SanDisk High Endurance 512GB microSDXC Memory Card – SD Adapter Included

High Endurance Rating

Up to 40,000 Hours of Recording

Continuous video recording is the hardest workload a memory card faces — the same cells are written and rewritten thousands of times. SanDisk’s High Endurance line is engineered specifically for this write-intensive cycle, and the 512GB capacity is rated for up to 40,000 hours of Full HD recording before wear becomes a factor. For a dash cam recording your daily commute or a security camera running around the clock, that translates to years of dependable loop recording — the footage you need is there when an incident actually happens, which is the entire point of the card.

V30 / U3 Speed Class

Smooth 4K and Full HD Capture

The card runs on the UHS-I bus with sequential read speeds up to 100MB/s and write speeds up to 40MB/s. More important for video work is the guaranteed floor: the V30 and U3 ratings certify that sustained write speed never drops below 30MB/s, which is what keeps 4K and Full HD recording free of dropped frames and corrupted segments. The 100MB/s read speed also means that when you do need to pull an hour of footage off the card, the transfer is quick.

Built for Harsh Conditions

Heat, Cold, Water, Shock, X-Ray

A dash cam card bakes on a dashboard in summer and freezes overnight in winter. The High Endurance card is rated for operation from −25°C to 85°C and storage from −40°C to 85°C, and it is water proof, shock proof and X-ray proof. The included full-size SD adapter (with write-protect switch) lets the same card work in cameras, laptops and card readers that take full-size SD.

Right choice if you…

✔ Run a dash cam, home security camera or CCTV system that records continuously
✔ Have worn out standard microSD cards with loop recording before
✔ Record in Full HD or 4K and need the V30/U3 sustained-write guarantee
✔ Need a card that survives dashboard heat and winter cold
✔ Want the SD adapter in the box for full-size SD devices

Look elsewhere if you…

✖ Shoot burst photography or 8K video — the Extreme PRO line has faster peak writes
✖ Need A2 app performance for running phone apps from the card
✖ Mostly transfer large files and want maximum read speed over endurance

Frequently Asked Questions

Is the 512GB High Endurance card right for my dash cam?

Yes — this is exactly what the High Endurance line is designed for. The 512GB capacity is rated for up to 40,000 hours of Full HD recording, and the V30/U3 rating guarantees the sustained write speed that continuous loop recording needs. Check your dash cam’s maximum supported capacity in its manual before choosing a size.

What is the difference between High Endurance and SanDisk Ultra or Extreme cards?

Ultra and Extreme cards are optimised for peak speed — photos, app loading, file transfers. High Endurance is optimised for write cycles: it tolerates the constant overwrite pattern of dash cams and security cameras that wears standard cards out. If the card will live in a device that records around the clock, High Endurance is the right line.

Does it work in security cameras and CCTV systems?

Yes. Any security camera, home monitoring camera or CCTV recorder that accepts a microSDXC card can use it, and the included full-size SD adapter covers devices with a standard SD slot.

How many days of footage does it hold?

As a rule of thumb in Full HD (1080p at typical dash cam bitrates), each 8GB stores roughly one hour of footage — so the 512GB card holds in the region of 64 hours before the loop overwrites the oldest clips. Lower resolutions stretch this considerably.

Yes. Brand new SanDisk High Endurance 512GB in original sealed retail packaging, covered by the 2-year SanDisk manufacturer warranty, dispatched from our UK warehouse with tracked delivery.
