SanDisk Ultra Plus 128GB
Score: 75/100Rankings
The SanDisk Ultra Plus 128 GB SDXC UHS-I card offers reliable storage for photos, Full HD and entry-level 4K video, with decent read speeds and robust durability. Its A1 app rating and 10-year warranty make it a solid budget choice, though write speeds and UHS-I limits keep it out of the professional tier.
The Amazon Basics 128 GB microSDXC offers high-performance U3, A2 and V30 ratings at a budget-friendly price, with rugged IPX6 waterproofing and a full-size SD adapter. It's well suited for action cameras, drones and Android devices, though the lowest-capacity models can suffer slower writes and it isn't compatible with the Nintendo Switch 2.
