Getting ready for 4K :)

If these are cheap enough they might be a viable alternative to standard ssd's

My fear here would be that they lack the controller implementation (or indeed enough separate NAND channels) to deliver in anything other than sequential reads and writes.
I wouldn't expect great performance on random read/writes, nor features such as wear-levelling to be at the same level as comparable SSDs (sorry to be so negative!!)

Indeed - but should help tablets etc. (I'm assuming a micro-sd version becomes available)

Slightly puzzled by the statements about digital photos since you'd need a camera that can both write to card that quickly but also can't clear its buffer that fast? Seems like it's really meant for video use.

Medium format cameras have 50 mp sensors already, you'd need that speed to be snappy!

Don't high-end professional cameras tend to use CompactFlash still since it's easier to get higher speeds out of those before tech filters down to SD or has that changed?

Yup certainly has, only Pro camera I can think of that is still CF is Canon 7D and that's over 3 years old now...

It's normally the flash that is slow, not the interface, at least for the last 5 years. The only reason CF was still used is it was seen as more 'pro' than SD, despite been technically inferior.

Now that just plain wrong.

Canon 1D? Nikon D4? and I'm sure there are a lot more I just can't be bothered raking through spec sheets right now.

Did say that I could think of...lol

Point is it's not as common as other formats any more!

Oh and just checked 1D has CF AND SDHC

XQD card - Wikipedia, the free encyclopedia

Also has a CF card slot.

Most of the reason CF cards are still used in higher end cameras is due to people having a stock of that kind of card and not wanting to replace them all with a new body. Well, there probably is an element of pro's feeling superior because they use different card to everyone else.

SD cards have caught up, but CF was much better until a few years ago.

Pedantic I checked the 1D and not the 1D X.
I know what you mean but the amount of CF toting cameras is coming down rapidly. Even buying CF cards is getting harder, the form factor alone is losing them sales I reckon as SD is much smaller...but anyway that's off topic completely. SD is the way forward and I believe CF's time is very limited
