I was using this with a Nikon Z6. I'm selling it because I no longer need it after switching to a ZF body. I'll also include a cheap card reader that I was using at the same time as a bonus. There are no boxes, cases, or other accessories. I've never had any operational problems or errors with it, but since it's a used item, please refrain from purchasing if you have any concerns. This is my first time selling, so there may be some shortcomings in shipping and packaging, but thank you for your understanding. - Capacity: 120GB - Transfer Speed (Read): 440MB/s - Transfer Speed (Write): 400MB/s - Interface: USB - Type: XQD Card Reader
