Overview
Samsung designed the PRO Endurance card for devices that record nonstop, such as dash cams and home security cameras, and rates it for very long Full HD recording time. Protection against water, magnets, X-rays, drops and temperature extremes is built in.
Endurance is what matters in a dash cam, where constant rewriting wears out ordinary cards quickly. The small capacity means loop recording overwrites footage sooner, so save important clips promptly.
Who it's for
Drivers and homeowners running cameras that record all day. Camera and drone users after write speed should choose a faster rated card.

Performance notes
Endurance comes from flash rated for constant overwriting, which is how dash and security cameras use a card. Write speed is modest but enough for Full HD streams. Capacity sets how much footage is kept before the oldest is overwritten.
