Professional Grade Video Capture

The SanDisk Extreme 128GB CompactFlash card targets photographers and videographers who need reliable high-speed storage for demanding shoots. Its VPG-20 rating guarantees a minimum sustained write speed of 20 MB/s for uninterrupted video recording. Read speeds reach up to 120 MB/s while write speeds hit 85 MB/s for rapid shot-to-shot performance.

VPG-20 Sustained Recording

The Video Performance Guarantee 20 certification changes workflow by ensuring the card never drops below 20 MB/s during continuous capture. This prevents frame drops and recording stops that ruin professional footage. The 128 GB capacity holds extensive raw image sequences or lengthy high-bitrate video clips without frequent media swaps.

Durable Design For Field Use

Rigorous stress, shock and vibration testing back the card's reliability in harsh environments. An RTV silicone coating adds physical protection against impact and vibration during transport or handheld shooting. The compact form factor measuring 0.14 x 1.68 x 1.41 inches fits standard CF slots without adding bulk to professional camera rigs.

Questions about this item

How long will the CompactFlash card last before the memory cells wear out?

The card uses 128 GB of NAND flash rated for thousands of program/erase cycles; typical photo and video workloads reach end-of-life after several years of daily heavy use.

What sustained write speed does the VPG-20 rating guarantee during long video recording?

VPG-20 certifies a minimum sustained write rate of 20 MB/s, which is the limiting factor for uninterrupted 1080p or 4K capture.

Does the card run hot or draw extra power when recording video continuously?

The RTV silicone coating and shock-tested design keep operating temperature and power draw within normal CompactFlash limits during all-day recording sessions.
