They say it's good for 10,000 hours of 1920x1080 at 26Mbps to one device. I have no idea how they came to this conclusion. It comes in 32GB and 64GB. It's rated from -13 degrees to 185 degrees Fahrenheit. It's waterproof, shockproof, and x-ray resistant. A photography store with which I am familiar is taking preorders for $25 for the 32GB and $50 for the 64GB. Best of all, it comes with 1 year of access to RescuePro Deluxe, which is a real solid data recovery program, just in case.
