The title of the review speaks for itself. I ran a series of tests at different file sizes and depending on the file size, this Centon card averaged 10-40% faster write times than the Sandisk Extreme SDXC UHS-I 64GB 45MB/s card currently listed on Revain .com for $54.99 is available. I noticed a typo in the Revain specification. The card is listed at 80MB/s read, 20MB/s write. This is incorrect, the product packaging claims 105MB/s read and 50MB/s write. With the help of Centon I was able to increase the write speed to 50MB/s so I can verify if that's the case. My much more expensive Sandisk card could barely write 40 MB/s. The card worked great in my Lexar Pro high speed SD card reader and worked just as well in my Canon 6D camera with no formatting required, just worked right out of the box. even with long lines. Will this card stand the test of time? I can't say for sure as I only had the card for a short time. But so far it's faster than the competition, ridiculously cheaper, and works great on both my computer and camera. Sounds like I should try if you're on the fence.
