SanDisk 512GB Extreme PRO CFexpress Card Type B - Fast RAW Workflow

Our review of the SanDisk 512GB Extreme PRO CFexpress Card Type B finds it best suited to photographers and videographers who demand the fastest offload and sustained capture speeds for RAW and 4K workflows. The single biggest reason to consider this card is its class-leading sustained performance: SanDisk reports up to 1700MB/s read and 1400MB/s write on the 512GB model, which translates to reduced buffer times and quicker transfers to editing systems. For anyone shooting burst RAW or high-bitrate video, that speed materially improves workflow efficiency.

Key Features

• High read speed: Up to 1700MB/s read speed lets users transfer large photo and video files to a workstation more quickly, reducing wait time between shoots and edits.
• Fast write performance: Up to 1400MB/s write speed on the 512GB card supports sustained high-rate recording for RAW stills and high-bitrate video without frequent buffer stalls.
• 4K RAW support: Enables smooth RAW 4K video recording on compatible cameras, helping professionals capture high-resolution footage with minimal dropped frames.
• Backwards compatibility: The CFexpress Type B form factor can be used in select XQD cameras after a manufacturer firmware update, extending compatibility for some existing camera owners.
• RescuePRO software: Includes RescuePRO Deluxe recovery software for downloadable file recovery, offering an extra layer of data protection if files are accidentally deleted.

Who It's For

The card is ideal for professional photographers and cinematographers using CFexpress Type B-compatible cameras who need sustained high write speeds for continuous RAW bursts or long, high-bitrate video takes. It is also a good choice for hybrid shooters who move large files frequently and want to shorten transfer and backup windows.

Casual users or those with older entry-level cameras that do not support CFexpress Type B should look elsewhere; micro SDXC or standard SD cards remain a better, lower-cost option for basic photo and 1080p video use. Also confirm camera compatibility and any required firmware updates before purchasing.

Pros & Cons

Pros

• Very high read and write speeds reduce buffer and transfer times for professional workflows.
• 512GB capacity holds thousands of photos or many hours of high-bitrate footage without swapping cards.
• RescuePRO Deluxe recovery software is included to help recover accidentally deleted files.

Cons

• Some users report the card runs warm under sustained use, so heat management and camera compatibility should be considered.
