Through the CrystalDiskMark test, SanDisk SD7.0 memory card reads up to 820MB / s, writes more than 470MB / s; copy a 12.67GB file, only 26 seconds; this speed exceeds most SATA6 specificationsSSDSSD. In terms of capacity, the demo displayed is 128GB, and there will be more capacity available in the future.
As can be seen from the picture, the SanDisk SD7.0 memory card is similar to a normal TF card and can be used backwards. If you need to play full speed performance, you need to match it.Mobile phoneCard readers, computers, etc. are indispensable.
In terms of details, there are 2 groups of Golden Fingers in SD7.0, totaling 17; while the average UHS-U1/U3 TF card has only 1 group and 8 gold fingers.
The SD7.0 memory card speed has increased significantly, thanks to the SD Association redefining the UHS-III bus interface, introducing PCIe 3.0 and NVMe 1.3 as the new bus standard. In terms of capacity exploration, SD7.0 broke the existing specification of SD card capacity and increased the theoretical maximum capacity of SD card to 128TB (although not currently implemented).
In addition, during Computex2019, WD Western Digital and JMicron Technology announced a reader solution based on SD7.0 application, which can be connected to PC through USB 3.2 Gen2 latest specification, and finally made onboard or independent. SD7.0 card reader. The demo now shown has been able to fully exploit the speed advantage, let us appreciate the next generation of technology quietly coming.
According to field engineers, Chargerlab revealed that SD7.0 related application products will not be officially put into the market until the second half of this year, and the eager little partners have to continue. As for the price, it has not been disclosed yet. Look at this performance, it will be quite shocking after the listing, let us quietly expect early mass production.
