Professional CompactFlash storage for high-speed

The SanDisk Extreme Pro 64GB CompactFlash card delivers read speeds up to 160MB/s and write speeds up to 150MB/s. It carries a UDMA 7 speed class rating and a VPG-65 video performance guarantee for sustained 65MB/s recording. Capacities in the series range from 16GB to 256GB.

VPG-65 rating enables cinema-quality 4K

The guaranteed minimum sustained write speed of 65MB/s prevents dropped frames during high-bitrate recording. Faster shot-to-shot performance reduces buffer clearing time between bursts. The card resists extreme temperatures and shock for reliable operation in demanding environments.

Verify your camera or recorder accepts

Check that the device supports the CompactFlash form factor and can utilise UDMA 7 transfer modes. Confirm the maximum card capacity the firmware recognises. Ensure the card slot and controller can sustain the required write throughput for your chosen video format.

Questions about this item

Does the card need any firmware updates or periodic reformatting to maintain its 150MB/s write speed?

No firmware updates are required; the card delivers up to 150MB/s write speed out of the box and maintains performance with normal use.

What stops me from recording 4K video continuously at the full 150MB/s write speed?

The VPG-65 rating guarantees a minimum sustained write speed of 65MB/s, which is the limit for uninterrupted 4K capture.

How much heat or power draw should I expect when the card runs at 160MB/s read speed all day?

The card operates within standard CompactFlash power limits and is rated for extreme temperatures, so heat and power stay low during extended reads.
