Only a D6 will be able to take full advantage of a CFexpress memory card. For all other cameras it is a waste of money to buy this cards. XQD are double the cost of SD cards and if my D850's had two SD card slots it would have saved me a couple thousand dollars.

All the reviews testing the storage performance of the D6 found that CFe is significantly slower than XQD on the D6, and the XQD performance on the D6 is slightly worse than on the D5. Looks like the storage components of the D6 and the D5 are the same, with the D6 having a smaller buffer. Don't expect the D6 to "take full advantage of CFexpress", it apparently doesn't have the hardware to do so. Not even reaching XQD performance indicates that they simply added CFe support to hardware designed for XQD.

Thanks to the larger buffer, CFe performance on the D5 would probably be better than on the D6. They will not allow that to happen. But who would want to use expensive CFe cards when XQD is faster anyway?
