Built for continuous video recording

The Samsung PRO Endurance is a 128 GB microSDXC card rated for up to 70,080 hours of Full HD recording at 26 Mbps. It targets installers and owners of dash cams, CCTV systems or body cams that write video streams around the clock.

Suits always-on cameras; not for burst photography

This card fits devices that need steady, sustained write performance rather than peak burst speeds. Photographers who rely on rapid sequential RAW capture or users who need maximum read throughput for app loading should look at something else.

40 MB/s sustained write speed

The 40 MB/s write rating is the single figure that decides if the card matches a recorder’s bitrate. At 26 Mbps (3.25 MB/s) it provides ample headroom for Full HD and 4K streams, but higher-bitrate codecs may exceed it.
