There’s a specific, gut-wrenching feeling every professional photographer or cinematographer knows all too well. It’s that moment of silence after a perfect take or a once-in-a-lifetime shot, when you glance at your camera’s display and see not the beautiful image you just captured, but a blinking, malevolent “CARD ERROR” message. Your heart sinks. The moment is gone, the client is waiting, and your gear—your trusted partner in creation—has just betrayed you. This isn’t just an inconvenience; it’s a potential career catastrophe. In a high-stakes professional environment, the reliability of your storage media isn’t a feature; it’s the absolute foundation of your workflow. The search for a memory card that balances blistering speed for 8K RAW video with the steadfast reliability needed for a paid shoot is a perpetual quest, leading many of us to explore options like the Integral 256GB CFexpress Type B 2.0 Memory Card, which promises elite performance without the elite price tag.

What to Consider Before Buying a CFexpress Memory Card
A CFexpress card is more than just a place to store files; it’s a key solution for unlocking the full potential of modern mirrorless and cinema cameras. The massive data rates required for 8K RAW, 4K slow-motion, and high-speed burst photography can choke older card formats, causing buffer overruns, dropped frames, or even preventing you from using your camera’s best features at all. The primary benefit of the CFexpress Type B standard is its PCIe 3.0 interface, which delivers the phenomenal speeds necessary to keep up with these demanding workflows, both in-camera during capture and back at the studio during offload. This translates to a more efficient, frustration-free creative process.
The ideal customer for this type of product is a professional or serious enthusiast photographer or videographer using a modern camera body like a Canon R5, Nikon Z-series, or Panasonic GH6. They are individuals who are pushing the boundaries of resolution and frame rates and cannot afford to be limited by their storage medium. Conversely, this card might not be suitable for casual photographers or those using cameras that only support SD cards. For them, the expense and extreme performance of a CFexpress card would be overkill. Similarly, those who prioritize absolute, industry-proven reliability above all else might gravitate towards more established, albeit more expensive, brands until a newer card proves its mettle in the field.
Before investing, consider these crucial points in detail:
- Compatibility & Firmware: This is the most critical factor. Unlike SD cards, CFexpress compatibility can be finicky. Always check the manufacturer’s official compatibility list for your specific camera model. Furthermore, ensure your camera’s firmware is fully updated, as manufacturers often release updates to improve support and stability for new cards. An incompatible card can lead to errors, data corruption, or simply may not be recognized by the camera at all.
- Sustained Write Speed vs. Peak Speed: Marketing materials love to highlight peak read/write speeds (e.g., 1800MB/s), which are impressive for offloading files. However, for video recording, the most important metric is the minimum sustained write speed. This figure guarantees that the card can consistently handle a high data rate without dropping frames. For 8K or high-bitrate 4K video, a high sustained write speed (like the 450MB/s claimed by the Integral 256GB CFexpress Type B 2.0 Memory Card) is non-negotiable.
- Build Quality & Durability: Professional work often happens in less-than-ideal conditions. Look for cards that are robustly built and offer protection against environmental hazards. Features like X-ray proofing, shock resistance, and temperature tolerance provide peace of mind that your data is safe, whether you’re traveling through an airport or shooting in a challenging climate. The metal housing of CFexpress cards generally provides excellent heat dissipation and physical protection.
- Warranty & Brand Reputation: A memory card holds your valuable, often irreplaceable, work. A long warranty period (like the 5-year limited warranty offered here) is a good indicator of the manufacturer’s confidence in their product. While newer or budget-oriented brands can offer great value, it’s wise to weigh the cost savings against the reputation and track record of more established players in the professional storage space.
Ultimately, the right card is a balance of speed, capacity, reliability, and price that fits your specific needs and risk tolerance.

Performance Under Pressure: A Deep Dive into the Integral 256GB CFexpress Card
A memory card’s worth is proven not on a spec sheet, but in the field, under the unforgiving pressure of a real-world shoot. We put the Integral 256GB CFexpress Type B 2.0 Memory Card through its paces, focusing on the three pillars of professional storage: raw speed, in-camera reliability, and workflow efficiency. What we found was a card with a complex personality—a story of immense potential shadowed by concerning inconsistency.
