Description
The SanDisk Extreme CompactFlash card is engineered for mid-range to high-end DSLR cameras, offering a balanced combination of speed and durability. With a read speed of up to 120MB/s and write speeds of 85MB/s, this card utilizes the UDMA 7 interface to optimize data flow between the camera's buffer and the storage media. This ensures that high-resolution RAW images and Full HD video are captured without the bottleneck of slower storage solutions.
This product is for:
- Professional photographers using legacy DSLR systems like the Canon EOS 5D Mark II or Nikon D800 who require reliable CF media.
- Sports and wildlife photographers who rely on continuous burst mode to capture fast-moving subjects without filling the buffer prematurely.
- Videographers recording Full HD video who require a Video Performance Guarantee (VPG-20) for consistent 20MB/s recording.
- Studio technicians who need to offload large batches of RAW images quickly to maintain tight production schedules.
- Travel photographers operating in extreme environments, as the card is tested for temperature, shock, and vibration resistance.

In practical application, the UDMA 7 support allows the card to handle high-resolution RAW files without significant buffering delays. The internal SanDisk controller manages data distribution across the flash memory cells, which enhances both the longevity of the card and the integrity of the stored files. This reliability is critical for event photographers who cannot risk data loss during a shoot. The physical build includes an RTV silicone coating, providing an extra layer of protection against moisture and humidity.
When compared to the SanDisk Ultra series, the Extreme version provides significantly higher write speeds (85MB/s vs 50MB/s), making it the superior choice for action photography. While the Extreme Pro series offers even higher speeds up to 160MB/s, the Extreme series provides a more cost-effective solution for users who do not require 4K cinema-grade bitrates but still need professional-level reliability and fast offloading speeds for Full HD content.
Q&A:
- Does this card work with older cameras? Yes, but some legacy devices may require a firmware update to recognize capacities over 32GB or the UDMA 7 interface.
- What does VPG-20 mean for video? It ensures a minimum sustained write speed of 20MB/s, preventing dropped frames during Full HD video capture.
- Is a specific card reader required? To achieve the full 120MB/s transfer speed, a USB 3.0 or higher CF card reader that supports UDMA 7 is recommended.
- How durable is the card's construction? The card is designed to withstand extreme temperatures and includes internal shock protection.
- Can this card store 4K video? While it can store 4K files, the 85MB/s write speed is optimized primarily for Full HD; for high-bitrate 4K, the Extreme Pro series is generally preferred.
