The Sony Memory Stick Pro-HG Duo HX is actually pretty fast!
http://www.dpreview.com/news/1005/10051303...tickhx30mbs.asp
Read 30MB/s, write 15MB/s.
A Class 10 SD card promises a write speed of 10MB/s (with the read speeds usually being the x multiplier... but often not too impressively 150x which is 22.5MB/s read only.) And this is sold as the advanced class SD card.
By comparison, a consumer CF card is already doing 133x in 2007 like it was nothing.
That said, I have gotten a Sandisk Extreme Pro UHS-1 SDHC card - this promises 45MB/s read and write which is 300x. Still slow compared to the CF cards. This card is not for my NEX-5 as my MSPD HX will do 5 bursts of 7 FPS just fine, and I don't use it for any more than that. This card is for the A77.
