Professional storage for DSLR and HD video

The SanDisk Extreme CompactFlash card delivers 64GB of capacity for high-resolution images and Full HD 1080p footage. It targets photographers and videographers who need reliable media for demanding shooting sessions. The card carries a Video Performance Guarantee of 20MB/s minimum sustained write speed. Buyers who need larger capacities or faster sustained write rates for higher-bitrate codecs should look elsewhere.

UDMA 5 CompactFlash build and workflow

The card uses the CompactFlash form factor with UDMA 5 compliance for broad compatibility with professional camera bodies and card readers. Its solid-state construction has no moving parts, helping it withstand the vibration and temperature shifts common in field work. The 400x rating and 60MB/s maximum read speed support quick offloading to a workstation. Users whose devices only accept SD media cannot use this card.

Thermals noise and power in normal use

As a solid-state memory card it generates no audible noise and runs cool during typical photo bursts and 1080p recording. Power draw is negligible and supplied entirely by the host device, so no external power is required. The 85MB/s maximum write speed and 120MB/s maximum transfer speed keep buffer clearing fast without thermal throttling. Extended high-bitrate recording beyond the guaranteed 20MB/s sustained rate may increase heat.
