Pros & Cons
👍 Pros
- 5,000-hour endurance rating means the card is built to handle the constant write cycles of always-on dash cam and security camera recording.
- 256GB capacity provides ample storage before the camera needs to loop-overwrite older footage.
- Bundle includes both an SD adapter and a USB microSD card reader for easy file transfer to a computer.
- Class 10 speed rating ensures reliable Full HD 1080p recording without dropped frames.
- Broad compatibility with any device that accepts microSDXC cards, not limited to Garmin dash cams.
👎 Cons
- Class 10 speed may not be sufficient for cameras that record in 4K, which typically require UHS Speed Class 3 (U3) or higher.
- The included Everything But Stromboli card reader is a third-party accessory and may not match the build quality of the SanDisk card itself.
- High-endurance cards are more expensive per gigabyte than standard microSD cards, which matters if you do not need continuous recording durability.
- No application performance class (A1/A2) rating, so this card is not optimized for use as app storage on smartphones or tablets.
Frequently Asked Questions
How many hours of dash cam footage can this 256GB card hold?
SanDisk rates this card for up to 5,000 hours of Full HD (1080p) video recording endurance over its lifetime. Actual storage at any given time depends on your camera's recording bitrate, but 256GB typically holds many hours of continuous footage before looping.
Is this card compatible with dash cams other than Garmin?
Yes. It works with any dash cam or security camera that accepts microSDXC cards. The listing specifically mentions Garmin Mini, 56, and 66W, but compatibility extends to most devices with a microSD slot.

High-endurance cards are built with more durable memory cells that can withstand continuous write-and-overwrite cycles. Regular cards may fail prematurely when used in always-on recording applications like dash cams and security cameras.
Does this bundle include an SD card adapter?
Yes. The bundle includes the 256GB SanDisk High Endurance microSDXC card, a full-size SD card adapter, and an Everything But Stromboli microSD card reader.
