Built for CCTV, Dash Cams and Body Cameras
The high endurance design makes this Samsung SDXC memory card particularly suitable for security and monitoring equipment. CCTV cameras can continuously save footage without relying on a conventional consumer memory card that may not be designed for repeated writing.

It can also be used in compatible dash cameras and body cameras where recording may continue for extended periods. The 256GB capacity helps reduce the frequency of footage being overwritten while providing ample space for large video files.

Durable Storage for Demanding Conditions
The Samsung PRO Endurance is designed to withstand more than everyday storage use. It has been tested for resistance to several common environmental and physical hazards:

• Water resistance: Can withstand up to 72 hours at a depth of 1 metre under specified testing conditions
• Magnetic resistance: Resists magnetic fields up to 15,000 Gauss
• X-ray resistance: Designed to protect stored data from airport X-ray machines
• Drop resistance: Tested for drops of up to 5 metres
• Wear resistance: Tested for up to 10,000 swipes
• Operating temperature: -25 C to 85 C
• Non-operating temperature: -40 C to 85 C

These characteristics make it suitable for cameras and recording equipment exposed to changing temperatures, movement and demanding operating environments.

Fast UHS-I Performance for High Resolution Video
With read speeds of up to 100 MB/s and write speeds of up to 40 MB/s, the card is designed to handle large video files efficiently. The U3 and V30 ratings indicate that it is intended for sustained video recording workloads when used with compatible equipment.

Actual speeds depend on the host device, interface and operating conditions, but the combination of UHS-I, U3, V30 and Class 10 ratings makes this 256GB memory card a strong option for compatible Full HD and 4K recording devices.

Long Recording Endurance
The Samsung PRO Endurance 256GB is rated for up to 140,160 hours of Full HD recording under Samsung's specified test conditions. The actual recording duration will vary depending on camera settings, resolution, bitrate, available storage and other factors.

The high endurance design is especially useful where a memory card is expected to record and rewrite data continuously over long periods.

Samsung Flash Memory Technology
Samsung produces the flash memory and key components used in its memory cards in-house, supporting end-to-end control over the manufacturing process. The PRO Endurance range is designed to provide dependable storage for applications where recording reliability is more important than simply maximising general-purpose storage capacity.

For online buyers looking for a Samsung 256GB SD card for CCTV, dash cams or continuous video recording, the PRO Endurance provides a combination of capacity, sustained performance and durability.

Why Choose the Samsung PRO Endurance 256GB SD Card
The Samsung PRO Endurance 256GB is a purpose-built memory card for continuous recording applications. Its high endurance rating, 256GB capacity, V30 and U3 classifications, fast UHS-I interface and resistance to demanding conditions make it a suitable storage solution for compatible CCTV cameras, dash cams and body cameras.
