Is this USB 2.0 or 3.0? If it does support 3.0 will using a USB 3.0 slot make any difference in performance?

This is USB 2.It will work with USB 3.0. I do not see any improvement in performance.

I believe it is a 3.0. I plugged into a USB port of which i do not know if it is a 3.0. But it works great from a distance of 40ft through walls.

It will work with USB 2.0, just considerably slower. In my very informal testing it was about 1/3 as fast when plugged into a USB 2.0 port than when using a USB 3.0 port.

Absolutely. I've found that, while it's not as fast as on USB 3.0, obviously, it's still faster on USB 2 ports than many other USB memory sticks!

Yes, it works fine in USB 2.0 ports, usually faster than a 2.0 flash drive in the same port. You won't get the screaming speeds of a 3.0 flash drive in a 3.0 port, but it's definitely an improvement over the 2.0 flash drive.

It should work it but not as fast as it should.USB 3.0 is backwards compatible.

Yes, it works fine in USB 2.0 ports. That said, the main advantage of this drive is its fantastic speed, so I'd consider it a bit of a waste to purchase for use specifically with a 2.0 port.

I only have usb 2.0 on the computer I upgraded and it worked fine. most (maybe all) devices that work with usb 3.0 will also work with 2.0.

The newer model is actually cheaper for some unknown reason. As far as I can tell that is the only difference since USB 3.0 is backwards compatable with USB 2.0 ports.

The box only mentions USB 2.0. I would guess a USB 3.0 should be ok, just won't get the 3.0's speed rate for data.

Yep. Works fine on mine at least. To my knowledge, USB is always backwards compatible, you may just run into speed limitations on some devices. This thing doesn't come anywhere close to needing all the speed of even 2.0, so there's really no difference.

USB 2.0 will be as fast as it was designed for. Inserting it into a USB 3.0 slot will only allow it to run at it max speed 480 megabits / second.

Every USB 3.0 device is 2.0 compatible... you just loose speed/throughput and extremely high resolution, multi-monitor setups with GbE all running at the same time would likely suffer.

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.

usb 3.0 is only avaibly through usb 3.0 slot. The card reader is through serial ATA.

you certainly can use both USB 3.0 and USB 2.0; the only difference is transfer speed.
969848
Yes. It is actually rated for USB 3.0. USB 2.0 is only a data transfer rate. 2.0 can transfer 480 Mbits/sec. USB 3.0 (which is what this is rated for) transfers up to 5 Gbits/sec!

No. Unless the USB device works on USB 2.0. It won't be as fast as with USB 3. I agree with Robert.
