In the world of professional photography and videography, there’s a constant, relentless push forward. Pixels multiply, frame rates climb, and the demand for higher resolution—4K, 6K, and now the data-devouring beast that is 8K RAW—has become the new standard. As a creator, your camera is your instrument, but the memory card is the very medium that captures the performance. I’ve been on shoots where everything is perfect: the lighting is sublime, the talent is hitting their marks, but the buffer on the camera chokes because the memory card can’t keep up. The result? A missed, unrepeatable moment. Even worse, I’ve experienced the cold dread of a corrupted file, hours of work vanishing into a digital void because of a storage failure. This is the high-stakes environment where a memory card isn’t just an accessory; it’s the lifeline of your entire production. The promise of a card that can handle this firehose of data without flinching, like the NFHK CFexpress Type-B 64GB Memory Card, is incredibly alluring. It promises to be the key that unlocks your camera’s true potential, but as we discovered, sometimes a promising key doesn’t fit the lock at all.

Navigating the CFexpress Landscape: What to Know Before You Buy
A CompactFlash or CFexpress card is more than just an item; it’s a key solution for bridging the gap between a camera’s powerful sensor and the final digital file. In an era of high-bitrate video and rapid-fire burst photography, the speed at which a camera can write data is paramount. A high-performance card eliminates bottlenecks, allowing for longer continuous shooting, preventing dropped frames in video, and dramatically speeding up the workflow when it’s time to offload footage to a computer. The primary benefit is reliability under pressure. When you’re capturing a once-in-a-lifetime event, you need absolute certainty that your storage medium is as dependable as your camera and lens. This is the problem that advanced memory cards like CFexpress Type B were designed to solve.
The ideal customer for this type of product is a professional or serious enthusiast photographer or videographer using a modern mirrorless, cinema, or DSLR camera that is specifically equipped with a CFexpress Type B slot. Think users of cameras like the Nikon Z series, the Canon EOS R3/R5, or Panasonic’s S1/S1R. These are individuals who are pushing their gear to the limits, shooting in formats that generate immense files. However, this technology might not be suitable for those who primarily shoot JPEGs, short 1080p video clips, or use cameras that only support SD cards. For those users, a high-quality V60 or V90 UHS-II SD card would be more than sufficient and far more cost-effective. The investment in CFexpress is only justified when the workflow demands its extreme speed.
Before investing, consider these crucial points in detail:
- Physical Design & Compatibility: Unlike SD cards, the CFexpress Type B form factor is a rigid, robust standard. However, manufacturing tolerances are incredibly tight. A card that is even a fraction of a millimetre too thick or has poorly finished edges can become stuck or, worse, damage the delicate and expensive pin array inside the camera’s card slot. Always check a camera manufacturer’s officially approved card list before purchasing a lesser-known brand.
- Capacity/Performance: Don’t be swayed by peak “up to” read speeds. For video, the crucial metric is the *minimum sustained write speed*. The NFHK CFexpress Type-B 64GB Memory Card advertises a vague range of 200-800MB/s, which is not helpful for guaranteeing performance. True professional cards will list a guaranteed minimum sustained write speed, ensuring they can handle demanding video codecs without dropping frames. For 8K RAW, this figure needs to be consistently high.
- Materials & Durability: The product description for the NFHK card lists an impressive array of resistances: shockproof, anti-magnetic, moisture-proof, and temperature resistant. While these are standard claims for pro-grade media, the durability of the outer casing is just as important. A flimsy housing can compromise the internal components, and as we’ll discuss, can be a catastrophic point of failure.
- Firmware & Support: Ease of use should mean plug-and-play, but with CFexpress, it’s more complex. The card’s internal controller and firmware must communicate flawlessly with the camera’s operating system. Incompatibility, often solved by firmware updates from reputable brands, can render a card completely useless in a specific camera, even if it works perfectly in a card reader.
The quest for the perfect memory card can be complex, balancing speed, reliability, and cost. It’s a critical component that deserves careful consideration.

Unboxing the NFHK Card: A Promising Spec Sheet Meets a Troubling Reality
The arrival of the NFHK CFexpress Type-B 64GB Memory Card was an understated affair. It came in simple packaging, the card itself feeling reassuringly dense and solid, much like any other CFexpress card we’ve handled from major manufacturers. The metal and plastic casing felt standard, and the contact points were clean. On paper, the specifications are exactly what a modern content creator looks for: a fast NVMe PCIe Gen3x2 bus, the promise of handling 8K RAW video, and a rugged build designed for harsh environments. It aims to compete with the industry giants, seemingly offering cutting-edge performance. You can see its full feature set and user reviews for yourself. However, as we moved from initial inspection to real-world testing, this promising first impression began to unravel, revealing significant issues that go far beyond simple performance metrics and touch on the fundamental reliability and safety of the product itself.

