FAQ
What is the actual storage capacity available on this 256 GB SDXC card?
The SanDisk Extreme PRO SDXC card provides 256 GB of storage capacity, which offers approximately 238 GB of usable space after formatting. This substantial capacity allows photographers to store thousands of high-resolution RAW images or hours of full HD video footage without needing to change cards frequently during shooting sessions.
How does the Class 10/UHS-I (U3) rating affect camera performance?
The Class 10 rating guarantees minimum write speeds of 10 MB/s, while the UHS-I U3 classification ensures minimum write speeds of 30 MB/s. This combination enables smooth recording of high-bitrate video formats and supports continuous burst shooting modes in modern cameras without buffer delays, making it ideal for action photography and professional videography.
What does the V30 video speed class mean for video recording?
The V30 video speed class certification indicates the card maintains a minimum sustained write speed of 30 MB/s, which is sufficient for recording full HD 1080p video at high bitrates. This ensures consistent performance during extended video recording sessions without dropped frames or recording interruptions, making the card reliable for professional video production.
Is this SDXC card compatible with older SDHC card slots?
Yes, the SanDisk Extreme PRO SDXC card maintains backward compatibility with SDHC and SD card slots due to its identical physical dimensions and interface. However, devices must support the SDXC specification to recognize the full 256 GB capacity. In SDHC-only devices, the card may not be recognized or may show reduced capacity depending on the device's firmware.
What types of cameras and devices work best with this memory card?
This card performs optimally with modern DSLR and mirrorless cameras, professional video cameras, drones with camera capabilities, and action cameras that support UHS-I interfaces. It's particularly well-suited for cameras that feature high-resolution sensors, 4K video recording capabilities, or high-speed continuous shooting modes that demand fast write speeds and substantial storage capacity.
How does the 200 MB/s read speed benefit photography workflows?
The 200 MB/s maximum read speed enables rapid transfer of image and video files from the card to a computer or storage device. This significantly reduces downtime during post-production workflows, allowing photographers and videographers to offload large shooting sessions quickly. When using compatible card readers, this speed advantage becomes particularly noticeable when transferring hundreds of high-resolution images or lengthy video files.
