SanDisk Extreme 32GB CompactFlash Card - Fast Shot-to-Shot Performance

In this review the SanDisk Extreme 32GB CompactFlash card is evaluated for photographers and videographers who need reliable burst shooting and steady HD video capture. The bottom line: this card is best for mid-range to high-end DSLR users who want fast transfer and shot-to-shot performance without paying pro-tier prices. Read speeds up to 120MB/s and write speeds up to 85MB/s make it a practical choice for burst mode, while VPG-20 support assures uninterrupted Full HD recording for compatible camcorders and DSLRs.

Key Features

• High read speed: Read speeds up to 120MB/s reduce wait time when transferring large RAW files to a computer and speed workflow.
• Fast write performance: Write speeds up to 85MB/s handle burst-mode photography and minimize buffer clearing on mid-range to high-end DSLR bodies.
• VPG-20 video support: The VPG-20 rating guarantees a sustained 20MB/s recording rate, which helps avoid dropped frames during extended Full HD recording.
• Durable construction: The card is designed and tested for stress, shock, and vibration, and includes an RTV silicone coating for extra protection in field conditions.
• Ample capacity: At 32GB the card holds hundreds of JPEGs or a mix of RAW files and HD clips for casual shoots and short projects.

Who It's For

The SanDisk Extreme 32GB CompactFlash is aimed at photographers using mid-range to high-end DSLRs and HD camcorders who need quick file transfers and dependable burst performance. It is a sensible upgrade for users of bodies like Canon and Sony models that accept CompactFlash, where faster write speeds reduce time between bursts and speed up post-shoot offloads.

Photographers who routinely record long 4K video, professionals requiring the highest sustained write rates, or users needing very large single-card capacities should consider higher-capacity or higher-end alternatives. Occasional shooters and smartphone photographers will find this overpowered for casual use.
