SanDisk SDSQQNR-256G 256GB High Endurance microSDXC Card

The SanDisk SDSQQNR-256G High Endurance microSDXC card is purpose-built for devices that record video continuously, such as dash cams and home security cameras. Unlike standard memory cards that can degrade quickly under constant write-and-overwrite cycles, this card is engineered to handle up to 20,000 hours of Full HD (1080p) recording. It carries C10, U3, and V30 speed class ratings, meaning it maintains the sustained write speeds necessary for both Full HD and 4K UHD video capture on compatible devices.

Durability is a core strength of this card. SanDisk has designed and tested it to be temperature proof, waterproof, shockproof, humidity proof, and magnet proof — essential qualities for cards installed in vehicles or outdoor cameras where environmental conditions are unpredictable. The 256GB capacity provides a generous recording buffer, reducing how frequently loop recording overwrites older footage and giving users more historical footage to review when needed. With read speeds up to 100MB/s, transferring files to a computer for review is straightforward. For anyone running a dash cam or home monitoring system that demands reliable, uninterrupted recording around the clock, this high-endurance card is a practical and dependable storage solution.
