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.
 
 
 


 
Generous Storage Capacity

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.
 
 
 


 
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.
 
 
 


 
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.
