Nikon D3s/D3x SanDisk CF

<p>Is there <strong>ANY</strong> actual performance difference between the two types of CF cards below when using with Nikon D3s/D3x bodies (at max. resolution and with all functions, including continuous shooting, video, etc.)?<br>

<strong>64GB CompactFlash Memory Card Extreme Pro 600x UDMA</strong><br />http://www.bhphotovideo.com/c/product/646880-REG/SanDisk_SDCFXP_064G_A91_64GB_Extreme_Pro_CompactFlash.html<br>

<strong>64GB CompactFlash Memory Card Extreme 400x UDMA</strong><br />http://www.bhphotovideo.com/c/product/843240-REG/SanDisk_SDCFX_064G_A61_64GB_CompactFlash_Memory_Card.html<br>

An other questions: is the Extreme Pro more reliable, durable, better made than the Extreme? Or the difference is just in the data transfer rate?<br>

Thank you!</p>

<p>I don't own a D3 series body yet but over on the Nikonians.org website I've seen results from users stating that the faster cards are just that, faster and the D3 takes full advantage of the speed. Check them out, they are a good resource for information regarding the D3 and other Nikon products.</p>
