What is the difference between a 2.0 usb port and a 3.0 port? Can I plug the 3.0 flash drive into a 2.0 usb port on my computer?

the difference between usb 2.0 and usb 3.0 is the data transfer speed. 3.0 is can be 10x faster than 2.0, the other difference is 3.0 has 9 pins, 2.0 has 4pins a usb 3.0 drive can be plugged into a computer that has 2.0 but the drive will operate at 2.0 speed

USB 2.0 has much slower file transfer rates than USB 3.0. Yes, almost all USB 3.0 flash drives are compatible with USB 2.0 ports and will work fine, but at the slower USB 2.0 Speeds. For the best performance (Faster File Transfer Rates) a USB 3.0 Flash drive must use a USB 3.0 Port (usually blue colored) on the computer.

The usb cable it comes with has 2 different ends to connect to your computer. I am guessing one is 3.0 but I don't know the difference to look at them.

It'll just be the USB 2.0 device that runs at the 2.0 speed. Your 3.0 devices will still run at 3.0 speeds. BUT take note of any bottleknecks! If your computer doesn't support 3.0 or you don't use a 3.0 port, you will not get 3.0 speeds! Also, something like transferring a file from a 2.0 ext HDD to a 3.0 ext HDD will only operate at 2.0 speeds max.

USB 3.0 is newly developed with slightly different connector. USB 2.0 is 60 mb/sec (35-40 typical) data rate , high-speed, whereas 3.0 is 625 mb/sec (400 mb/sec typical) data rate, superspeed. USB 2.0 has 4 wires plus braided outer shield, 3.0 has 10 wires plus braided outer shell. The wire included is USB 3.0 on one end (device) and a USB 2.0 on the other (computer). Data rate I suspect will be limited to USB 2.0 data rate. For full USB 3.0, you would probably need cord with USB 3.0 on both ends and computer with USB 3.0 socket.

If you mean usb 3.0, then the answer is no. Check the specs for the various flash drives you're looking at, they should say whether they're 2.0 or 3.0...

Yes, all USB 3.0 is backwards compatible with USB 2.0. I thought my comp had 3.0 when I bought this, turns out I only have 2.0. Works great.

Yes. A USB 3.0 flash drive will be faster than USB 2.0. Keep in mind however, that budget 3.0 flash drives are slower than more expensive 3.0 drives that have faster memory.

My similar drive (5TB) is also equipped for USB 3, but it works great on my 2.0 ports. I assume it could transfer faster on 3.0, but there's no incompatibility.

Yes, I use it for both USB 3 and 2 and it works fine. But it is a lot slower with 2.0.

I use it in a USB 2.0 port. It is slower than if it was in a USB 3.0 port. However, it is considerably faster than my older Kingston 32GB flash drive. It's a good device.

Both, it has a single USB 2 port and two USB 3 ports and USB 3 is backward compatible - hope that helps. Almost all of my old accessories are USB 2 and they work in any of the ports.

USB 3.0 is backwards compatible with 2.0. However, you will not see the performance increase as the hardware inside this device only supports 2.0. To reiterate, yes, you may plug this into a 3.0 USB port and it will work 100% as specified at the performance of a USB 2.0.

Peter is right. It will be faster than most usb 2.0 flashdrives in a USB 2.0 port but it will not be as fast as if you used it with a USB 3.0 port. Either way it should be faster than any flashdrives that you currently have even in a USB 2.0 port.

Yes, it is. And in general USB3 flash drivers work on PCs with USB 2.0 ports, just that it will be at a lower speed, which we wont probably notice from small to medium size files.

USB 2.0 port will remain a USB 2.0 port because of the bus speed. It won't make it 3.0 even if you plug in this hub. Hope this helps.

I've plugged it into USB2.0 port to save a drive on an older box, and it works fine. Somewhat slower than USB3.0, as you would expect.

Yes, & I agree with Dave; as a general rule I have found most 3.0 drives to be faster on a 2.0 port than a 2.0 drive. And in my experience, this is also one of the better ones.
