The SD card comparison above serves as a guide to help you choose the right product.

At a glance
  • • SD cards come in different formats: SD, SDHC and SDXC. While SD cards typically offer up to 2GB of storage, SDHC cards range from 2GB to 32GB and SDXC cards range from 32GB to several TB. This distinction is important because not all devices are compatible with every card format.
  • The speed of an SD card is determined by its writing and reading speed. There are different speed classes, such as Class 10, UHS-I and UHS-II, which affect how quickly data can be transferred. For demanding tasks like 4K videography or fast burst shooting on cameras, you should choose a card with a higher speed rating.
  • When buying an SD card, you should not only consider capacity and speed, but also reliability and durability. Some cards offer additional features such as waterproofing, shockproofing, and temperature resistance, making them ideal for use in extreme conditions. It's worth investing in a high-quality card to avoid data loss.

An overview of SD cards

SD cards, the small but powerful storage miracles, have become an integral part of the digital world. Whether in Cameras, smartphones or as portable data storage – they play a central role in the storage and transmission of information. In this context, we take a look at the most frequently asked questions about SD cards to help you find the right card for your needs, based on comprehensive SD card tests and comparisons.

What are the differences between SDHC and SDXC cards?

SDHC (Secure Digital High Capacity) and SDXC (Secure Digital eXtended Capacity) are extensions of the original SD format. SDHC cards store up to 32GB, while SDXC cards offer a capacity of up to 2TB. SDXC cards use the exFAT file system, which provides larger file sizes and better performance when processing large amounts of data, such as 4K videos. It is important to note that not all devices support SDXC cards, so you should check your device's compatibility before purchasing.

How important is the speed rating of an SD card?

An SD card's speed class, often indicated by terms such as Class 10, UHS-I and UHS-II, is critical to its performance. These classes indicate the minimum write speed of the card, which is particularly important for tasks such as recording HD video or fast burst shooting in photography. For general use, a Class 10 card is sufficient, while for more intensive applications such as 4K video recording, a UHS-I or UHS-II card is recommended.

What factors should you pay attention to? SD cards Pay attention to the test?

When testing an SD card, you should pay attention to capacity, speed, reliability and compatibility with your device. Check whether the card is fast enough for your needs and whether it has enough storage space for your needs. Reliability is crucial to avoid data loss. Finally, compatibility is important because not all SD cards work in all devices, especially when it comes to SDHC and SDXC formats.

What does UHS mean for SD cards?

UHS stands for “Ultra High Speed” and refers to the interface speed of the SD card. There are two types of UHS: UHS-I and UHS-II. UHS-I offers a maximum transfer speed of up to 104 MB/s, while UHS-II can reach speeds of up to 312 MB/s. For tasks that require fast data transfers, such as shooting high-resolution video, a UHS-II card is ideal, while UHS-I is more than sufficient for everyday tasks.

How to choose the right SD card for your needs?

When choosing an SD card, you should consider your specific needs. For general storage purposes, a standard SDHC card is often sufficient. However, for professional photography or video recording, you should invest in a high-performance SDXC card with a higher speed rating. Check compatibility with your device and consider how much storage space you actually need. An SD card comparison can be helpful in finding the right balance between performance and price.
