SanDisk Extreme 64GB CompactFlash Card

The SanDisk Extreme CompactFlash card offers 64GB of storage for DSLR cameras and HD camcorders. It delivers read speeds up to 120MB/s and write speeds up to 85MB/s. The card carries a UDMA 7 rating and a VPG-20 video performance guarantee. It suits photographers who need reliable capture for fast action and Full HD video.

Sustained write performance and VPG-20 guarantee

The VPG-20 rating ensures a minimum sustained write speed of 20MB/s for continuous Full HD 1080p recording. Write speeds up to 85MB/s support burst-mode photography and RAW plus JPEG capture without buffering delays. Read speeds up to 120MB/s accelerate post-shoot file transfers to a computer. Performance remains consistent across extended shooting sessions rather than only in short bursts.

Check camera slot and workflow requirements

Verify that your camera accepts CompactFlash media before ordering, as this card will not fit SD or CFexpress slots. Confirm that your card reader or computer interface supports UDMA 7 to achieve the stated transfer rates. The 64GB capacity suits moderate shooting sessions; users recording long 1080p events or extensive RAW bursts may require larger cards.

Questions about this item

How much power does the 64GB SanDisk Extreme CompactFlash card draw when recording continuously at 85MB/s?

CompactFlash cards are passive storage devices with no active components, so they draw negligible power from the camera and generate no measurable heat during sustained write operations at 85MB/s.

Does my camera need a UDMA 7-compatible CompactFlash slot to use this card's 120MB/s read speed?

Yes, the card uses the UDMA 7 interface; a camera or reader that supports UDMA 7 is required to achieve the rated 120MB/s read and 85MB/s write speeds.

Will this CFXSB-064G-G46 card work in an older DSLR that only supports UDMA 6?

The card is backward compatible with UDMA 6 slots, but read and write speeds will be limited to the older interface's maximum throughput.
