ADATA Premier Extreme 256GB SDXC UHS-I Class 10

Revolutionary Performance
With PCIe Gen3x1 and NVMe support, this memory card delivers read and write performance of up to 800/700 MB/s, making it almost 1.5 times faster than SATA SSDs. Compared to UHS-II SD cards and UHS-I SD cards, it is 2.7 and 8 times faster, respectively.

Like an SSD, but smaller
The Premier Extreme SDXC Express memory card is backward compatible with the UHS-I standard. It can be inserted into digital cameras to capture high-quality photos or 4K videos and then used in a PC with SD 7.0 support for seamless editing or playback. It delivers the same performance as an external SSD but is significantly smaller.

Rated for V30
The Premier Extreme SDXC Express card supports UHS-I video devices with read and write speeds of 100 MB/s and complies with the V30 video speed class. This makes it ideal for use in typical Ultra HD 4K video recording applications to easily create high-quality, professional content.

Plenty of Storage Capacity
With capacities from 256 to 512 GB, the Premier Extreme SDXC Express card offers ample storage space for all your content, so you are no longer limited when creating.

Safe, Durable, Reliable
Your data is safe with the Premier Extreme SDXC Express card. It features an error correction code to ensure data accuracy. In addition, it is waterproof, shockproof, resistant to X-rays and static electricity, and tested for optimal operation in high and low temperatures.

Quick Tips: What is SD Express?
As the quality of audio and video content steadily increases, SSDs have become significantly more important for creators due to their high-speed access to content and applications on their PCs. Originally, SD cards were limited in this regard. With support for PCIe and NVMe, SD Express cards have overcome these limitations. With PCIe Gen3 x1 (SD 7.0), the theoretical transfer speed of an SD Express card is 985 MB/s. In the future, with PCIe Gen4 x1 (SD 7.0/SD 8.0), a theoretical speed of 1970 MB/s will be possible, and with PCIe Gen4 x2 (SD 8.0), a theoretical speed of 3940 MB/s will be possible.

Quick Tips: How SD Express Works
SD Express cards utilize the latest SD 7.0 specification and introduce PCIe and NVMe support to significantly improve read and write speeds. Nevertheless, the form factor remains identical to traditional SD cards. SD Express cards also support UHS-I and are backward compatible with existing UHS-I SD-enabled devices. Thanks to performance optimization, SD Express cards are now comparable to external SSDs in terms of performance, while also offering the advantage of compatibility with SD 7.0-enabled devices.
