Is the USB 3.0 unit backward compatible to 2.0 and 1.1?

I know it's backward compatible with 2.0 (just won't get the high speed transfer), and I'm pretty sure it's compatible with 1.1 since this is what their website states for requirements:"Desktop or notebook PC with an available USB port (USB 3.0 recommended)"

Yes as far as I can tell. I've had no problems with it and the only 3.0 port I have access to is at work. Everything I've plugged it into so far has recognized it.

Yes, it works perfectly with any usb 2.0 port, it just doesn't run as fast as a 3.0

Yes. It is backwards compatible. I would think all USB 3.0 devices are but in this case I have used the device on the laptop I am typing from and it older and only has USB 2.0 ports.

That really depends. Do you plan on upgrading in the near future to have a USB 3.0? If you are then the clear answer is to get the USB 3.0. USB 3.0 devices are backwards compatible with USB 2.0. If you don't plan to upgrade at all, then save the money and buy the 2.0 version.

Hi Eric. Yes, it will work on a 3.0 USB port since USBs are forward and backward compatible. The difference will lie on the maximum speed supported by each one.

All USB3 devices are backwards compatible to USB 1, or USB 2. On USB 1 or USB 2 you will see reduced performance due to them being slower standards than USB 3.0

Yes it is backwards compatible I use it in USB 2.0/3.0 with no problems. Also faster in respect to other 2.0 giveaway/throw away type thumbdrives.

Some are and some are not. They usually indicate if a 3.0 is backwards compatible with 2.0 on the package or description. This particular USB 3.0 works with 2.0 as well and it has been working just well for me.

Yes! I have USB 3.0 and 2.0 I really can't tell the difference between the two in speeds...

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

Yes, it will work since USB 3 standard is backward compatible with USB 1.0, 1.1 and 2.0.

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

Yes. There are 2 USB 3.1 Type A ports built into the back, next to the USB 3.0 ports

Yes. One of the built in redundancies of USB 3.0 (as it was with 2.0) is that they are backwards compatible with the previous interface. The limitation being that it can only run at the top speed of said interface. But I have used this device on Thunderbolt, USB 3.0 and USB 2.0 plugs and all work great!

Have not tried any first gen USB devices yet but it has handled everything I've thrown at its I far. I would imagine its backwards compatible but as I don't own any I cannot confirm 100%

These enclosures are indeed backwards compatible with USB 2.0 due to the fact that all USB 3.0 devices are backwards compatible with USB 2.0 and vice versa.

All USB 2.0 devices are backward-compatible, but they will of course function more slowly.Buying and installing a USB 2.0 card in your machine may be a worthwhile investment.
