Overview

The SanDisk Extreme CompactFlash 16GB memory card is designed for photographers and videographers who need dependable storage in cameras that use the CompactFlash format. With read speeds up to 60MB/s (rated at 400x), the card supports efficient file transfers when offloading images and video to a computer. SanDisk's proprietary Power Core Controller and Enhanced Super-Parallel Processing (ESP) technology work together to push the card's throughput, making it a capable option for capturing HD video on Class 6 camcorders and high-resolution stills on compatible DSLRs.

Durability is a notable strength of this card. Built-in shock protection helps it withstand bumps and drops that can occur in the field, while an internal RTV silicone coating provides a layer of defense against moisture and humidity. This makes the card a reasonable choice for outdoor and travel photography where conditions are less than ideal. At 16GB, the capacity is limited by modern standards, so it is best suited as a secondary card, for shorter sessions, or for photographers who transfer files frequently throughout a shoot.
