Earlier generations of high-performance memory cards were built around interfaces that once felt nearly limitless. Since then, sensors grew larger, codecs became more data-hungry, and frame rates that once seemed exotic are now the standard on mainstream professional bodies.
Storage technology that once had headroom to spare started to feel like it had a ceiling Lexar® Professional SILVER CFexpress 4.0 Type B Card answers that by building on the PCIe interface and NVMe protocol that made earlier CFe card generations fast, while unlocking substantially higher bandwidth. The Lexar Professional SILVER CFexpress 4.0 Type B Card takes advantage of these advances to deliver higher performance.
Performance That Matches Modern Production
Thanks to read speeds up to 3600MB/s, write speeds up to 3000MB/s, and a sustained write speed of up to 2600MB/s1, the Lexar Professional SILVER CFexpress™ 4.0 Type B Card offers performance numbers that make cinematographers and sports photographers take notice.
Built on the PCIe 4.0 interface with NVMe protocol support, the Lexar Professional SILVER CFexpress™ 4.0 Type B Card is engineered to sustain the kind of continuous, high-bitrate data flow that modern professional cameras demand. That architecture is what makes seamless 8K RAW video capture possible without frame drops. With this card, creators shooting high-resolution cinema footage, high-speed burst photography, or dense RAW image sequences have headroom to work the way they want to, not the way their storage forces them to.
For photographers shooting fast-moving action like wildlife, motorsports, or sports, the write performance translates directly into more confidence at the moment of capture. Buffer clearing happens faster, burst sequences run longer, and the card gets out of the way so the photographer can stay focused on the moment rather than watching a busy light blink on the back of the camera.
Built for Different Disciplines
The speed of the Lexar Professional SILVER CFexpress™ 4.0 Type B Card translates differently across disciplines, and fortunately, its performance holds up in each one.
For cinematographers and documentary shooters, sustained write performance enables long, uninterrupted takes in 8K RAW or high-bitrate codecs, without the card becoming the limiting factor in a scene that can’t be reset.
For sports and wildlife photographers, the emphasis shifts to burst depth and buffer recovery: A card that clears quickly means more usable frames from a play at the goal line or a bird taking flight, moments that don’t wait for hardware to catch up. For studio and commercial photographers, the benefit shows up in transfer efficiency, as large RAW files move on and off the card faster, speeding up the path from capture to client delivery.
Engineered for the Realities of Professional Work
Creative professionals don’t shoot in controlled environments. They shoot in the rain, in the desert, and on mountainsides. A memory card that performs brilliantly in a lab but fails in the field is worthless to the people actually relying on it. That’s why durability is baked into the Lexar Professional SILVER CFexpress™ 4.0 Type B Card design from the ground up.
The Lexar Professional SILVER CFexpress™ 4.0 Type B Card is rated to operate reliably across a wide temperature range, from -12°C to +72°C, and can withstand storage conditions from -25°C to +85°C, meaning it can handle everything from a frozen mountaintop shoot to a scorching desert production without missing a beat. It’s also vibration-resistant, dust-resistant to an IP5X rating, and built to survive drops from up to five meters.
Professionals who are constantly swapping cards between cameras, readers, and backup stations over the life of a production need a reliable storage solution that lasts. The Lexar Professional SILVER CFexpress™ 4.0 Type B Card offers roughly seven times the compression resistance of standard SD cards, along with bend-resistance and up to 12,000 insertion-and-removal cycles.
A card that can’t take a hit, resist moisture, or handle temperature extremes is a liability waiting to happen on set.
A Workflow, Not Just a Card
When paired with the Lexar Professional Workflow CFexpress 4.0 Type B Card Reader, the Lexar Professional SILVER CFexpress™ 4.0 Type B Card is designed to accelerate the offload process.
For video teams working against tight turnaround times, or photojournalists filing from the field, that efficiency is often the difference between making or missing a deadline.
Every Lexar Professional SILVER CFexpress™ 4.0 Type B Card also comes with a limited lifetime warranty2, underscoring the confidence Lexar has in the product’s construction and longevity to give professionals one less thing to worry about as they build out their storage arsenal.
Rigorously Tested at Lexar Quality Labs
Every Lexar product passes through the Lexar Quality Labs before it ever reaches a customer. The Lexar testing facilities test for compatibility and performance across thousands of different cameras and devices.
The Lexar Quality Labs reflects decades of accumulated experience working directly with camera manufacturers and building products that behave predictably across an enormous range of hardware, rather than cards that are fast in a synthetic benchmark but unreliable once paired with a specific body in the field.
Available Where Creators Need It
A single day of event photography might comfortably fit on the 512GB card, while feature productions or multi-day documentary shoots will likely lean toward the 1TB option to minimize card changes during critical moments. The Lexar Professional SILVER CFexpress™ 4.0 Type B Card is available in both 512GB and 1TB capacities, giving creators flexibility depending on the scale and length of their productions.
The Bigger Picture
As camera technology continues its march toward higher resolutions, higher frame rates, and richer color depth, the burden on storage media only grows heavier.
Manufacturers who can’t keep pace risk becoming the bottleneck in an otherwise cutting-edge production pipeline. With the Professional SILVER CFexpress 4.0 Type B Card combined with a Professional Workflow CFexpress 4.0 Type B Card Reader, Lexar demonstrates a relentless focus on real-world performance, uncompromising durability, and a workflow ecosystem designed around how creative professionals actually work.
