I purchased a pair of these cards back in July 2009 for my Sony PMW-EX1, full-size HD Camera. I used them with an MxR Adapter and they worked wonderfully for recording hours upon hours of documentary footage. At the end April this year Digital SLR Cameras were becoming quite affordable and versatile. I purchased a Canon T2i and two more of the Transcend 16gb Class 6 cards. I was on my way to the Middle East to record a graduation and would eventually visit London.
Using the Canon T2i indoors was fine, it would of course overheat if used constantly for over 40 minutes. I shot outside one day and let the camera rest every once and awhile. It was hot out. When I finally finished shooting my camera turned off by itself. I learned the memory card had fried.
I returned back to the states and brought it to professional specialists who were unable to read the card, even through using a linux machine. I continued using my remaining cards to shoot, but began seeing overheating warnings after 30 minutes of shooting, mostly indoors.
Today I was testing out my cards and one of them would report an error after recording 2 minutes on my Sony PMW-EX1. I have a feeling these cards have low life-span and with the combination of heat and new technology, you may end up losing thousands of memories in a FLASH. Pun intended.
I would recommend spending more to save your data and back up CONSTANTLY.
