SUMMARY
Nikon DSLR users, particularly those with models like the D850 that use XQD slots, can future-proof their memory card investments by updating to CFexpress Type B cards. These cards share the same physical shape as XQD and are compatible with the D850 through firmware update 1.20. This allows photographers to use the cards in their current DSLR and then seamlessly transition them to future mirrorless bodies that utilize the CFexpress standard. Despite the D850's processor not being optimized for CFexpress speeds, the primary benefit is the card's longevity and compatibility with next-generation cameras, especially as NAND flash memory prices continue to rise.
