Gigastone SD Card 128GB
Score: 71/100Rankings
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.
The Gigastone 128 GB SDXC card offers a solid capacity and includes a convenient USB-C reader, backed by a 5-year data-recovery warranty. Its performance is limited by the lack of waterproofing and unspecified write speeds, making it less ideal for demanding 4K recording. Best suited for casual photographers needing extra storage and a handy reader.
