This is a 120GB 64GB XQD memory card made by Nikon. It comes with one card case. - Brand: Nikon - Capacity: 120GB 64GB - Type: XQD - Connection: USB 3.0 - Card Reader: None I used this with a Nikon Z6. The Z6 is known for its single slot, but I owned two memory cards and always kept one in a card reader and the other in the camera body. As a result, I never forgot to insert a card, and I highly recommend carrying two cards.
