Lexar has announced plans to drop what will be the world’s largest A2 microSD card here in late-October, which is good news for Android users looking to maximize their footage and photo storage going forward.


Let’s look at the new 512GB Lexar High-Performance 633x microSDXC UHS-I card and how it can help aspiring Android smartphone filmmakers (and help out with your  action cameras and drones as well).