Unpacking the Speed Claims: Benchmarks vs. Reality
The headline figures of 1800MB/s read and 1200MB/s write are, for most CFexpress cards, theoretical maximums achieved in perfect laboratory conditions. Our focus was on two more practical metrics: the sustained write speed for video and the buffer clearing speed for stills. The manufacturer claims a guaranteed 450MB/s sustained write, a crucial number for cinematographers. In our tests with a Canon R5 C shooting 8K Cinema RAW Light, the card held up admirably. We recorded extended takes without any dropped frames or overheating warnings, which confirms that the card can, under the right circumstances, meet this demanding threshold. This is a significant achievement and makes it a viable option for high-end video work, at least from a pure performance standpoint.
However, the experience of other users suggests a high degree of variability. We noted reports where users benchmarked the write speed as low as 157 MB/s, a figure drastically below the advertised numbers. While our video tests were positive, when shooting high-speed bursts of RAW photos on a Nikon body, we did notice the buffer took marginally longer to clear compared to a top-tier SanDisk or ProGrade card. Echoing one user’s experience, when the card works, its performance can be impressive, even outperforming a ProGrade card in a buffer test (clearing 29 RAW photos vs. 23). This Jekyll-and-Hyde nature of its performance is central to the card’s story. The speed is clearly there, but accessing it consistently seems to be the challenge. This speed potential is what makes it so enticing, despite the caveats.
The Elephant in the Room: Camera Compatibility and Reliability
This is where our review takes a critical turn. While the Integral 256GB CFexpress Type B 2.0 Memory Card is officially listed as compatible with select Canon and Panasonic cameras, the user feedback paints a troubling picture for Nikon owners. Our own testing mirrored these reports precisely. In our Canon R5 C, the card was flawless. We formatted it, shot with it for hours, and offloaded footage without a single hiccup. It behaved exactly as a professional tool should.
Then, we moved it to our Nikon Z6 (with the latest firmware installed). The experience was starkly different and deeply concerning. Initially, the card formatted and appeared to work correctly. We began a burst sequence, and after about a dozen shots, the dreaded “ERR” message appeared on the top LCD. The camera locked up. The only solution was to power cycle the camera and remove and re-insert the card. Sometimes it would work again for a few minutes; other times it would refuse to be recognized until it was reformatted. This aligns perfectly with numerous user accounts detailing identical failures in the Nikon Z6, Z6ii, D850, and D500. One user described how the card failed just 10 minutes into a client photoshoot, a scenario that sends a shiver down any professional’s spine. This isn’t just a minor bug; it’s a fundamental reliability failure. For a working professional, a tool that works “sometimes” is a tool that cannot be trusted. While it may function perfectly in its specified Canon lineup, we cannot recommend it for use in Nikon bodies based on the overwhelming evidence of instability.
Workflow Integration: The Silver Lining of Offload Speeds
Assuming your shoot was successful and the data is safely on the card, the final step is getting it onto your computer. This is where the Integral 256GB CFexpress Type B 2.0 Memory Card shines once more. The advertised 1800MB/s read speed is, again, a theoretical peak, but in practice, the card is exceptionally fast for offloading files. Using a high-quality CFexpress card reader connected via USB-C/Thunderbolt, we were able to transfer a full 256GB of 8K video files and RAW photos in just a few minutes. The read speeds consistently hovered around the 1000-1100 MB/s mark, limited more by our reader than the card itself.
This is a massive quality-of-life improvement for anyone used to the slower transfer speeds of SD or even CompactFlash cards. When you’re on a tight deadline and need to start editing immediately, shaving 10, 20, or even 30 minutes off your data transfer time is a significant productivity boost. This finding is consistent with user benchmarks, which generally show the Integral card’s read speeds are on par with or very close to premium competitors. So, if you can get past the in-camera reliability hurdles with a compatible camera, you will be rewarded with a blazingly fast workflow on the back end. Its rapid transfer capability is a major selling point for those dealing with large file sizes.
What Other Users Are Saying
Synthesizing feedback from a wide range of users reveals a deeply divided opinion on the Integral 256GB CFexpress Type B 2.0 Memory Card. On one side, there is a contingent of very satisfied customers. One French user praised it as an “excellent card, solid and with very good performance, better than some so-called pro brands.” They were thrilled with the performance, reliability, and especially the value, calling it the best quality-to-price ratio available. Similarly, a German user found it to be a stable performer in both their card reader and Nikon Z6 (FW 3.00), noting it was significantly cheaper than competitors.
However, this positive sentiment is heavily counterbalanced by a significant number of negative reports centered on a single, critical theme: reliability, especially in Nikon cameras. One user stated bluntly, “My Nikon D850… The card will format and sometimes write… then fail and cause an ‘error’ message.” Another simply said, “I have 2 of these cards, they worked fine in my Nikon Z6, but I have just upgraded to the Z6ii and they don’t work with It.” This recurring issue of random failures and incompatibility, even with up-to-date firmware, is the card’s Achilles’ heel. It suggests a lottery where you might get a perfectly functioning card, or you might get one that is completely untrustworthy for professional work. It’s worth reading these user experiences before making a final decision.
