CFexpress Type A: High-Speed Storage for Professional Use

Share

In the world of photography and videography, technological advancements are constantly pushing boundaries, and CFexpress memory cards represent one such leap forward. Designed for professional-grade cameras, CFexpress Type A memory cards offer unparalleled speed and reliability, transforming how high-resolution photos and videos are captured and transferred. But with a range of options available, choosing the right memory card can be confusing.

This exploration aims to simplify that decision. You’ll learn the fundamentals of CFexpress Type A, weigh its pros and cons, and understand where it fits in the memory card landscape. Plus, you’ll get a clear picture of who benefits from using them.

What Defines CFexpress Type A?

CFexpress Type A is a memory card standard for professional photographers, videographers, and digital content creators. It uses the super-fast PCIe 3.0 interface and NVMe protocol, enabling fast read and write speeds that surpass traditional SD cards. This is beneficial for demanding tasks like shooting high-resolution images in burst mode or recording high-bitrate 4K and even 8K video.

Delving into the Technical Specs:

• Form Factor: Measuring just 20mm x 28mm x 2.8mm, these cards are smaller than their Type B counterparts.
• Data Transfer Rates: Read speeds up to 800MB/s and write speeds reaching 700MB/s. Lexar’s Professional CFexpress Type A GOLD cards boast read speeds up to 900MB/s and write speeds up to 800MB/s 
• Durability: Constructed using robust materials, making them resistant to extreme temperatures, shocks, and vibrations.

CFexpress Type A Cards vs. Other Memory Card Types

Understanding how CFexpress Type A cards stack up against other memory card types helps to clarify if this storage solution aligns with your needs. Here’s a closer look:

SD Cards: A Staple in the Industry

SD (Secure Digital) cards are the most prevalent type of memory card. This format’s widespread compatibility and affordability make it attractive for photographers and videographers. While standard SD cards may not offer the same speed as their CFexpress counterparts, there’s a wide range of SD card classes to choose from, with the latest UHS-II offering enhanced speeds.

For instance, UHS-II cards promise write speeds of up to 300MB/s. This speed is adequate for photographers shooting RAW images and even some 4K video recording.

CFexpress Type B Cards: Pushing the Limits Further

CFexpress Type B cards are designed for high-performance cameras, especially cinema-grade filmmaking. Traditionally, they offer read speeds up to 1700MB/s and write speeds exceeding 1400MB/s. 

While traditional CFexpress Type B cards offer impressive speeds, Lexar’s SILVER, GOLD, and DIAMOND series push the boundaries even further with their superior performance.

Lexar Professional CFexpress Type B SILVER Series:

• Performance: Up to 1750MB/s read speeds and 1300MB/s write speeds.
• Sustained Write Speed: 1200MB/s.

Lexar Professional CFexpress Type B GOLD Series:

• Performance: Up to 1900MB/s read speeds and 1500MB/s write speeds (1TB and 2TB models).
• Sustained Write Speed: 1300MB/s (1TB and 2TB models).

Lexar Professional CFexpress Type B DIAMOND Series:

• Performance: Up to 1900MB/s read speeds and 1700MB/s write speeds.
• Sustained Write Speed: 1600MB/s.

Although Type B CFexpress cards lead in speed, it comes at a larger physical size. CFexpress Type B cards are valuable for workflows centered around RAW video formats, such as Blackmagic RAW, which need substantial data bandwidth. 

So where does this leave CFexpress Type A cards? They occupy a space between SD cards and CFexpress Type B, representing a balance of performance and portability.

3 Applications and Use Cases for CFexpress Type A Memory Cards

Photography

For professional photographers, capturing the perfect shot often hinges on having the right equipment, and CFexpress Type A cards are an essential part of that toolkit.

These cards offer ultra-fast read speeds of up to 900MB/s and write speeds up to 800MB/s, making them ideal for high-speed shooting scenarios such as sports, wildlife, and action photography. The incredible speed ensures that your camera can keep up with rapid-fire bursts, allowing you to capture every frame with precision.

Moreover, the high-resolution images produced by mirrorless cameras demand substantial storage capabilities, and CFexpress Type A cards deliver just that, with capacities ranging from 80GB to 320GB. Photographers can shoot in RAW format without worrying about running out of space or experiencing delays, enabling them to focus on creating stunning visual art.

Videography

Videographers understand the importance of smooth, uninterrupted recording, and CFexpress Type A cards are designed to meet these exacting standards. With support for 4K and even 8K video recording, these cards provide the necessary bandwidth to handle the massive data rates required for high-definition video.

The fast write speeds ensure that there are no dropped frames or buffering issues, resulting in seamless video capture. This makes CFexpress Type A cards perfect for a range of videography applications, from documentary filmmaking and commercial shoots to live event recording.

Content Creation

In the realm of content creation, versatility and reliability are key. CFexpress Type A cards support a wide array of creative endeavors, from multimedia production to digital art. These cards enable content creators to work with large files and high-resolution media without the frustration of slow transfer rates or insufficient storage.

Deciding if CFexpress Type A Is Right for You

With so many advantages, it’s understandable why creatives are eager to integrate CFexpress Type A into their workflow. But there’s more to consider than impressive specs alone. It boils down to whether these features align with your workflow.

3 Reasons Investing in CFexpress Type A might be worthwhile:

1. The Pursuit of Speed: If slow memory cards hinder your workflow or disrupt your ability to capture moments, switching to CFexpress Type A could make a difference. Think about it as investing in performance upgrades.
2. High-Resolution Workflow Champion: Your work revolves around high-resolution cameras that generate massive files. Speed and efficiency are paramount in your post-processing.
3. Sony Shooters Seeking Portability: If your camera, like certain Sony Alpha and FX series models, exclusively uses CFexpress Type A, investing in them becomes a no-brainer. Their compactness offers a convenience factor when swapping cards or carrying minimal gear.

While most camera equipment will only be compatible with either an SD card or CFexpress Type A card, some Sony cameras work differently; the a7S III has two card slots and each can take a CFe (Type A) card or an SDXC card. 

Alternatively, you might consider sticking to SD cards for the following reasons:

• Staying Within a Budget: When on a tight budget, prioritizing features within a limited price range makes sense, and SD cards offer a broader range of affordable choices. Balancing price and performance helps maximize your investment, especially if peak speeds are not your primary concern.
• Camera Compatibility Takes Center Stage: You value broader camera compatibility and own several camera bodies or brands that predominantly use SD cards.
