If you're in need for big, fast memory cards for shooting photos and HD videos, now would be the time to bust out the credit card and start waiting for the delivery man.
We first laid eyes on these memory-laden monsters back at CES 2011, but now Lexar's pro-grade SDXC cards are officially available for purchase. The 128 GB card is an industry first and checks in at $329.99. The smaller -- but still rather spacious -- 64 GB card costs $200.
