Kingston's new Secure Digital Extended Capacity cards use the exFAT format to provide up to 128 GB of storage space. As a class 10 card it will also maintain a minimum data rate of 10 MB/s for your favorite digital device. This is perfect for your digital video camera, portable tablet, or portable video device. It could be a little overkill for your cell phone or digital camera (unless you are a professional photographer).
The new SDXC class 10 cards can be found at your favorite e-tailer at 64 GB for $49.95 and 128 GB for $114.99. This is well below Kingston's MSRP, but are very competitively priced. If I have to pick a brand when I am buying memory, I will be picking Kingston since memory is what they do.
