Extreme PRO CompactFlash Memory Card - up to 160 MB/s read speed, 64GB

SanDisk Extreme Pro CompactFlash (160 MB/s) — Pro-Grade Storage for High-Volume Commercial Shooters

The gist: Commercial photographers and videographers working with CF-slot professional bodies get the fastest, most reliable CompactFlash option on the market — backed by a lifetime warranty and real-world speeds that match the rated specs.

• 158 MB/s real-world read speed: Camera Memory Speed benchmarks confirmed 158.3 MB/s read and 147.8 MB/s write — the kind of throughput that clears large RAW burst sequences quickly between shots during a fast-paced studio day.
• VPG-65 sustained video write: A guaranteed minimum 65 MB/s sustained write speed ensures 4K and Full HD video streams stay clean — no paused recording mid-client-shoot.
• UDMA-7 interface: The fastest CF protocol supported by professional Canon and other legacy bodies, maximizing the available bus bandwidth in cameras that support it.
• Lifetime warranty: SanDisk backs the Extreme Pro line with a lifetime guarantee — one less consumable to budget for replacement over time.

Camera Memory Speed’s real-world Canon 5Ds testing showed 99.9 MB/s write speeds — confirming the card is fast enough to stay ahead of the camera buffer even during high-speed burst commercial portrait sessions.

Best for: Commercial photographers using Canon 1D X, 5D Mark III/IV, or legacy video cameras with CF slots who need maximum performance and reliability. Skip it if: your workflow is on a modern camera body — CF cards are a legacy format replaced by CFexpress and SD in current professional cameras. Check the current price before buying — price varies by capacity.
