Main Facts
Wise Advanced, globally recognized in the imaging industry simply as Wise, has officially announced its next-generation lineup of CFexpress 4.0 Type B memory cards. Designated as the MK-IV series, these high-performance storage media introduce an industry-first dual Video Performance Guarantee (VPG) certification standard. Engineered specifically to bridge the technological gap between legacy cinema hardware and tomorrow’s uncompressed 8K and 12K capture devices, the MK-IV series promises to redefine reliability, thermal efficiency, and sustained data throughput for professional cinematographers and hybrid content creators.
Available in four robust capacity tiers—512GB, 1TB, 2TB, and a massive 4TB—the new cards leverage the immense bandwidth potential of the CFexpress 4.0 specification (PCIe Gen 4 architecture). They boast maximum read speeds of up to 3,700 MB/s and maximum write speeds reaching up to 3,400 MB/s. However, the true headline is their unique dual VPG certification, which guarantees uninterrupted, dropped-frame-free sustained writing speeds across a wide array of demanding video codecs.
The breakdown of the new Wise MK-IV series capacities, certifications, and performance specs includes:
- 512GB Model: VPG400 and VPG800 certified; max write speed of 3,000 MB/s; sustained write speed of 900 MB/s.
- 1TB Model: VPG400 and VPG1600 certified; max write speed of 3,200 MB/s; sustained write speed of 1,800 MB/s.
- 2TB Model: VPG400 and VPG1600 certified; max write speed of 3,400 MB/s; sustained write speed of 3,300 MB/s.
- 4TB Model: VPG400 and VPG1600 certified; max write speed of 3,400 MB/s; sustained write speed of 3,300 MB/s.
Beyond raw throughput, Wise has dramatically optimized the processing efficiency of the MK-IV architecture. The cards consume approximately 45% less power and generate about 45% less heat than conventional PCIe Gen 4 media solutions. This radical drop in thermal output virtually eliminates thermal throttling—a notorious bottleneck during long-form, high-bitrate RAW video shoots. Scheduled to hit shelves globally in early October, the MK-IV series aims to become the definitive unified media solution for modern production studios.
Chronology: The Evolution of Cinema-Grade Storage
To understand the magnitude of Wise’s latest release, one must look at the rapid evolutionary timeline of digital cinema workflows and memory card technology.
The Early Days of CFexpress and the Need for Speed
When the CompactFlash Association (CFA) introduced the CFexpress format, it represented a monumental leap past legacy Secure Digital (SD) and CompactFlash (CFast) cards. By migrating from SATA and slower serial buses to the PCIe interface and NVMe protocol, memory card speeds jumped exponentially. Early iterations (CFexpress 1.0 and 2.0) allowed photographers and filmmakers to record high-resolution continuous bursts and compressed 4K video with ease.
However, as cinema camera manufacturers like RED, ARRI, Blackmagic Design, and Sony began pushing boundaries with high-framerate 8K and open-gate 12K RAW recording, the demands on storage media skyrocketed. Filmmakers frequently experienced dropped frames when memory cards could not maintain a guaranteed minimum write speed over extended periods.
The Rise of VPG Standards
To combat unpredictable write drops, the CompactFlash Association established Video Performance Guarantee (VPG) profiles. Standards like VPG200 and VPG400 guaranteed minimum sustained write speeds of 200 MB/s and 400 MB/s, respectively. These ratings quickly became mandatory requirements for high-end cinema cameras capable of shooting internal, visually lossless codecs.
As sensors evolved, so did bitrates. The release of cameras requiring VPG600, VPG800, and rumors of even higher thresholds forced media manufacturers into a tight corner. Production houses frequently found themselves purchasing fragmented card inventories—some media worked exclusively with older cinema bodies, while newer flagships demanded cutting-edge specifications. This fragmentation complicated on-set workflows, increased overhead costs, and introduced human error when swapping media during fast-paced shoots.
The CFexpress 4.0 Revolution and Wise’s Strategic Pivot
The formal ratification of the CFexpress 4.0 specification doubled the theoretical performance ceiling by utilizing PCIe Gen 4 lanes. While brands rushed to market with high peak-speed cards, many struggled with the severe thermal consequences of pushing data at rates exceeding 3,000 MB/s. High heat generation often led to thermal throttling, forcing cameras to shut down mid-take to protect the hardware.

Recognizing these compounding industry pain points, Wise Advanced spent the development cycle leading up to late 2026 re-architecting its internal processing chips. Rather than simply chasing peak numbers, Wise focused on deep power optimization and dual-tier compatibility, culminating in the development and announcement of the MK-IV series.
Supporting Data & Technical Deep Dive
The architectural achievements of the Wise MK-IV series are backed by robust empirical data. When evaluating storage media for mission-critical film sets, filmmakers look past marketing claims and examine sustained performance, environmental resilience, and thermal dynamics.
Throughput and Sustained Performance Metrics
While peak read (3,700 MB/s) and write (up to 3,400 MB/s) speeds grab attention, sustained write speed is the ultimate metric for professional videographers. If a card’s write speed dips below the bitrate demanded by a camera’s video codec, the recording stops abruptly—a catastrophic failure on a live set.