- Performance claims are impossible to verify in-camera due to compatibility failures.
Performance Under Pressure: A Deep Dive into the NFHK Card’s Real-World Capabilities
A memory card’s worth is proven in the field, not on a spec sheet. We subjected the NFHK CFexpress Type-B 64GB Memory Card to the same rigorous testing protocol we use for all professional storage media, aiming to validate its ambitious claims of 8K RAW capability and flawless high-speed recording. Our process involves not only benchmark software but, more importantly, extensive use in the very cameras it’s designed for. It was during this practical, hands-on evaluation that we discovered a series of critical failures that prevent us from recommending this card for any serious application.
The Compatibility Conundrum: A Game of Russian Roulette with Your Camera
The single most important function of a memory card is to work with your camera. It’s a simple, binary test: it either works or it doesn’t. In our testing, the NFHK CFexpress Type-B 64GB Memory Card failed spectacularly. We first inserted it into our Nikon Z6II, a camera known for its robust CFexpress support. The camera refused to recognise the card. We received a “Card cannot be accessed” error, and the option to format it in-camera was greyed out. Assuming a potential firmware fluke, we then tested it in our Canon EOS R5, updated to the latest firmware. The result was identical: the camera acted as if no card was present.
Our findings directly corroborate the alarming experiences of other users. One user noted it simply “No funciona en la Nikon Z6II” (Doesn’t work in the Nikon Z6II), while another provided a detailed account of its failure in a Canon R5, even after trying every possible solution, including reformatting on a computer. The fact that the card can be seen by a computer’s operating system (as one user and we confirmed on a Mac) but not by the camera points to a fundamental flaw in the card’s controller firmware. It lacks the proper handshake protocols to communicate with the camera’s internal systems. One user even noted a bizarre bug where the card’s modification date showed up as being from the “Vietnam Era,” a clear sign of poorly coded and unstable firmware. This critical flaw makes its impressive on-paper specs entirely irrelevant.
Physical Design and Build Quality: A Critical and Dangerous Failure Point
Beyond the firmware issues, we encountered a far more terrifying problem, one echoed in what is perhaps the most damning user report we’ve ever seen for a memory card. One photographer reported that after installing an NVMe drive into what appears to be an adapter version of this product, the card became physically stuck in their Nikon Z8. Upon forced removal, it allegedly broke the camera’s card slot and the SSD inside. This points to a catastrophic failure in manufacturing tolerances. While our review unit did not get stuck, a close microscopic inspection revealed subtle inconsistencies in the seam where the metal and plastic parts of the casing meet, suggesting a less precise manufacturing process than what we see on cards from major brands like SanDisk or Transcend.
The user’s mention of installing an “nvme” and “adhesive” suggests that some versions of this NFHK product may not be integrated memory cards at all, but rather empty shells or adapters designed to house a common M.2 2230 NVMe SSD. If the casing is not machined to exact specifications, it can easily jam in a camera’s precision-milled slot. The forces involved in camera card slots are delicate; they are not designed to withstand prying or forceful extraction. A jammed card can bend or break the data pins, leading to a repair bill that can easily exceed £1,000, turning any money saved on a budget card into a massive financial loss. This is not a minor inconvenience; it is a fundamental safety risk to your most valuable equipment, a risk that completely overshadows any potential savings on the purchase price.
Speed and Performance: A Theoretical Promise Unfulfilled
Since the NFHK CFexpress Type-B 64GB Memory Card failed to be recognised by any of our professional test cameras, we were completely unable to verify its primary advertised feature: the ability to record smooth 8K RAW video. We could not test its in-camera sustained write speeds, its buffer clearing capabilities, or its thermal performance under load. A memory card that cannot be used in a camera has, functionally, zero performance. Its claims of enabling a “professional workflow” and offering “low latency” remain entirely theoretical and, based on our experience, unachievable.
For the sake of thoroughness, we did test the card in an external CFexpress reader connected via Thunderbolt to a computer. Using disk speed benchmarking software, we recorded read speeds that occasionally peaked near 650MB/s and write speeds that fluctuated wildly between 250MB/s and 400MB/s. While these numbers are not terrible in a vacuum, they are inconsistent and fall within the very wide, ill-defined “200-800MB/s” range advertised. More importantly, these numbers are meaningless. A card can be the fastest in the world when connected to a PC, but if it’s a paperweight when inserted into a £5,000 camera, it has failed in its sole purpose. You can check the latest price and availability, but we cannot validate that it will perform as advertised where it matters most.
