Silicon Power 128GB Micro SD Card
Score: 77/100
Lexar E-Series 256GB
Score: 81/100Rankings
Lexar's 256 GB E-Series microSDXC provides up to 100 MB/s read and 140 MB/s write speeds, IPX7 waterproofing and a broad compatibility range across smartphones, tablets and action cameras. However, its UHS-I performance cannot exploit the higher speeds of UHS-II devices, and some variants lack detailed temperature specs. It's a solid choice for mobile and action-camera users seeking rugged storage.
Silicon Power's 128 GB microSDXC delivers solid read/write speeds and A1 app performance, packaged in a waterproof, dust-resistant design with a generous 5-year warranty. Its lack of shockproof rating and limited sustained write speed may restrict demanding 4K workflows. Suitable for mobile creators and drone users who value durability and app speed over top-tier sequential performance.
