Afraid not at this stage.

..and any remaining benefit of CF cards reduces further.

XQD (the successor to CF) starts at 125MB/s.

XQD (the successor to CF) starts at 125MB/s.

Actually, it 'ends' at 125MB/s - speeds 'up to'. And at vast expense - and I said 'reduces further', not 'is removed'


The simple fact that you can get 32GB Class 10 SD cards for <£20 while the cheapest CF cards are at least £50 for 32GB, and while the top end CF/XQD cards are less than 30% faster than top-end SD cards, says to me that for almost all usage scenarios SD is the better format. It is cheap at entry-level and has performance up to professional, whereas CF cards only cater to professionals because of the high starting price.

Edit: in fact 32GB 90MB/s SD cards are available for around £70, while the 32GB 125MB/s XQD card you linked to has a price of $229.99.

You're wrong. From Wikipedia...

The new format is targeted at high-definition camcorders and high-resolution digital photo cameras. It would offer target read and write speeds from 1 Gbps (125 Mbyte/s) to about 500 Mbytes/s and storage capabilities beyond 2 TB.

Class 10 SD cards are cheap because they are slow (~10MB/s).

Then I stand corrected; however from your own link:

Sony says that the cards boast data transfer rates of up to 1Gbps/125MB/s write and read.

And I doubt you'll find any XQD cards at 500MB/s? Or in fact any faster than 125MB/s. And since really what we're talking about is currently available speeds, that takes us right back to where we started.

Class 10 SD cards are cheap because they are slow (~10MB/s).

So where are the cheap, slow CF cards? And 10MB/s is more than fast enough for anything your typical consumer will want to use them for, which includes 1080p video at 60fps. Which was kindof my point - SD cards are cheap, quick enough at the cheap end for consumers, and fast enough at the top (more expensive) end for professionals, while still remaining a third of the price of Sony's XQD cards (offering around 75% the performance).
