I was surprised to find this card for the same price as the Extreme Pro 95MB/s that had been available for a while. Almost double the read speed for the same price? Awesome! Not so fast there...

If you read the fine print on SanDisk's website or the product packaging you'll see that it requires proprietary technology to achieve the full 170MB/s read. Otherwise it maxes out at around standard UHS-I speeds of 90MB/s read, 80MB/s write. (It's called a standard for a reason.)

At first I thought my laptop's integrated card reader just wasn't up to par so I tried an external one, same results. It seems the only device capable of achieving these speeds is SanDisk's own USB 3.0 card reader, and other certified/participating devices (which so far includes nothing else). Normally I'd be upset about this but, at the time of writing, this model is almost the exact same price as the 95MB/s model, only a few cents higher. So I can't really complain, it's not like I was swindled out of more money, it's basically the same price, with the potential ability to read and write faster should you purchase their USB card reader. I'm giving it three stars because it is misleading to boldly print 170MB/s, when that's not achievable by 99% of customers. Otherwise, so far it seems like a fine card, as long as it doesn't suddenly die I may bump it up to 4 stars in the future.
