Switch 2 Ready! Unleash Ultimate Game Experience
The next generation Premier Extreme SD7.1 Express memory card uses Silicon Motion SM2708 SD Express Controller, which has passed compatibility test of Nintendo Switch 2. This optimizes the entire gaming journey; allows players to fully unleash their console's capabilities without being constrained by storage bottlenecks.
Flexing microSD Express
The memory card that knows you best! The next generation Premier Extreme SD7.1 Express memory card delivers transfer performance of up to 800MB per second, which is 1.5 times faster than a SATA SSD, 2.7 times faster than a high-speed UHS-II SD card, and 8 times faster than a standard UHS-I SD card. One card supplies the excellent file transfer efficiency you need!
Lightspeed
The Premier Extreme SD7.1 Express memory card adopts PCIe and NVMe protocols, using the PCIe Gen3 x1 bus speed to increase read/write performance to 800/700MB per second, giving creators silky transfer speeds and reducing waiting time. Whether large files, random small files, dynamic or static image output, all transfers are completed at the highest performance.
Performs Like a Miniature SSD
In addition to smartphones, smaller microSD Express memory cards can also be used in VR headsets, smart home devices, dynamic cameras, and drones. In particular, imaging applications such as 4K and 8K require greater access speed and capacity. The microSD Express memory card is multi-device and backward compatible, keeps up with the rollout of the 5G ecosystem, and facilitates the gorgeous production of creators.
Ultra-clear Dynamic Recording with no Frame Drops
The Premier Extreme SD7.1 Express memory card can maintain a minimum write speed of nearly 150MB/s*, and is backward compatible with video speed classes below V30. It perfectly facilitates low latency, high-speed photography without frame drops, and meets the needs of high-resolution 4K, 8K video recording and streaming audio and video applications.
*The aforementioned minimum write speed of 150MB/s is close to the “E150”specification defined by the association.
Please refer to the SD Association website for information regarding SD Association Express Speed Class specifications
Generous Storage Capacity
Available in 256GB and 512GB capacity options, the Premier Extreme SD7.1 Express memory card can record tens of thousands of photos and hours of 4K videos. There is no need to worry about interrupting your work during long recording sessions due to insufficient memory card storage space.
Safe, Durable, and Reliable
The microSDXC Express memory card is equipped with an SSD-level LDPC (Low-density parity-check code) automatic error correction function and has passed liquid, shock, X-ray, anti-static and extreme temperature resistance tests to deliver effective protection for important data.
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 (SD7.1), the theoretical transfer speed of an SD Express Card is 985MB/s. Future releases will include PCIe Gen3 x2 (SD8.0) with a theoretical speed of 1970MB/s and with PCIe Gen4 x2 (SD8.0) a theoretical speed of 3940MB/s.
QuikTIPS: How does SD Express works
SD Express Cards adopts the latest SD7.1 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 SD7.1 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
