Hi guys, I am planning to put in a minidrive into my macbook air and it will require a microSD card for storage. I have been looking at the Sandisk family due to their speed/popularity. Unfortunately, I am now confused at their marketing of this product. I have found: Sandisk Ultra MicroSD for mobile devices (off Sandisk Webby) Sandisk Ultra MicroSD for Cameras (off Sandisk Webby) Sandisk Ultra Mobile MicroSD (off ebay stores) All these products are Class 10 and UHS1, but how do they differ from each other. The Sandisk webpages for these product are fairly similar in description. I was hoping you guys can help me out or recommend a 64 gb microSD card that is reasonably quick. The Sandisk Extreme MicroSD does not come in 64 gb.
