What's the difference between 2.0 and 3.0 usb memory card reader?

I'm sure the speed is the difference. I have a 8 year old iMac and a 4year old MacBook Pro and it works great on both.

Short answer? speed; as in, data speed. A USB 3.0 memory card reader, plugged into a USB 3.0 port on your computer or laptop, will move data back and forth much faster than the USB 2.0. I don't have the exact figures at my figertips, but trust me, the difference in speed is significant. You can find USB 3.0 ports on newer desktop and laptop computers by looking for the blue connector post in the USB port. If you look closely, next to the port you'll also see the letters 'ss' (for 'superspeed') and what looks like a tiny lightning bolt next to the letters. That also identifies the port as a USB 3.0 port, but the blue port connector post is the giveaway. Finally, as with most any upgrade of equipment, a USB 3.0 device/port will work with older USB 2.0 devices/ports, you just won't have the increase in data speeds. Hope this helps!

this site explains it pretty well. http://www.usr.com/education/peripherals0.asp

USB 3 is the latest technology; most current computers use USB 2. However a USB 3 is backward compatible and can run USB 2 devices.

You know what, USB 3 might be useless. It won't transfer faster than what you SDHC for example can transfert. Mine iis 30mb/s, so USB 2 can tranfert more than 4 time what my SDHC can, but it will be limited. So the answer is USB 2 is probably enough.

It's faster, but unless you know that your computer has a 3.0 USB port,better get the 2.0 reader.

I use easy ACC super speed USB. It comes with two slots for card reader. It's great you can buy at Amazon for $7.95.Good luck

Based on when this was introducer, I doubt it's USB 3. If your internal storage is either flash or SD, it really doesn't make much difference whether you have USB 2 or USB 3 port speed - the storage element write speed will be the gateing item.

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.

I'd bet just USB 2.0 because the memory card connectors attach to one USB 2.0 Motherboard header. Given that the theoretical maximum bandwith is 60 MB/s, you won't be able to surpass that. The USB 3.0 ports have their specific 19-pin connector.

The size of the memory of the card is not a factor. The only factor is the physical size of the card. As long as it is a SD/SDHC you are good. This reader works great for older model laptops which have USB ports but do not have a SD/SDHC slot. I also use a USB hub to give me more access to plug in SD cards or thumb drives, etc. I have purchased two (one for me and one for my wife) and we have never had an problems.

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.

Yes. Usb 3.0 flash drives wors in both 3.0 and 2.0 and the same goes for 2.0 flash drives

I remove the SD memory card and use an inexpensive USB adapter to download the files to my computer.Here's one available from Amazon : eForCity SDHC / SD / MMC Memory Card Reader to USB 2.0 Adapter, Smoke

Yes, you can use a 3.0 flash drive in a 2.0 usb slot. I would be faster if you have a 3.0 slot. You can tell if the slot is 3.0 by looking at the slot, if it is 3.0, it will have SS next to the slot.

Regarding the USB 3.0 question, those are the specifications. The card reader handles multiple different storage card types including CF, SD/SDHC/SCXC, microSD, M2 etc. I have used the card twice, it worked easily, right out of the packaging. Seems to be a good buy.

If you are going to use a different USB adapter / card reader, it must be SDHC compatible or it will not recognize the card. I have an older adapter that is not SDHC compliant and it will only read up to a 2GB card.

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...

Sorry, I don't know. If you searched your model number and determined if it had a USB 3.0 port, you'd know since it will not work as fast with a 2.0 port.

It works with USB 2.0. I didn't notice a difference between using USB 3.0 and 2.0.

If you have 2 ports for connecting USB devices version 2.0 and one USB 3.0 port for use as internal storage or hard disk reading

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.
