Samsung Blazes New Trails with Record-Breaking SD Express microSD Cards

Samsung Blazes New Trails with Record-Breaking SD Express microSD Cards

Tech news

Mar 11, 2024
Get ready to say goodbye to sluggish transfers and hello to lightning-fast performance. Samsung recently unveiled a groundbreaking line of SD Express microSD cards, ushering in a new era of high-speed storage for mobile devices. This blog post dives deep into these innovative cards, exploring their features, potential applications, and the impact they’ll have on mobile technology.

SD Express: Redefining Mobile Storage

Traditional microSD cards, despite their widespread use, have limitations in data transfer speeds. The bottleneck lies in the UHS-I and UHS-II interfaces they typically employ. These interfaces rely on the same technology as older SD cards, limiting transfer speeds to a maximum of around 300 MB/s. This can be a hindrance for professionals and enthusiasts who work with large media files, such as high-resolution photos and 4K/8K videos. The SD Express standard aims to address this by leveraging the PCI Express (PCIe) interface.  PCIe is a high-speed interconnect commonly used in computers for connecting various components. By incorporating PCIe technology, SD Express cards can achieve significantly faster data transfer rates compared to their UHS counterparts. The SD Association, the governing body for SD card standards, outlines two categories of SD Express cards:

SD Express

These cards utilize the full potential of the PCIe interface, boasting maximum theoretical speeds of up to 9.8 Gbps (gigabits per second). This translates to real-world read speeds exceeding 800 MB/s, a monumental leap compared to traditional microSD cards.

SD Express with UHS-I compatibility

These cards offer backward compatibility with UHS-I devices while also supporting the faster PCIe interface. This provides flexibility for users who might have a mix of older and newer devices.

Samsung’s SD Express Powerhouse

Samsung’s new SD Express microSD cards come in two exciting variants:

256GB High-Performance Card

This card boasts a record-breaking maximum read speed of up to 800 MB/s, making it ideal for professional photographers and videographers who capture high-resolution images and 8K videos. The blazing-fast speeds ensure seamless capture, editing, and transfer of large media files. Imagine a photographer capturing a fast-paced sporting event; with an SD Express card, they can offload hundreds of high-resolution photos to their editing software in a fraction of the time compared to a traditional microSD card. This allows them to review and edit photos more quickly, potentially meeting tighter deadlines.

1TB UHS-I Card

This caters to mobile users who generate or store a large volume of data, such as drone operators who capture high-resolution aerial footage, gamers with extensive libraries of mobile games, or professionals who rely on mobile productivity applications that handle large files. For instance, a drone pilot capturing high-resolution panoramic images can store a significant amount of footage on a single card, eliminating the need to swap cards frequently during a shoot.

Beyond Speed: Additional Features

While speed takes center stage, Samsung’s SD Express microSD cards boast additional features that enhance their overall performance and reliability:

Low-Power Design

Optimized firmware and hardware ensure efficient power utilization, minimizing battery drain on your mobile devices. This is crucial for users who rely heavily on their mobile devices throughout the day and don’t want storage limitations to impact battery life.

Thermal Management

Samsung has implemented advanced thermal management solutions to prevent overheating during sustained read/write operations. This is crucial for maintaining peak performance and data integrity. Overheating can not only throttle performance but also potentially damage the card and stored data. Samsung’s thermal management solutions ensure the cards operate within optimal temperature ranges, even during demanding tasks.


These cards are built to withstand harsh conditions. They are water-resistant, temperature-proof, X-ray-safe, and magnet-proof, ensuring your valuable data remains protected. Whether you’re a photographer braving the elements to capture stunning landscapes or a content creator working in dusty environments, these cards can endure the rigors of everyday use.

The Future of Mobile Storage

Samsung’s SD Express microSD cards open doors for exciting possibilities in the mobile realm:

Enhanced Mobile Photography and Videography

Professional photographers and videographers can capture high-resolution images and 8K videos without experiencing transfer bottlenecks. This allows for faster offloading of media files to editing software, streamlining the creative workflow. Imagine a videographer shooting a high-profile event; with an SD Express card, they can quickly transfer hours of 8K footage to their editing suite for faster post-production processing.

Smooth 4K/8K Streaming

With their high speeds, these cards can handle smooth 4K or even 8K streaming on mobile devices, paving the way for a more immersive mobile entertainment experience. Imagine gamers enjoying uninterrupted high-resolution gameplay on their smartphones or tablets, or users streaming their favorite movies and shows in stunning detail without buffering interruptions.

Advanced On-Device AI Applications

The increased storage capacity and data transfer rates are well-suited for on-device AI applications that require large datasets and fast processing speeds. This could revolutionize mobile gaming with more realistic graphics and complex AI-powered opponents. Augmented reality (AR) experiences can become more immersive and interactive, with faster loading times and smoother object recognition. Mobile productivity applications could leverage on-device AI for features like real-time language translation or image recognition-based document organization.

A Look at the Broader Ecosystem

The impact of SD Express technology extends beyond the cards themselves. To fully benefit from the high speeds, compatible devices are needed. We can expect to see a new wave of smartphones, tablets, cameras, and drones equipped with SD Express card readers. As adoption increases, the development of software and applications optimized for the faster transfer rates will likely accelerate. This will create a more robust ecosystem that unlocks the full potential of SD Express technology.

Potential Challenges and Considerations

While SD Express offers significant advantages, there are some challenges to consider:


As with any new technology, SD Express cards are likely to be more expensive than traditional microSD cards at launch. However, the price is expected to decrease as production scales up and adoption widens.

Backward Compatibility

Traditional microSD card readers won’t be able to take advantage of the high speeds offered by SD Express cards. Users will need to ensure their devices have SD Express-compatible readers to benefit from the performance boost.

Form Factor

The physical size of SD Express cards is identical to that of microSD cards. However, there are slight variations in the pin configuration. This shouldn’t be an issue for users with new SD Express-compatible devices, but it’s important to note that SD Express cards might not fit into older microSD card slots designed for the UHS-I standard. Samsung’s introduction of SD Express microSD cards marks a significant leap forward in mobile storage technology. These cards offer record-breaking speeds, massive capacities, and enhanced durability, making them ideal for professionals and enthusiasts who demand the best from their mobile devices. As the SD Express ecosystem matures and adoption increases, we can expect to see a wider range of applications that leverage the high-performance capabilities of these cards, transforming the way we capture, store, and interact with data on the go. The future of mobile storage is undoubtedly bright, and SD Express technology is poised to play a major role in shaping it.
