Revolutionary Performance
With support for PCIe Gen3x1 and NVMe, this memory card delivers read and write performance of up to 800/700 MB/s, which is roughly 1.5 times faster than SATA SSDs. When compared to UHS-II SD cards and UHS-I SD cards, it's about 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 take high-quality photos or 4K videos, and then inserted into a PC that supports SD 7.0 for seamless editing or playback. It performs just like an external SSD, but much smaller.
Rated for V30
The Premier Extreme SDXC Express Card supports UHS-I video equipment, with a read and write speed of 100MB/s, and conforms to the V30 Video Speed Class. This means it's fully qualified to work with mainstream Ultra HD 4K video recording applications to help you create high-quality, pro-level content.
Lots of Storage Capacity
With capacities ranging from 256GB to 512GB, the Premier Extreme SDXC Express Card has plenty of space for all your content so you can create without limitations.
Secure, Durable, Reliable
Your data is safe with the Premier Extreme SDXC Express Card. It features error correcting code to ensure data accuracy. What's more, it's waterproof, shock-proof, x-ray-proof, static-resistant, and tested to operate optimally in high and low temperatures.
QuikTips: What is SD Express?
With ever higher quality audio and video content, creators have embraced SSDs with their high-speed access to content and applications on their PCs. SD Cards have traditionally been 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 985MB/s. In the future, with PCIe Gen4 x1 (SD 7.0/SD 8.0) a theoretical speed of 1970MB/s will be possible and with PCIe Gen4 x2 (SD 8.0) a theoretical speed of 3940MB/s will be possible.
QuikTips: How does SD Express works
SD Express Cards adopts the latest SD 7.0 specification and introduces PCIe & NVMe support to greatly improve read and write performance. Despite this, the form factor remains the same as ordinary SD Cards. SD Express Cards also support UHS-I and are backward compatible with existing UHS-I SD enabled devices. With their upgrade in performance, SD Express Cards are now comparable to external SSDs in performance with the added benefit of compatibility with SD 7.0 enabled devices.

- A：
SD Express cards should be used with HOSTs that support SD Express interface. Actual performance depends on both memory card and Host as explained in below graphs.

- A：
The SD Association has defined various Speed Class standards to answer a demand for advanced video quality recording. Speed Class symbols indicated to host and card products help users decide the best combination for reliable recording (no frame drop). Before use, we recommend checking whether the card’s speed class meets your device’s specifications for optimal performance.
- A： There are lots of reasons that cause memory cards to fail to be recognized. Such as: a. Power has been off during data transfer. b. Memory card was removed during data transfer. c. Taking photos when the battery status is low. d. Memory cards go through X-ray machine. e. Memory cards are close to strong magnetic devices. If your memory card is unable to be read yet meet none of the above situations, please contact us via https://www.adata.com/en/contact or visit our customer service site for further help.
- A： Memory cards cover a wide range of devices when it comes to data storage, including dash cam, action cameras, laptop/PCs, game consoles, smartphones, etc.
- A： The differences in the display of capacity are due to differences in calculation between the computer operating system and the storage device's Controller IC. The storage device usually calculates in the decimal system, while the computer operating system calculates on the basis of the binary system. The calculation of the storage device: 1TB=1000GB, 1GB=1000MB, 1MB=1000KB, 1KB=1000Bytes. The calculation of the operating system: 1TB=1024GB, 1GB=1024MB, 1MB=1024KB, 1KB=1024Bytes. For example, a storage device marked with having 128GB capacity, 128GB=128*1,000*1,000*1,000=128,000,000,000Byte. But, the computing unit of the computer calculation is a binary system, so the 128GB calculated by the storage device is converted into bytes, 128,000,000,000Bytes, so what will be displayed through computer’s calculation method is 128,000,000,000/1024/1024/1024≒119GB. The fastest way to calculate: The capacity labeled on the product x 0.93is about equal to the actual capacity recognized in the computer. Please note that actual capacity may vary depending on OS or host device.
- A： This could happen because 1) Write protection switch is locked. 2) Too many bad data block resulting in memory cards locked by firmware. If your memory card is unable to delete files or format and meet none of the above situations, please contact us via https://www.adata.com/en/contact or visit our customer service site for further help.
- A： Currently the general public uses Smartphones and Tablets with many small software applications and game-based programs. Higher IOPS means the device can more quickly read and write the many small files used by these programs, resulting in more speed and better natural support.
- A： We suggest ADATA’s Premier or Premier Pro series microSDHC or SDHC cards. For more information, please visit toHere
