EOS 600D - which SDHC card

<p>My wife has just bought a 600D (T3i) and we are wondering what speed SDHC card it needs for maxiumum performance shooting stills (3.7Mb/sec at 18 megapixel RAW).<br />She has a Sandisk Extreme HD video card (30Mb/sec) apparently it is a Class 6 card. The 30mb/sec would suggest to me a speed of about 1.8 frames/sec (30MB divided by 18MB) - or do the maths work differently to that? I have had a look on the net for information about SD cards for the similarly-specced 550D but can't find anything.</p>

<p>Any help appreciated!</p>

<p>Thanks, Mark.</p>

<p>I have just re-checked the Sandisk website and it refers to 'Class 6 video performance'.<br>

So a follow up question is whether there is any difference between a SD card and a 'SD HD video' card. It counds like a marketing ploy to me. Or am I being overly cynical?</p>
