There’s no harm in having such devices be USB 3.0 - especially given the backwards compatibility - but there’s no sense in paying extra for that. USB 2.0 provides power up to 500 mA whereas USB 3.0 caters up to 900 mA, resulting in an increase in total power delivery from 2.5 W to 4.5 W (at 5 V). Of course, eventually USB 3.0 will take over and all devices will use USB 3.0 or newer. USB 2.0 vs 3.0 Power Management Compared with USB 2.0, USB 3.0 also provides more efficient power management and increases power delivery. If you use a USB mouse and keyboard, you won’t see any sort of input speed improvement by moving to USB 3.0. Don’t just believe the manufacturer’s quoted speed rate, as manufacturers often give you the most exaggerated numbers to mislead you - look up independent benchmarks on your own.īear in mind that many types of devices won’t perform faster just because they use USB 3.0. If you’re looking for a good, fast USB drive for serious use - and not the cheapest $5 drive - you should look up benchmarks ahead of time and determine just how fast your drive of choice is. RELATED: 8 Ways Hardware Manufacturers Are Deceiving You Other factors, such as the speed of the flash memory inside the drive, are critical. USB 3.0 allows for much faster transfer speeds, but not every drive will take advantage of that. You’ll have to spend more for an actual speed improvement. However, reviews indicate that it performs at similar speeds to USB 2.0 drives. At the moment, Amazon is selling a 16 GB USB 3.0 flash drive for just $15.
Silicon Power 32GB USB 3.0 Flash Driveīear in mind that just because a drive is USB 3.0 doesn’t mean it’s all that much faster. 4 GB flash drives can often be found on sale for $5. Many USB 2.0 flash drives are super cheap - for example, you can pick up an 8 GB USB 2.0 flash drive for under $10 on Amazon. The fastest drive seems to achieve its speed by using “four channels of flash” memory instead of a single one. Unsurprisingly, the slowest drives were the cheapest, while the faster ones are more expensive. These changes should help consumers better distinguish between the two standards. Instead, cords and even ports are colored with a bright blue hue (as well as a more curled and swirled SuperSpeed logo imprinted on the connector). The best USB 3.0 drive was over 28 times faster.Įditor’s Note: if you want a great USB 3.0 Flash drive, click here for the one that How-To Geek uses. USB 3.0 takes a departure from USB 2.0’s black and gray cables. The worst USB 3.0 drive was faster than the USB 2.0 drives, but only by a tiny bit. What’s really interesting here is the huge variation in speeds. The USB 3.0 drives they tested go from 11.4 MB/s all the way up to 286.2 MB/s. The test also includes a few USB 2.0 drives, which are at the bottom of the charts at between 7.9 MB/s to 9.5 MB/s in write speed.

Scroll down until you see 'Universal Serial Bus Controllers' and expand that section - if you see any items with 'USB 3.0' or 'xHCI' in the title then your PC is equipped with USB 3.0. In Control Panel, click 'Hardware and Sound' and then 'Device Manager'. To access Device Manager click on the Start menu and open Control Panel.
If you are still not sure if your PC has USB 3.0 ports, the next place to check is Device Manager. You can also check the logo above the port for the USB 3.0 SuperSpeed logo (pictured below).
