Filming in 4K is becoming increasingly common these days, whether for professional or personal projects. This ultra-high-definition resolution offers remarkable image quality, but it also requires hardware that’s up to the task, especially when it comes to storage. The memory card then becomes a central component of your setup. It must be not only fast, but also reliable and spacious enough to handle the high bitrates generated by 4K videos.
Not all memory cards are created equal, and some can cause slowdowns or even recording errors if they’re not designed for 4K recording. So, how do you choose the right one from the many options available on the market? We’ve analyzed three SD memory cards that stand out for their performance and reliability.
1. SanDisk 512GB Extreme PRO SD Card
The SanDisk 512GB Extreme PRO SD card is a benchmark in the world of video memory cards. Designed for professional videographers, it offers read speeds of up to 200MB/s and write speeds of up to 140MB/s. This performance allows you to record 4K UHD streams without the slightest interruption. Its large 512GB capacity provides a very comfortable working space for long filming sessions without having to change cards, which is ideal for outdoor shoots or extended interviews. In addition, it is designed to withstand extreme conditions: shock, water, high temperatures.
2. Lexar SILVER PRO SD Card
The Lexar SILVER PRO SD Card is for demanding content creators who want the ultimate speed for their shoots. With impressive read speeds of up to 280MB/s and write speeds more than enough for 4K, this card is ideal for mirrorless, DSLR, and professional 4K cameras. It’s designed to deliver consistent performance even under heavy use. Its speed increases post-production possibilities, especially when transferring files to a computer for editing.
3. Gigastone 256 GB SDXC Memory Card
The Gigastone 256GB SDXC Memory Card is a great option for amateur or semi-professional videographers looking for a powerful solution without breaking the bank. While it’s more affordable, this card is still perfectly capable of handling 4K video recording. Its 256GB capacity allows for several hours of recording, and its performance is robust enough to ensure a smooth experience. It’s also ideal for those looking to film one-off events, travel, or occasional creative projects.
What to check before buying
Before making your choice, several criteria must be taken into account to avoid unpleasant surprises during filming:
- Speed Class : For 4K, a U3 or V30 class is the absolute minimum. This ensures the sustained write speed needed to avoid interruptions.
- Storage capacity : 4K video takes up a lot of space. Choose cards with a minimum capacity of 128 GB. If you’re filming a lot or over several days, a 256 GB or 512 GB card will be more convenient.
- Compatibility : Make sure your device supports the card type (SD, SDHC, SDXC) and is capable of taking advantage of its performance. A card with too much performance in a limited device won’t provide any benefit.
- Robustness : Some cards are designed to withstand water, shocks, X-rays, and even extreme temperatures. A plus for adventurers.
Conclusion
Choosing a memory card for 4K video shouldn’t be taken lightly. The quality of your images and the reliability of your recordings depend on it. If you’re looking for the best possible performance, the SanDisk 512GB Extreme PRO SD card is a great investment. For a very fast and reliable alternative, the Lexar SILVER PRO SD card fits the bill perfectly. Finally, for those looking for a budget-friendly solution without sacrificing too much performance, the Gigastone 256GB SDXC Memory Card is an option worth serious consideration. In any case, be sure to choose a card certified for 4K video to ensure a smooth, stable recording experience without unpleasant surprises.
