Using Two Memory Cards - Nikon D750 User Manual

Using Two Memory Cards

When two memory cards are inserted in the camera, you can use
the Role played by card in Slot 2 item in the photo shooting
menu to choose the role played by the card in Slot 2. Choose
from Overflow (the card in Slot 2 is used only when the card in
Slot 1 is full), Backup (each picture is recorded twice, once to the
card in Slot 1 and again to the card in Slot 2), and RAW Slot 1—
JPEG Slot 2 (as for Backup, except that the NEF/RAW copies of
photos recorded at settings of NEF/RAW + JPEG are recorded
only to the card in Slot 1 and the JPEG copies only to the card in
Slot 2).

"Backup" and "RAW Slot 1—JPEG Slot 2"

with the least amount of memory. Shutter release will be disabled
when either card is full.

Recording Movies
When two memory cards are inserted in the camera, the slot used to
record movies can be selected using the Destination option in the
