What is the memory card of Nikon digital camera?

The memory cards of Nikon digital cameras are as follows:

The XQD memory card of Nikon camera is a memory card format using flash memory. Based on PCI Express specification, the writing speed is allowed to exceed125mb/s ... xqd is designed for the shortcomings of CF card, with smaller size, faster writing speed and larger capacity. Although the CF card has been replaced, it has not been completely replaced for a long time.

XQD cards and CF cards are aimed at high-end users, and their share in the low-end market is even lower than that of SD cards that are more people-friendly. In the future, SD Express memory card specification supporting PCI Express and NVMe transmission interface will be added to SD card, which can increase the reading and writing speed to 985MB/s at the highest, and support the memory buffering characteristics of HMB host in NVMe protocol.
