Reaching new heights of speed: Lexar launches ultra-fast CFexpress memory cards
In the digital imaging era, the read and write speed of memory cards has always been a bottleneck that restricts creators from exercising their creativity. This situation is changing dramatically. The latest CFexpress 4.0 memory card from Lexar will undoubtedly bring a new experience to image creation.
Superior speed Write and read double breakthroughs
For professional image creators, the read and write speed of the memory card directly determines the work efficiency. In the past, even top-of-the-line memory cards often had read and write speeds of around 1GB/s. But the advent of the CFexpress 4.0 standard has completely changed this pattern.
Lexar's new Diamond Series (Type BCFexpress 4.0 memory cards can achieve maximum read speeds of 3600MB/s and write speeds of up to 3300MB/s. This is already the fastest memory card on the market, with read and write speeds more than double that of the previous generation CFexpress card. The Gold series (Type A) also performs well, with a maximum read of 1800MB/s and a write of 1650MB/s, making it the fastest Type A memory card.
This astonishing speed breakthrough is inseparable from the core technology of CFexpress 4.0 using the PCIe Gen 4 interface. The PCIe Gen 4 interface brings double the bandwidth of the previous generation, radically improving the read and write capabilities of memory cards. The CFexpress 4.0 standard points to a new direction for the speed of memory cards.
The efficiency of image data transmission has been greatly improved
The improvement of the read/write speed of the memory card directly brings about a significant improvement in the efficiency of image data transmission. This is undoubtedly a major benefit for professional image creators.
In the past, when shooting ultra-high-resolution videos such as 8K, the write speed of the memory card often quickly became a bottleneck, limiting the recording time of the video. But with the CFexpress 4.0 memory card, this problem is no longer there. With a write speed of 3300MB/s, the Diamond series can fully support 8K 120fps stress-free recording.
In the post-production process of the video, the ultra-high read speed of CFexpress 4.0 will also bring great optimization to the workflow. Reading large amounts of video footage from a memory card used to be a time-consuming and labor-intensive task, but now the process is much more efficient and convenient.
Whether on set or in post-production, the CFexpress 4.0 memory card will bring a new and efficient experience to image creators, unleashing the unlimited potential of creators.
Excellent durability and high-capacity design
In addition to its exceptional speed, the new Lexar cards are designed for durability and high capacity to help you create images.
With a rugged metal casing, these cards are designed to operate reliably in harsh environments and withstand a wide range of weather and physical shocks. The Diamond series has a maximum capacity of 2TB and the Gold series has a maximum capacity of 1TB, which is sufficient to store a large amount of high-quality image data.
Lexar's new card is not only "fast", but also "ruthless". This excellent comprehensive performance will surely win the favor of the majority of image creators.
Leading the direction of technology development in the industry
The emergence of the CFexpress 4.0 standard will bring a new direction for the memory card industry. As a leader in this field, the launch of Lexar's new products will undoubtedly lead the industry into a new stage of development.
The ultra-high speed of the CFexpress 4.0 memory card will greatly meet the storage needs of future photography and video equipment. With the popularity of 8K and even 16K resolutions, the demand for storage speed will only increase day by day. With the solid foundation of CFexpress 4.0, it is believed that the development of storage technology will keep pace with the advancement of imaging equipment.
The launch of the CFexpress 4.0 standard will also bring new vitality to the entire memory card ecosystem. Related accessories such as card readers and host interfaces will usher in new development opportunities.
The introduction of Lexar's new products has ushered in a new era of memory cards that will have a profound impact on the entire imaging industry. This is a major development that will surely go down in the history of memory card development.
Notes on memory card selection
When shopping for a memory card, in addition to focusing on read and write speed, there are a few other details that we need to pay attention to to ensure that we choose the most suitable memory card for our workflow.
Write speed is crucial to the experience of shooting videos. When shopping for a memory card, we need to make sure that the write speed is fast enough to support the desired video resolution and bitrate, otherwise frame drops will occur.
We need to understand how the speed class of the memory card is identified. Different associations and manufacturers have different standards, and it's important to be aware of these markings in order to get an accurate grasp of the actual performance level of the card.
We also need to pay attention to the problem of matching the memory card with the camera. Some cameras only support certain types of memory cards, and we need to first confirm which memory cards our camera supports, so as to avoid incompatibilities.
Principle of matching memory card with camera
For professional image creators, choosing the right memory card to match the camera is crucial. Getting this right match maximizes the performance potential of your equipment.
Usually, the type of memory card slot of the camera determines which type of memory card we need to use. For example, Sony's high-end mirrorless cameras only support CFexpress Type A and SD cards, so we need to equip them with corresponding memory cards.
When choosing a memory card, we also need to consider the camera's need for storage speed. Cameras that shoot high-resolution videos need to be equipped with a memory card that is high enough to ensure smooth video recording.
Choosing the right memory card for the camera requires us to have enough understanding of the specific specifications of the camera, combined with our actual shooting needs, and comprehensively consider multiple factors of the memory card to make the best choice.
