Excerpt: This SD card is the fastest U1 class 10 card you can buy. Sandisk reliability is second to none and comes with a lifetime warranty. I wouldn't risk getting a slower, less reliable card to save a measly few bucks.
Excerpt: I bought this card when I started having buffering delays with a 30 megabit/sec card on my Canon 6D when shooting on continuous raw.The higher speed of this card Is great - well with the small price premium. Will definitely buy extreme pro going forward.