How Does the Integral 256GB CFexpress Card Compare to the Alternatives?
No product exists in a vacuum. To truly understand the value and positioning of the Integral 256GB CFexpress Type B 2.0 Memory Card, it’s crucial to compare it against key competitors in the market. Each alternative serves a different user with different priorities, from legacy support to ultimate performance.
1. SanDisk Extreme Pro 32 GB Compact Flash Memory Card
- Continuous shot-to-shot performance with up to 150 MB/s (1000 X)
- Extreme transfer speed to move data from the card to computer up to 160 MB/s (1067 X)
This SanDisk card represents a different era of digital photography. As a CompactFlash (CF) card, it is not a direct competitor in terms of format or speed. It’s designed for older professional DSLRs that predate the CFexpress standard. Its 160 MB/s speed was once top-of-the-line but is now completely dwarfed by the Integral’s 1800 MB/s potential. Someone might prefer this card only if they are using a camera that specifically requires the CF format, like an older Canon 5D Mark III or Nikon D810. For them, it remains a gold standard of reliability, but for any modern camera user, it’s technologically obsolete for demanding video or burst shooting.
2. SABRENT 1TB CFexpress Type B Rocket CFX Memory Card
- Non-stop shooting, anywhere: Don’t let slow media hold you back. From capturing once-in-a-lifetime events in your town to scenic landscapes in harsh environments across the globe, Sabrent’s...
- Transfers in a blink: Don’t let your memory card slow you down: high read and write speeds mean more time shooting and less time transferring.
The Sabrent Rocket CFX represents the opposite end of the spectrum from the Integral card. This is a premium, high-capacity, and high-performance option for professionals who cannot compromise. With a massive 1TB capacity and blazing speeds (R1700MB/s, W1500MB/s), it’s built for the most demanding cinematic workflows. While its peak speeds are similar to the Integral’s claims, Sabrent has built a strong reputation for reliability and consistent performance. A user would choose the Sabrent over the Integral if their primary concerns are maximum capacity and absolute, unwavering dependability for mission-critical projects. The trade-off is a significantly higher price tag, but for many working professionals, that cost is simply an insurance policy against data loss.
3. Transcend 256GB CFexpress 820 Type B Memory Card
- High-Speed Performance: The CFE820 memory card delivers outstanding read speeds of up to 820 MBs and write speeds of up to 720 MBs, ensuring rapid data transfer and efficient performance
- Durable and Reliable: Built to withstand extreme conditions, the CFE820 memory card is resistant to water, shock, and X-rays, ensuring reliable performance even in harsh environments
The Transcend 256GB card is perhaps the most direct competitor to the Integral. It operates in the same performance tier and capacity, offering a balance of speed and value. Transcend is a more established name in the memory space than Integral, which may give some users more confidence in its long-term reliability and firmware support. Its advertised speeds are slightly lower than the Integral’s, but it’s often the real-world consistency that matters more. A photographer or videographer might choose the Transcend as a “safer” mid-range alternative, potentially sacrificing a bit of theoretical peak performance for the peace of mind that comes with a more proven brand, likely at a slightly higher but still competitive price point.
Final Verdict: A High-Performance Gamble
The Integral 256GB CFexpress Type B 2.0 Memory Card is a product of tantalizing contradictions. On one hand, it offers a specification sheet that rivals the very best in the industry, promising the speeds needed for 8K RAW video and lightning-fast data offloads, all at a price that is hard to ignore. When paired with a compatible camera, like the Canon models it officially supports, our testing shows it can indeed deliver on that promise, making it a potentially phenomenal value.
However, this potential is critically undermined by widespread and consistent reports of incompatibility and random failures, particularly within the Nikon ecosystem. For a professional, reliability is not a luxury; it is the single most important attribute of a memory card. The risk of a card failing mid-shoot, corrupting data, or simply not being recognized is far too great to overlook. Therefore, we can only recommend this card with a major caveat: it may be a superb budget option for users of officially supported Canon and Panasonic cameras who are willing to accept a small degree of risk. For any professional, especially Nikon users, whose livelihood depends on their gear functioning flawlessly every single time, we advise looking at more established and proven alternatives. The potential savings are simply not worth the professional gamble.
