Compare SanDisk Extreme Pro CFexpress card capacities for speed, storage, and price. Get clear decision rules for 8K video, RAW bursts, and your budget.
Quick answer
If you shoot 8K video or long RAW bursts, choose the 512GB SanDisk Extreme Pro CFexpress card. For stills-only or occasional video, the 256GB offers the best balance of capacity and cost, while the 64GB suits budget-conscious shooters who offload frequently.
Why capacity matters more than you think
All three SanDisk Extreme Pro CFexpress cards share the same Type B interface and similar read/write speeds, so the real difference is how much footage or how many RAW frames you can capture before swapping cards. For 8K video, a single minute can consume several gigabytes, so a 64GB card may fill up in under ten minutes. That forces you to stop recording or carry multiple cards, which is fine for controlled shoots but risky for events or wildlife where you can't interrupt.
The trade-off: price per gigabyte
The 512GB card costs more upfront, but its price per gigabyte is lower than the 256GB and 64GB options. If you regularly fill cards, the larger capacity saves you money over time and reduces the number of cards you need to buy. However, if you rarely shoot more than a few gigabytes per session, the 64GB card's lower absolute price makes more sense, even if the per-GB cost is higher.
Decision rules
- If you shoot 8K video or long continuous RAW bursts: Choose the 512GB card. It provides the capacity to record extended sessions without interruption, and its per-GB cost is the lowest of the three. Check your camera's recording bitrate to estimate minutes per GB.
- If you shoot stills primarily, with occasional video: Choose the 256GB card. It offers ample space for thousands of RAW images and short video clips, balancing cost and capacity.
- If you're on a strict budget and offload frequently: Choose the 64GB card. It's the most affordable entry point into CFexpress speed, but be prepared to swap cards during long shoots. Carry at least two 64GB cards to avoid missing shots.
