SanDisk High Endurance microSDXC 64GB + SD Adapter — for Dash Cams & Home Monitoring
The SanDisk High Endurance microSDXC 64GB card is built for continuous loop recording, the kind a dash cam or home security camera does around the clock, writing over old footage as it fills up. At 64GB, SanDisk rates it for up to 5,000 hours of Full HD recording, roughly double the 32GB card in the same line, since endurance rating scales with capacity rather than staying fixed. It delivers sequential read speeds up to 100MB/s and write speeds up to 40MB/s, with a Class 10, U3, V30 speed rating sufficient for Full HD or 4K footage. The card operates across -13°F to 185°F (-25°C to 85°C), holding up in a hot car dashboard or an outdoor camera housing exposed to the elements. A full-size SD adapter is included, and a 2-year limited warranty backs the card, which is also built to resist water, shock, and X-ray exposure.
Key Features
- Rated for up to 5,000 hours of Full HD recording, built specifically for continuous loop recording rather than occasional use
- Sequential read speeds up to 100MB/s and write speeds up to 40MB/s, sufficient for Full HD or 4K video capture
- Class 10, U3, V30 speed rating, meeting the requirements for smooth continuous video recording
- Wide operating temperature range from -13°F to 185°F, suited to a dash cam left in a hot car or an outdoor security camera
- Includes a full-size SD adapter, so the card works in both microSD devices and standard SD card readers

Best Suited For
- Dash cam owners who want longer recording cycles, since 64GB roughly doubles the recording hours of the 32GB version before older footage needs overwriting
- Home security and CCTV installations running 24/7, where the card is expected to write and overwrite footage continuously for months at a time
- Buyers who found a 32GB card fills up too quickly, since the extra capacity here reduces how often footage needs backing up or the loop cycle resets
Recommended Action: If your camera or dash cam records at higher resolutions or frame rates, consider the endurance rating drops for 4K footage compared to Full HD, so budget for a larger capacity if you need longer continuous coverage.
