The card reader says it's USB 2. But is the USB port 2 or 3? One customer said 3.0, but others say its slow?

Amazon has a problem mixing reviews of different models. From the picture of the back of the WIFISD, it is definitely USB 2.0. I have the enclosure (WIFIHDD) that you add your own drive to and mine is definitely USB 3.0. From the pictures, the WIFIHDD750 and WIFIHDD500 are also USB 3.0. The USB 3.0 device connector is new and quite different from the old USB 2.0 connectors.

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.

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

No its 480mbps high speed 2.0. I like it as its easy to install and works with windows 7 and I have 3.0 on my motherboard and to tell the truth I copied several files from the computer hard drive to a external hard drive and several were over 1 GB and I could not see much difference in speed and the external drive is a USB 3.0. That card does everything I wanted it to do and I have no complaints, its worth the money.

I really don't have any way to measure these things, other than simple observation. My experience has been excellent. Compared to USB 2, this setup has definitely, at the VERY least, doubled the USB 2. When using multiple ports simultaneously, I did not detect any slow-down. Install was easy enough, and the company's support has been very responsive. I needed to contact them because Windows didn't recognize the hardware. Highpoint offered a "dummie" driver to prevent Windows Device Manager from constantly displaying a warning that there is something wrong with a device. The device works very well, and I have never experienced any problems with it. I hope this response helps you!

The card readers are all USB 2.0. Running a benchmark on a Class 10 SD yielded typical transfer rates of 30-35 MB/s.

It will depend on whether the reader port is USB 2 or USB 3. The limit is going to be the read speed of the port. If you use a USB 3 port and reader, it's super fast. The write speed is super fast. The read spead to your computer is limited by the computer device speed. I use a reader for my USB 3 port and it is FAST!

It is a Realtek Card Reader. Pretty much a Generic Universal Multi Card reader. Cards supported = SD/SDHC/SDXC/XD/MSPRO/MS/MMC (support SD 3.0)

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.

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

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!

My system has no trouble with the card. The Amazon cable I purchased does not handle USB 3.0 speeds. I thought the card was bad until I plugged a drive directly into the card.

Yes I am using this card reader with windows 8 kn two different computers with no prpblems at all. The card reader also works quickly and I am happy with it. I am using it on both usb 2 and 3 ports.

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

Get a card reader that will use your existing usb ports. You can pick them up on Amazon, Radio Shack, Walmart, so many places. Get a cheap one....they all work and those that are usb3 compliant might be more than your computer can handle.

You'll first need a USB port to plug the card reader into. Afterthat it's a software issue.

Do you have that card reader in your machine ? I'm using this card with a separate purchased card reader via USB

Though the item listing showed one USB2 port, mine come with all three USB3. The good thing is these port will be backward compatible with USB2 devices so if you mainboard does not have USB2 header connection, you wil need to install a USB 3 adapter card in order to utilize the best performance of this device. Once that is done, all three ports will work as they're suppose to including the card reader itself.
