The SanDisk Ultra MicroSD Card costs $72.97. It can send data to your phone at 90 MB/s. That’s faster than most cards can. Storage sizes range from as little as 8GB to 200GB of storage. Because it’s a Class 10 MicroSD card, it’s great for storing 1080p and 4K video. That last bit is important. The Moto Z’s rear-facing camera supports 4K video recording.
