SanDisk 64GB Extreme CompactFlash Memory Card - Fast UDMA 7

In this review the SanDisk 64GB Extreme CompactFlash card is judged as a practical choice for photographers and videographers who need dependable speed and capacity without a premium price. The single biggest reason to buy is its consistent performance: up to 120MB/s read and up to 85MB/s write, which keeps burst shooting and file transfers moving. The card is aimed at mid-range to high-end DSLR users and HD camcorder owners who want reliable write rates and rugged construction for on-location work.

Key Features

• High read speed: Read speeds up to 120MB/s reduce transfer times when copying large RAW files to a workstation.
• Fast write performance: Write speeds up to 85MB/s support burst-mode photography so the camera buffer clears faster between sequences.
• Professional video capture: VPG-20 support ensures a sustained 20MB/s recording rate for smooth Full HD video without dropped frames.
• Durable design: The card is subjected to stress, shock, and vibration testing and includes RTV silicone coating for added protection during field use.
• Capacious storage: 64GB of space holds hundreds of RAW photos or hours of Full HD video for long shoots or events.

Who It's For

The card is best suited for photographers using mid-range to high-end DSLRs like full-frame and professional crop-sensor bodies, and for HD camcorder shooters who require sustained write rates for continuous recording. Wedding, event, and wildlife photographers will appreciate the combination of speed and capacity during long sessions.

Users who shoot very high-bitrate 4K video or need the absolute fastest modern interfaces should look elsewhere for newer card formats, but for those with CompactFlash-supporting cameras seeking value and dependable performance, this model is a strong fit.
