I have had a slow (80MB/s) 128GB microSDXC card for years now. It was in my Galaxy S5, Note Edge, my tablet, and then found it's way to my Moto Z Force. It was fine for general usage but I never loaded apps onto it as they would always take forever to load. But the card filled up with music and photos so I needed an upgrade. I thought about getting the 200GB SanDisk card but I wanted something that was faster. Google Music would sometimes stutter when loading it's buffer of songs from my memory card and I grew tired of that. So I picked this up. It's faster than my older card (by 15MB/s) and stores twice as much. The price was a little high but well worth it. Now my phone has 256GB of storage (238GB of formatted, actual storage), Google Music doesn't stutter anymore, and I won't have to worry about filling this up for at least another 3 years. Anyone with a smartphone (that has a microSDXC slot) should pick one of these up. The card costs the same as upgrading from a phone with 32GB of storage to 128GB, you might as well go with the less expensive phone, buy the card, and get more storage. I can't comment on how this would perform when being used with a digital camera but it's fast enough to store shots with my phone (24.1MP RAW) and to record 1080p 60fps h.264 video, 720p 120fps h.264 video, and 4K 30fps video without any frames being dropped or needing to buffer. So it should definitely serve the purpose for a point-and-shoot camera or 4K camcorder.
