High Endurance microSDXC card for continuous

The SanDisk High Endurance microSDXC card is built for dash cams and home monitoring systems that write video around the clock. Its 64 GB capacity and UHS-I interface let it slot into any device that accepts microSDXC media. The card targets users who need reliable, long-duration capture without frequent swaps.

UHS-I bus limits sustained write throughput

The UHS-I interface caps sequential write performance at 40 MB/s, which is sufficient for Full HD and 4K streams but cannot absorb higher-bitrate formats or simultaneous multi-camera feeds. Read speeds reach 100 MB/s for faster offloads, yet the bus ceiling remains the bottleneck during continuous recording sessions.

64 GB stores up to 5,000 hours of footage

At this capacity the card holds roughly 5,000 hours of typical dash-cam video before overwriting begins. Larger capacities up to 256 GB extend that headroom proportionally, while the 64 GB model will fill quickly under 4K recording or multi-channel setups.

Questions about this item

Which capacity should I choose for my dash cam, the 64GB or the larger 256GB version?

The 64GB card records up to 5,000 hours of footage, while the 256GB option stores more Full HD or 4K video for longer loops between overwrites.

What does the 100MB/s read speed actually deliver when I offload footage to my computer?

It lets you transfer recorded files quickly so you spend less time waiting and more time reviewing critical video evidence.

How do the UHS-I, U3, V30 and Class 10 ratings affect real-world recording?

They guarantee a minimum 30MB/s write speed, ensuring smooth 4K UHD capture without dropped frames on compatible devices.
