32GB CompactFlash for DSLR cameras

The SanDisk Extreme CFXSB-032G-G46 is a 32GB CompactFlash card built for mid-range to high-end DSLR cameras and HD camcorders. It delivers read speeds up to 120MB/s and write speeds up to 85MB/s. The card carries a VPG-20 rating that guarantees a minimum sustained write speed of 20MB/s for Full HD 1080p video recording. UDMA 7 support enables fast burst-mode shooting and RAW plus JPEG capture.

UDMA 7 interface and rugged card design

The CompactFlash form factor fits standard CF slots found in professional camera bodies and external card readers. UDMA 7 compatibility ensures the card can sustain its rated transfer speeds when paired with a supporting host device. The physical design is made to withstand regular insertion cycles in demanding shooting environments. Fast transfer rates up to 120MB/s help move large RAW files and video clips to a workstation quickly.

Check your camera slot and speed requirements

Before ordering, verify that your camera or recorder accepts full-size CompactFlash cards and supports UDMA 7 to reach the advertised performance. Confirm that a minimum sustained write speed of 20MB/s meets your video recording needs. The 32GB capacity suits moderate shooting sessions; longer projects or higher bit-rate formats may require larger cards from the 64GB or 128GB options.