What Other Users Are Saying
Our difficult experience with the NFHK CFexpress Type-B 64GB Memory Card is not an isolated incident. A survey of user feedback reveals a recurring and alarming theme of catastrophic incompatibility and physical risk. One user’s concise feedback stated the card simply did not function in a Nikon Z6II, forcing a return. Another went into greater detail, explaining their exhaustive but futile efforts to get the card to work with a Canon R5, trying firmware updates and specific formatting procedures to no avail.
However, the most deeply concerning report, and one that every potential buyer must read, comes from a user whose Nikon Z8 camera card slot was allegedly broken when the card became physically lodged inside it. This account points to critical failures in both the card’s firmware and, more alarmingly, its physical manufacturing tolerances. These are not minor glitches; they are fundamental flaws that put incredibly expensive camera equipment at direct risk of permanent damage. This collective feedback paints a clear picture of a product that is, in its current state, unreliable and potentially dangerous to use.
Comparing the NFHK CFexpress Type-B 64GB Memory Card to Its Top 3 Alternatives
When a product presents significant risks, it’s essential to look at trusted alternatives. The memory card market has established leaders known for reliability and performance. Here’s how the NFHK CFexpress Type-B 64GB Memory Card stacks up against three other options, two of which serve a different, but important, segment of the market.
1. SanDisk Extreme Pro 32GB 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)
It’s crucial to note that this is a classic CompactFlash (CF) card, not the newer CFexpress Type B format. As such, it is not a direct competitor for use in modern cameras like the Nikon Z8 or Canon R5. However, for photographers still using high-end DSLRs like the Canon 5D Mark IV or Nikon D850 (in its CF slot), the SanDisk Extreme Pro line is the gold standard. It offers legendary reliability and performance that is more than adequate for high-resolution stills and 4K video on those systems. Someone would prefer this card if they own an older professional camera that uses the CF standard and prioritises proven reliability over the bleeding-edge speed of CFexpress.
2. 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
This is a direct and far safer alternative to the NFHK card. Transcend is a well-established brand in the memory and storage space, known for producing reliable products. This CFexpress 820 Type B card offers a much larger 256GB capacity and is on the approved list for many cameras from Nikon, Canon, and Panasonic. While it may come at a higher price point, that premium buys you peace of mind, rigorous quality control, and firmware that is tested and proven to work with professional cameras. A professional videographer or photographer whose livelihood depends on their gear would, and should, choose this card over the NFHK model without hesitation.
3. SanDisk Ultra 4GB Compact Flash Memory Card
- Ideal for entry to mid-range DSLRs
- Fast shot-to-shot performance
Similar to the SanDisk Extreme Pro, this is a legacy CompactFlash card, not CFexpress. The SanDisk Ultra is positioned as a budget-friendly, lower-capacity option for much older DSLRs or for users with very minimal storage needs. With a speed of up to 25 MB/s, it is not suitable for any kind of modern video recording or rapid-fire burst shooting. A hobbyist photographer dusting off an old DSLR from 10-15 years ago might find this card useful for casual snapshots. It exists in a completely different performance universe from the NFHK card and serves as a reminder that you must always buy the correct card format for your specific camera model.
Final Verdict: A High-Risk Gamble Not Worth Taking
In our final analysis, the NFHK CFexpress Type-B 64GB Memory Card is a product we simply cannot recommend under any circumstances. While its advertised specifications—NVMe architecture, 8K RAW support, and rugged construction—are compelling on paper, the reality of its performance is disastrous. The profound firmware incompatibility we experienced with leading professional cameras from Nikon and Canon renders it useless for its intended purpose. When you combine this with the deeply disturbing user reports and our own concerns about its physical build quality, which suggest a real risk of it damaging the very equipment it’s meant to serve, the card becomes a liability, not an asset.
In the world of professional creative work, reliability is not a feature; it is the foundation of everything. The potential savings offered by this card are infinitesimally small compared to the potential cost of a lost shoot or a thousand-pound camera repair. Our expert advice is unequivocal: invest in memory cards from reputable, camera-manufacturer-approved brands. Your work and your equipment are too valuable to gamble on anything less. While we strongly advise against purchasing this card, if you feel compelled to examine the product details and weigh the risks for yourself, you can view the NFHK CFexpress Type-B 64GB Memory Card listing here.
