Score: 82/100Rankings
Silicon Power's 128 GB microSDXC card offers near-premium UHS-I performance with up to 100 MB/s read and 80 MB/s write, rugged durability, and A2 app support, making it a budget-friendly choice for 4K video, gaming, and mobile storage. The inclusion of an SD adapter adds versatility, though some variants have slower write speeds and occasional quality control issues.
The SanDisk Ultra 32 GB microSDHC pack provides two high-speed cards with excellent 120 MB/s read performance, A1 app capability, and rugged durability, ideal for Android devices and Full HD video. Lack of a V30/U3 rating and unspecified write speeds keep it out of the 4K-video segment.
