Engineered for Continuous Recording

The SanDisk MAX ENDURANCE microSDXC card delivers 128GB of storage built for home security cameras and dash cams. It is rated for up to 120,000 hours of continuous recording and re-recording. The card carries UHS-I, U3, Class 10 and V30 speed ratings to sustain high-resolution video capture. An included adapter allows use in standard SD slots.

Durability in Extreme Conditions

This card is temperature-proof, waterproof, shockproof and X-ray-proof for reliable operation in harsh environments. It protects footage against physical damage and environmental stress year after year. The robust construction supports uninterrupted recording in outdoor security or vehicle-mounted applications. No moving parts means silent operation with minimal power draw.

V30 Sustained Write Speed Guarantees 4K Capture

The V30 rating guarantees a minimum sequential write speed of 30MB/s, which is the decisive spec for 4K video recording without dropped frames. Maximum read speed reaches 100MB/s for fast footage offload, while write speed peaks at 40MB/s. Buyers who need higher sustained write throughput or larger capacities should consider other options.

Questions about this item

How do I install the SanDisk MAX ENDURANCE microSDXC card in my security camera and what step is often missed?

Insert the 128GB card into the camera's microSD slot until it clicks, then format it in the camera's settings menu before recording; skipping the in-camera format is the common mistake that causes file errors.

What maintenance or replacement should I plan for after extended recording use?

The card is engineered for up to 120,000 hours of continuous recording and re-recording; after reaching that endurance limit the memory cells can no longer reliably store new footage and the card should be replaced.

What is the first performance limit I will hit during sustained 4K video writing?

The sequential write speed caps at 40MB/s, so prolonged 4K capture is constrained by that write throughput before any other factor becomes a bottleneck.
