what is the difference between 2.0 usb and 3.0 usb? do I need a converter or a new comuiter?

3.0 USB is a newer, faster connection, however, the backup will work fine with 2.0 or 3.0

new computer or just use your computer and it will just work a little slower.clickfree is very easy and simple to use.just plug it in.great phone support.

Yes absolutely,but speed wont be same as usb3.0. So hence you will get regular speed with USB 2.0.

all USB 3.0 slots are backwards compatible with 2.0 it's not a matter of the card

USB 2.0 peripherals are backwards compatible with USB 3.0, so yes, it shouldn't be an issue.

If it has a USB port.....It will work like a thumb drive does......You don't need 3.0 USB.....It's a bit slower with a 2.0 naturally.....

It says 2.0, but most standard USB 3.0 built into laptops are usually backward compatible with USB 2.0 devices.

Sorry, I made a mistake. The USB 2.0 read speed is 30 megabytes/sec and the USB 3.0 read speed is 255 megabytes/sec., i.e., bytes not bits.

The connections are the same, I plug USB 2.0 into the 3.0 ports all the time. I assume they are compatible the other "direction."

Yes, all USB 3.0 devices will work in a USB 2.0 port, they will just run significantly slower due to the limits of USB 2.0 technology.

If you plug a usb 2.0 device into a usb 3.0 slot it was operate as usb 2.0.

I plugged mine into a 2.0 computer. The drive allows for a 3.0 connection, but works with a 2.0.

This box has both USB 2.0 and 3.0, so the 2.0 will work for sure, not so clear if the 2.0 can be replaced for the 3.0 or not?

USB 3.0, the latest version of USB (Universal Serial Bus), provides better speed and more efficient power management than USB 2.0. USB 3.0 is backward compatible with USB 2.0 devices; however, data transfer speeds are limited to USB 2.0 levels when these devices inter-operate. The connection is the same.

It really doesn't matter, because no CD/DVD drive is going to send or receive data faster than USB 2.0 can comfortably handle. Having a USB 3.0 connection would not speed up the drive's performance. (As pointed out elsewhere, USB 3.0 ports are backward-compatible with USB 2.0 peripherals, so the drive will work whether the port you connect it to is USB 2.0 or 3.0.)

you certainly can use both USB 3.0 and USB 2.0; the only difference is transfer speed.

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...

No. Connecting a 2.0 to 3.0 in any direction will always result in the lower speed of the two. However, they ARE compatible with each other, but you can only get a maximum of USB 2.0 out of this particular reader.
