Am I the only one noticing that it is both UHS-II certified and boasts a the UHS Speed 3 rating? So it is both UHS-II and UHS-III?

This will not speed up the burst mod on something like a 1Dx that does 12raws a second. The internal camera buffer fills up before it can write it to the card regardless of how fast the card is. IF the card is to slow the camera will stop shooting burst faster but no mater how much faster the card is after that the camera is still going to fill up its own buffer in the same amount of time.

I can see this working really well for still shots, But I think for the price/GB and speed, I'd prefer the video camera that lets you put in a 2.5 SSD. RAW HD footage would use up that 64GB very quickly.

This is backwards compatible with older formats, right? I could stick this in a 4 year old DSLR and be ok?

It has an extra row of pins

Google SDXC UHS-II cards
Wikipedia>
UHS-II cards, defined in Version 4.0, further raise the data transfer rate to a theoretical maximum of 312 MB/s using additional row of pins

It is also ExFat format but SDXC cards can be reformatted to use alternative file systems, for example FAT32 which supports volumes up to the SDXC's maximum theoretical capacity of 2 TB, and can be used in a SDHC host device that can handle volumes larger than 32 GB. However using alternative file systems bears a risk of accidental loss of data, as the host device may treat a card with unrecognized file system as blank or damaged and reformat the card.

The newer card readers are backward compatible but the cards should be used in the hardware it was designed for

The card "might" work in an older reader but will likely be much slower if it does

Now if only SD card interfaces stopped piggybacking on USB2.0... (or I'm slow and they've finally moved on to 3.0)

That's why they are selling a card reader as well. It is rated for USB 3.0.

"SanDisk is also announcing the SanDisk Extreme PRO SD UHS-II Card Reader/Writer, the world’s first SDHC/SDXC UHS-II memory card reader/writer, designed to increase workflow efficiency. Small enough for fieldwork, the compact reader is built to handle the high-performance demands of UHS-II card technology. This reader/writer features a USB 3.0 interface, which is capable of transferring card content up to 500MB/s, 10 times faster than a USB 2.0 interface6."
