JMicron delivers the World's First USB to SD Express Card Reader solution to meet the rapidly-expanding data nowadays from anywhere. SD Association (SDA) has announced a new SD7.x specification, which introduced with SD Express featuring a PCIe NVMe protocol improves the transfer rate up to 985MB/s. The new SD Ultra Capacity (SDUC) cards would support cards up to 128TB.

SD Express leverages PCIe NVMe interface

SD7.1 (SD Express) is a revolutionized removable storage designed for data-hungry world. Since the data is being created and stored everywhere and it’s adding to the growing complexity. SDA has geared the specification up for the data growth and devoting to reduce data loss.

By adding the advanced PCIe 3.0 specification and NVMe 1.3 protocol, SD Express can deliver faster access and transfer rate, which enable to deliver a whopping performance up to 985MB/s. It can benefit from the features of high bandwidth and low latency. Through the intercorporation of PCIe NVMe protocol, SD Express can offer the SSD-like performance, empowering a superior new user experience for multi-processing environments.
 

Also, SD7.1 is backward compatible and interoperable with legacy SD interface (UHS-I). Allowing a card with SD7.1 to operate interchangeably in legacy SD hosts; the SD7.1 card reader can detect the upper row of pin for UHS-I SDR104 in existing card.

To meet the rise of various mobile multimedia devices and new storage media, JMicron solution can fulfill the scalability of storage and high performance requirements. The new SD7.1 standard also increases the maximum capacity and speed significantly. For sake of the demand for higher capacity memory grows continuously, a new specification called SD Ultra Capacity (SDUC) has been introduced. Whereas prior SDXC is limited to 2TB, the SDUC just boost the storage capacity up to an incredible 128TB. 


 

Ultra-Capacity Embraces All Your Memories

SD7.1 can meet with the burgeoning storage needs and upcoming demands of applications, which extremely require for speed and capacity. Moreover, the blazing speeds are especially essential for high-resolution and high-performance content application and user scenario such as: 4K/8K video capture, data-intense wireless communication, speed-hungry applications, mobile computing devices, multi-channel IoT devices and automotive storage needs. It expands some new opportunities for SD cards in mobile devices, action cam, VR/AR, drones, gaming and other applications that press for high performance removable memory cards in this ever-evolving market trend.


 


 



Beyond Your Expectations

In order to perfectly meet the market demands, JMicron has developed a variety of silicon chip for the upcoming SD7.1 specification. Since the expandability of storage media has become an emerging trend.  Our solution combines with multimedia interfaces which enabling all these high capacity storages to transfer content quickly and stably with an ever-faster speeds.    
Including: 

  • JMS581.........................................USB 3.2 Gen2x1 to SATA 6Gbps, PCIe Gen3x2, SD7.1 and Offline File Copy
  • JMS581LT.....................................USB 3.2 Gen2x1 to SATA 6Gbps, PCIe Gen3x2, SD7.1
  • JMS581SD....................................USB 3.2 Gen2x1 to SD7.1

Through the integration of PCIe and NVMe into SD, it brings an innovative, reliable and well-established standard to the market. We’re expecting to see the real products in the near future and looking forward to enabling a robust ecosystem for this brand new specification – SD7.1.
