I was looking for a very fast card for my Canon 7D and looking at the website of Rob Galbraith that compares the performance of CF and SD cards, I found this map which is quite far the fastest on the market currently. In reading, it is even estimated at 129 mb / s USB3, almost 50% faster than its best competitor. I did my own tests, I set about to unload 6mn30 17 GB of Raw and Jpeg files from my Canon 7D via an express card adapter and even USB2, I put 12 minutes while I never had took less than 16 to 17 minutes with my Transcend 600x cards. I did some burst tests on the SLR, everything works perfectly. Rob Galbraith also measured 64 shots in 30 seconds on the 7D, with record raw + JPEG simultaneously. Something for me for my sports photos, football in particular. The 32GB will allow me to photograph an entire game without changing raw card. It is also very convenient when traveling to avoid manipulation and risk of damage to pine reflex that are fragile parts of the compact flash system. The card comes in a nice case with a manual and a code that lets you download Lexar Image Rescue 4 that recovers pictures when clearing or even formatting the card by mistake. A must for a long time, all the operator does not reflex the power of the UDMA7 standard, the power is still restrained
