We know how commoditized the microSD card market is at the moment. Frankly speaking, if you need to just store things forever, a drawer full of cards might be good and cheap enough for your parents to care for. But if you're actively using them in your cameras and computers, you'll probably want to invest a little bit more. The good news is that you can get a SanDisk 400GB Extreme card for just a little cheaper than usual right now.
