Best CFexpress Type B Card for Canon Cinema EOS C500 Mark II
The Canon Cinema EOS C500 Mark II is a 5.9K powerhouse, but its internal Cinema RAW Light recording demands storage that can handle massive data rates without breaking a sweat. I’ve seen many shooters pick cards based on “peak” speeds, only to face dropped frames during a critical take because the sustained speed plummeted. To keep your production running smoothly, you need media that prioritizes thermal management and consistent write performance. Our top pick, the Delkin Devices Black, is specifically engineered for these demanding cinema workflows.

Best CFexpress Type B Card for Canon Cinema EOS C500 Mark II: Detailed Reviews
Delkin Devices Black CFexpress Type B View on Amazon View on B&H
In the world of cinema storage, “sustained speed” is the only metric that truly matters, and the Delkin Devices Black series is the undisputed champion. While other cards boast high burst speeds, the Delkin Black maintains a minimum sustained write speed of 1530 MB/s, which is overkill for the C500 Mark II’s 2.1Gbps 5.9K RAW bitrates—and that’s exactly what you want. I personally rely on these because of their ruggedized design; they are serialized and come with a “48-hour replacement guarantee,” which provides immense peace of mind on professional sets. The thermal management is exceptional, preventing the card from throttling even during long interviews in warm environments. While it carries a premium price tag, the reliability is worth every penny for professional owner-operators. The only downside is that they are harder to find in local retail shops compared to SanDisk.

ProGrade Digital CFexpress Type B Gold View on Amazon View on B&H
The ProGrade Digital Gold series hits the sweet spot for the C500 Mark II user who needs massive capacity without the “Black” series price. With a maximum read speed of 1700 MB/s and write speeds that comfortably handle the C500’s XF-AVC and Cinema RAW Light modes, it’s a workhorse card. I’ve used ProGrade media for years, and their “Refresh Pro” software is a hidden gem, allowing you to monitor the health of your card and deep-clean the flash memory to keep it performing like new. This is particularly useful for the C500 II, as the high data throughput can wear down cheaper NAND flash over time. While the sustained write speeds aren’t quite as high as the Delkin Black or ProGrade’s own Cobalt series, it remains incredibly stable for 4K and 5.9K production. It’s the best value because you get professional-grade controller technology at a consumer-friendly price point.

Lexar Professional CFexpress Type B Silver View on Amazon View on B&H
If you’ve just invested in the C500 Mark II body and are feeling the pinch, the Lexar Silver series is a respectable entry point. It offers surprising speed for its price, easily handling the camera’s XF-AVC 4K Intra recording formats. While it is advertised with high write speeds, it doesn’t have the same robust thermal shielding as the more expensive cards on this list. For short takes and documentary-style shooting where you aren’t rolling for 60 minutes straight in RAW, it performs admirably. I would caution against using this for high-budget commercial work where the camera is constantly rolling at 5.9K, as you may eventually hit a buffer limit. However, for most users shooting 10-bit 4:2:2, this card is far more capable than its price suggests. It’s a great way to populate both slots of your C500 II without spending a fortune, giving you a safe backup for secondary recordings.

Angelbird AV PRO CFexpress B MK2 View on Amazon View on B&H
Angelbird has built a reputation for making cards that are essentially “mini SSDs,” and the AV PRO MK2 is no exception. Designed in Austria, these cards feature “Stable Stream” technology, which ensures that the write performance doesn’t fluctuate throughout the entire capacity of the card—meaning your 1000th gigabyte is recorded just as reliably as the first. This is crucial for the C500 Mark II when shooting 5.9K RAW, as the data volume is massive. I find the build quality of Angelbird cards to be top-tier; they feel dense and dissipate heat better than almost any other card I’ve tested. They also offer high capacities (up to 4TB), which is a godsend for long shoot days where you don’t want to be constantly swapping media. It’s an investment, but for a camera as capable as the C500 II, it’s the kind of media that ensures the camera is never the bottleneck in your creative process.

SanDisk Extreme PRO CFexpress Type B View on Amazon View on B&H
The SanDisk Extreme PRO is the card you’ll find in almost every rental house kit for a reason: it’s predictable and widely compatible. For the C500 Mark II, the SanDisk offers reliable 1700 MB/s read and 1400 MB/s write speeds. You’ll notice that while it doesn’t have the “cinema-first” branding of Delkin or Angelbird, it handles the camera’s high-bitrate XF-AVC modes with zero issues. I’ve found that these cards can run a bit hotter than the Angelbird MK2 during extended 5.9K recording, but the C500 II’s internal fan does a great job of keeping the card slots cool. It’s a solid “safe” choice, and because they are so common, you can pick one up at almost any electronics store if you find yourself short on media in the middle of a shoot. It doesn’t excel in any one specific area, but it does everything well enough to be a staple in your kit bag.

Frequently Asked Questions
How much 5.9K RAW footage fits on a 512GB card?
On the Canon C500 Mark II, 5.9K Cinema RAW Light at 23.98 fps produces a bitrate of approximately 2.1 Gbps. This translates to roughly 15-16 GB of data per minute of footage. Therefore, a 512GB card will give you approximately 30 to 32 minutes of recording time. For full-day shoots, I highly recommend stepping up to 1TB or 2TB cards to reduce the frequency of offloading to your DIT or laptop.
Does the C500 Mark II require VPG-400 certified cards?
While the C500 Mark II does not strictly “require” the Video Performance Guarantee (VPG-400) certification to function, using a card that meets this standard is highly beneficial. VPG-400 ensures that the card will never drop below a 400 MB/s write speed. Since the C500 II’s highest bitrates are well within this margin, a VPG-400 card (like the newer Lexar Gold or ProGrade Cobalt) offers an extra layer of safety for high-end production.
Can I use XQD cards in the C500 Mark II?
No, the Canon C500 Mark II is designed specifically for CFexpress Type B media. While CFexpress and XQD share the same physical form factor, the internal interface is different (NVMe vs. PCIe 2.0). The C500 II’s slots will not recognize XQD cards. This is a common point of confusion for those upgrading from the C300 Mark II or older Sony cameras, so ensure you invest in the correct Type B media.
Why do the cards get so hot during recording?
CFexpress Type B cards are essentially high-performance NVMe SSDs shrunk down to a tiny size. When writing data at 2Gbps, they generate a significant amount of heat. The C500 Mark II features an internal cooling system that helps pull heat away from the sensor and the card slots, but the cards themselves will still be hot to the touch when you eject them. This is normal behavior for the format.
What is the best way to offload these cards quickly?
To get the most out of your high-speed CFexpress cards, you need a reader that matches their speed. Using a standard USB 3.0 reader will bottleneck your transfer to about 100-200 MB/s. I recommend using a USB 3.2 Gen 2×2 reader (20 Gbps) or, even better, a Thunderbolt 3/4 card reader. This allows you to offload a full 512GB card in just a few minutes, which is essential for busy sets.
Final Verdict
For professional cinematographers shooting 5.9K Cinema RAW Light, the Delkin Devices Black is the clear choice for its uncompromising reliability. If you primarily work in XF-AVC for corporate or documentary projects, the ProGrade Digital Gold offers the best balance of speed and price. For those on a tight budget who need to fill two slots, the Lexar Silver provides capable performance for 4K workflows without the premium cost. Always prioritize sustained speed over advertised “peak” numbers.
