Samsung 128GB Micro-SD EVO+ Class 10
Samsung's new EVO+ Class 10 Micro-SD cards offer the best speed, reliability and performance out of all of their SD cards. Now that the Galaxy S7 and Galaxy S7 Edge have a micro-SD slot again, users will want one. The regular EVO can be found for under $50, but the EVO+ is the faster and best experience, especially while recording amazing video with the new Dual Pixel camera on the Galaxy S7. They're overpriced on Samsung's website, so get one today from Amazon.
