SanDisk Extreme PRO 512GB CFexpress Type-B - High-Speed 4K Ready

In this review the SanDisk Extreme PRO 512GB CFexpress Type-B card is examined for professional shooters and advanced hobbyists who need sustained high throughput for RAW 4K video and burst photography. The bottom line: this card delivers the kind of reliable, sustained performance that makes high-frame-rate capture and long RAW video takes practical. Tested in compatible cameras it showed consistently fast transfers and stable write performance, making it a sensible choice when the primary concern is speed and long recording runs.

Key Features

• Up to 1700MB/s read: Very fast read speeds make offloading large 4K files to a workstation noticeably quicker, reducing downtime between shoots.
• Up to 1400MB/s write: High sustained write capability helps maintain continuous RAW or high-bitrate 4K recording without dropped frames on supported cameras.
• 512GB capacity: Generous capacity suits long recording sessions and high-volume burst shooting without frequent card swaps.
• Backwards compatibility: Works with select XQD cameras, offering an upgrade path for users with older bodies that support the format.
• RescuePRO Deluxe included: Data recovery software is supplied for download, giving added assurance in case of accidental deletion or corruption.

Who It's For

The SanDisk Extreme PRO CFexpress Type-B 512GB is aimed at professional photographers, cinematographers and serious enthusiasts who record sustained high-bitrate 4K or shoot extended RAW bursts. Its combination of capacity and sustained write performance is most valuable when long continuous recording runs or large buffer clears are routine.

Casual users or those with basic SD-only cameras should look elsewhere for lower-cost cards, since this card targets high-performance workflows and is most cost-effective when paired with cameras that can fully utilize the speed.
