If I get a 64GB SDXC card that claims to support 90 MB/s, will this reader utilize the higher speed USB 3.0 for it, or just USB 2.0 connection?

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 card reader section of the device connects to the USB 2.0 ports on the motherboard so yes, you will experience USB 2.0.

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.

Personally I alway go by "you get what you pay for". I actually use the SanDisk Extreme III card. It has a 30mb/s rate, highest in its class I believe. The cards are a little on the expensive side, especially for the 16GB, but worth it I think. Because of the high compression rate, it take a while to download/transfer files, this helps with that when you have an average computer. Not an overwhelming difference, but enough to say "Awesome".

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.

Yes----The front of the package has a speed reference that is noted that it was obtained with a Transcend 128 GB SDXC UHS-I card so it would appear that this reader supports at least up to 128 GB cards. Technically your 64 GB card is an SDXC card. See the definitions below. Capacity of Memory (1) Standard Capacity SD Memory Card (SDSC) : Up to and including 2 GB (2) High Capacity SD Memory Card (SDHC): More than 2GB and up to and including 32GB (3) Extended Capacity SD Memory Card (SDXC): More than 32GB and up to and including 2TB This reader supports all 3 types above including UHS-I (Ultra High Speed) versions.

It is most logic it does, but I would not assure it does. The Micca reads files on hard drives up to 2TB, the owner's manual only mentions SD/SDHC, it might be due to the date it was written, or that the Micca does not read the SDXC cards. I use SDHC up to 32 GB with no problem. SD cards are built backwards compatible, but devices are not built "future" compatible, it is just a matter of try and verify. I just don't have a 64 GB SDXC card.

It's able to read a 32 gig Micro SDHC card for sure, as that's what I use with mine, but I'm not sure about the 64 gig SDXC card, since they switched over to an entirely new file system for that format and I was too scared to risk the money on the larger card in case it didn't work.

There is absolutely no difference in the video quality when using an SDHC or SDXC. If you have two 32GB CD cards with identical read/write speeds and one is SDHC and the other is SDXC, there will be no difference. SDXC is a format that allows flash cards to be larger than 32GB, and not all devices support SDXC cards. It is not possible to find a 64GB SDHC because SDHC maxes out at 32GB. The only situation that I can think of where you should care which one you buy is if you plan to use that flash card on other devices besides your X920. Many older devices do not support the SDXC cards.

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.

Although I haven't checked the actual transfer speed, it is fast and does support SDHC and SDXC cards.

I use 64gb SDXC (as fast as I can get) as my regular card and I've never had a problem.

Keep in mind this is a USB3.0 hub, while it is USB2.0 backwards compatible, it could give you potential issues. Not just that, but you also need to be mindful of the file system you format the SD card you'll be using with it. I believe most USB readers are compatible with FAT32. So as long as you're using that, chances are it should work.

I use this reader exclusively on Windows 7 in a USB 3.0 port. It works well and fast. If your having a problem it may be your particular unit.

in your manual or specs verify that your slot can read an SDXC card. I would assume all the newer devices do. But verify

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 reads my type 1 Sandisk extreme 32GB CF card just fine. Type 2 cards are a bit thicker though. Not sure if it will completely fit. Btw, get the usb 3 version rather than this usb 2 version

I got the SAMSUNG MicroSDXC 64GB PRO Class 10 UHS-I Card for the fast read/write speed (70/20mbs). Search for best price!

I had to upgrade my card reader to one that stated that it supported UDMA 7 cards to utilize the full transfer speed of this card. The cheap 50 in 1 type card readers I had wouldn't recognize the card at all. A better quality, but much older and slower (USB 1.1) dedicated compact flash card reader that I had in the back of a drawer read the card just fine. It took hours to transfer the data, though. A new card reader that specifically stated it supported UDMA 7 read the card with no problem and transferred the data much closer to the advertised speeds.
