Following the launch of CFExpress and its gradual popularity, with the improvement of camera pixels and video specifications of various manufacturers, the storage aspect is gradually tilted towards CFExpress storage. Recently, the president of the SD Association announced the new SDExpress8.0 specification. SDExpress8.0 is based on the PCIe4.0 standard using NVMe technology, and can reach 4GB/S per second in terms of theoretical data transmission.
SDExpress8.0 represents the current cutting-edge technology of high-speed memory, based on The PCIe4.0 standard enables SDExpress8.0 to achieve a transmission speed of 2GB/s per channel, and can provide up to two channels at the same time.
In terms of appearance, SDExpress 8.0 will be adopted by the previous SDExpress The same specifications and compatible with previous products. SD Association Note Association Sakamoto Hiroyuki said: “With SDExpress 8.0, anyone can shoot slow motion videos or high-speed motion photos, ensuring the quality of the photos, but also being more portable in terms of storage, recording and playing back 4K and 8K videos. It will also provide great convenience.”
Editor’s point of view
Although there are new standards in SDExpress, it still requires a certain amount of theoretical data transmission in practical applications. Time, and presumably, the price will be much higher than the current affordable SD card, which also means that SDExpress memory card can not completely replace ordinary SD card in a short time.