The Wise MK-IV series addresses this by securing dual VPG certifications, proving that the cards can operate reliably across multiple performance tiers. The entry-level 512GB card achieves a VPG800 rating, guaranteeing a stable minimum write speed of 800 MB/s (though its actual sustained write sits impressively at 900 MB/s). Meanwhile, the 1TB, 2TB, and 4TB variants bypass the VPG800 tier entirely, jumping straight to VPG1600 certification. This guarantees a staggering minimum sustained write speed of 1,600 MB/s, with the 2TB and 4TB versions pushing actual sustained writes up to 3,300 MB/s. This capability makes them more than capable of capturing uncompressed, multi-channel 12K RAW cinema footage.
Thermal Efficiency and Power Management
Perhaps the most notable engineering breakthrough in the MK-IV series is its thermal profile. Traditional high-speed PCIe Gen 4 storage solutions run notoriously hot, often requiring bulky external heatsinks or running the risk of entering thermal protection modes when housed inside enclosed camera card slots.
Wise’s proprietary low-power controller architecture yields remarkable results:
- 45% reduction in power consumption compared to standard PCIe Gen 4 media.
- 45% reduction in heat generation, drastically widening the thermal headroom during marathon shooting sessions.
This efficiency means that even during continuous, high-bitrate 8K RAW recording in tropical or desert environments, the risk of thermal throttling is virtually eliminated.
Physical Durability and Environmental Tolerances
Professional sets are notoriously punishing environments. To survive the rigors of documentary, wildlife, and commercial field production, the Wise MK-IV cards are built to withstand extreme conditions:
- Shockproof construction to protect against accidental drops onto hard studio floors or rocky terrain.
- X-ray proof design, ensuring data integrity when passing through airport security checkpoints during international travel.
- Wide operational temperature range, certified to function reliably in environments spanning from -12°C to 72°C (10°F to 162°F).
Official Responses and Industry Perspectives
The introduction of the MK-IV series has drawn significant attention from industry analysts and professionals alike, particularly regarding how it solves long-standing equipment compatibility headaches.
Insights from Wise Management
Czardas W., Product Manager at Wise Advanced, emphasized that the new series was designed from the ground up to eliminate the friction points that plague modern film crews.

"The Type B MK-IV series is our definitive work for the CFexpress 4.0 generation," stated W. "By securing our dual VPG certification and integrating an advanced low-power chip, we’ve addressed the two most significant hurdles for professionals—hardware compatibility and thermal management. Production time is too critical to worry about memory media."
Wise expanded on this philosophy in official press statements, explaining the deliberate choice behind the dual VPG approach:
"This comprehensive approach provides total reliability across both legacy and next-generation systems, allowing production teams to utilize a single, unified media solution covering all systems."
Industry Reactions to Evolving Camera Standards
The timing of Wise’s announcement aligns closely with a broader industry trend toward stricter memory requirements. Analysts point to recent hardware releases—such as Sony’s FX5, which demands rigorous VPG ratings even within its CFexpress Type A ecosystem—as clear indicators that upcoming cinema camera fleets will push memory requirements even higher.
Cinematographers and digital imaging technicians (DITs) have long voiced frustration over having to buy entirely separate suites of memory cards whenever upgrading camera bodies. By engineering cards that span multiple VPG tiers (such as a single card holding both VPG400 and VPG1600 certifications), Wise has directly targeted this workflow inefficiency.
Implications for the Professional Filmmaking Ecosystem
The release of the Wise MK-IV CFexpress 4.0 Type B series carries several profound implications for the future of digital asset management, hardware production, and on-set efficiency.
1. The Death of Media Fragmentation
For years, rental houses and production companies maintained heavily segregated inventories of memory cards. A card optimized for a 2020 cinema camera might fail instantly inside a 2026 flagship model due to stricter VPG demands. By engineering cards with dual VPG compliance, Wise has established a precedent for backward and forward compatibility. A single 4TB MK-IV card can seamlessly transition from a legacy B-camera shooting compressed 4K log to an A-camera recording bleeding-edge 12K RAW, reducing equipment clutter and lowering total cost of ownership for production studios.
2. Pushing the Boundaries of RAW Video Capture
As camera manufacturers continue to increase sensor resolutions, dynamic range, and frame rates, storage media has frequently been the bottleneck holding back innovation. With sustained write speeds reaching 3,300 MB/s and verified VPG1600 certifications, hardware engineers no longer need to restrict recording bitrates out of fear that the market lacks capable media. Filmmakers can comfortably embrace uncompressed, high-bitrate codecs without worrying about frame loss or data corruption.
3. Setting a New Benchmark for Thermal Engineering
The drastic reduction in heat and power consumption demonstrated by Wise’s new low-power controller sets a new design standard for the industry. As data transfer speeds inevitably climb toward future PCIe Gen 5 and Gen 6 standards, thermal management will remain the ultimate engineering hurdle. Wise’s success in cutting heat output by 45% proves that high performance does not have to come at the cost of thermal instability, paving the way for more compact, fanless camera designs that rely on internal card cooling.
Outlook and Availability
As the industry prepares for the official retail launch in early October, anticipation is high. While official pricing has not yet been publicly disclosed, the market response suggests that studios are eager to adopt a unified, future-proof media standard. If the Wise MK-IV series delivers on its ambitious promises in the field, it will not only cement Wise’s status as an industry leader in digital storage but also permanently raise expectations for what professional memory cards can—and should—achieve.
