Excerpt: I use this card as a backup to my CF card in my Nikon D800e.
It can easily keep up with my 800x card if I ever need to shoot many sequential shots in a row.
I have had no problems with this card at all.
Excerpt: This care has performed great, though I had a SanDisk card previously that shat the bed after about a year or so. So I can't give it the full 5 stars being that it's only been a few weeks. But SanDisk has been very good, especially at the price point, in my experience.
