Amazon Basics 1TB microSDXC
Score: 79/100
SanDisk Extreme PRO 256GB
Score: 100/100Rankings
The SanDisk 256 GB Extreme PRO SDXC UHS-I offers top-tier read/write performance (200 / 140 MB/s) and rugged protection, making it a strong choice for 4K creators. Its UHS-I bus limits it on cameras that can exploit UHS-II bandwidth, and some users report speed variance with cheaper readers.
The Amazon Basics 1 TB microSDXC delivers premium-class U3/V30 speeds, robust IPX6 durability and A2 app performance at a budget price, making it suitable for 4K video, Android app storage and a wide range of devices. It includes a full-size SD adapter but actual usable space is reduced after formatting and it isn't compatible with the Nintendo Switch 2.
