The same process was then repeated with a USB 3.0 port and a wall charger. We first connected our Note 3 to a desktop computer's USB 2.0 port and recorded the time it took for the phone battery to charge from 0 to 100%. Samsung's Galaxy Note 3 is the first phone in the world with a USB 3.0 port, making it ideal for comparing USB 2.0 and USB 3.0 charging speeds. This means two things: USB 3.0 devices are able to charge faster and USB 3.0 ports can support more power-hungry devices. USB 2.0 vs 3.0: Charging and PowerĪ USB 2.0 port is able to deliver 0.5 A of power while USB 3.0 is able to output 0.9 A.

there is little performance difference between USB 2.0 and 3.0. USB 3.0 mobile phones and tablets are also 2 to 3 times faster when transferring large files from their internal memories.īut for other USB devices such as external optical drives, keyboards, mice, webcams, printers, speakers, network adapters etc. USB-C: Whats the Difference) Youll only see the speed benefits of Thunderbolt 3, however, if you have a drive thats SSD-based, or a multi-drive.

Yes, external hard drives and flash drives will be able to take full advantage of USB 3.0's speed boost. However, most articles fail to mention one very important point: Not all devices will benefit from USB 3.0's superior transfer rates. Our results indicate that USB 3.0 is about 2.5 times faster, which tallies with findings of the other real world tests. We first connected it to an USB 2.0 port and recorded its speed, then repeated the process with a USB 3.0 port. We connected a Toshiba Canvio USB 3.0 external hard drive to an idle desktop computer and measured its transfer speed with CrystalDiskMark. To verify this, we performed our own USB 3.0 vs 2.0 speed test. While this falls short of its marketing claim, 3 times faster is still a significant speed boost. Real world speed tests by TweakTown, NetworkWorld and even The New York Times have all led to similar results: USB 3.0 is about 2.5 times to 3.5 times faster than USB 2.0.

This would suggest that USB 3.0 is at least 10 times than USB 2.0, but we all know these figures are meaningless unless it's backed up by real world tests. On paper, USB 2.0 is capable of transfer speeds of up to 480 Mbps while USB 3.0 caps out at 5,000 Mbps. Promising higher transfer speeds and quicker charging, does USB 3.0 deliver? Read on for the full answer: USB 2.0 vs 3.0: Speed Difference While it has enjoyed tremendous popularity for over a decade, its successor USB 3.0 has been gaining rapid adoption among newer devices. computers, laptops, tablets, phones, cameras, storage devices, televisions and even bitcoin miners. Since its release in 2000, USB 2.0 has made its way in almost every device imaginable.
