts, 9 volts, and 15 volts Power Rules for both USB PD 2.0 and USB PD 3.0: All USB PD 3.0 devices work with USB PD 2.0 as well. The power rules of the two are in fact the same. Take note that the differences between USB PD 2.0 and USB PD 3.0 don't lie in the power rules. Satechi products such as our Type-C 75W Travel Charger and USB-Car Charger Adapter offer USB Power Delivery. This power source allows compatible devices to share chargers as well. These devices must be charged over a USB connection. USB PD gives devices the ability to be charged or re-powered quickly. The latest version of USB Power Delivery, USB PD 3.0, has people asking, what separates it from USB PD 2.0? In order to understand their differences, let's delve into what USB Power Delivery is.

The fastest USB 3.0 transfer speed we've recorded is 275MB/s using the HPT RocketU Quad USB 3.0 host adapter on a 2010 Mac Pro connected to the Koutech ASU330 bridge.SAN DIEGO- (January 3, 2018)- Due to the growing excitement and love of quick charging, USB Power Delivery (USB PD) and its capabilities have become highly talked about in the tech world. The raw throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (0.4 GB/s or 400 MB/s) or more. The "SuperSpeed" bus provides a transfer mode at 5.0 Gbit/s additionally to the three existing transfer modes. There's a lot of USB 3.0 enclosures to choose from but our graph shows that, in terms of performance, they are not all created equal.Īnd none of them came close to the theoretical speed of USB 3.0. To summarize, USB 3.0 is dramatically faster than USB 2.0 and FireWire 800, but not as fast as T-SATA, SATA, and Thunderbolt storage solutions. I know there's a lot to consume in the above graphs.
