A:AnswerThis card works perfect in my Mavic. I mainly got it for my cell phone, but I tested it in the Mavic and it was perfect. I was able to record 4K with no problems also.
A:AnswerCheck the camera owners manual and see if it supports SDXC. I would assume that it is compatible and can be used with a camera. I use mine with a Cannon SX160. It's a micro card so you might have to use the adapter that comes with the card.
A:AnswerI use one of these cards on my Microsoft Surface tablet for extra storage (mostly music and media files). Just realize that any sort of storage ram will eventually break down over time from read/writes, so if you want to preserve it longer I recommend using it with files that don't write very often like music and media files, and have a backup of those files somewhere else just in case.
A:AnswerFrom researching on your Nikon D80, the max capacity that it allows is only up to 32GB. Any more and the system has a hard time using it. You can try to format the SD card to read as FAT32 with SD Formatter (a formatting service used for any SD card to clear/clean cards) and hope that it reads all 64GBs. Looking around more, some people have stated it works, where most have said that it does not. Nikon D80 will see SDHC (up to 32GB capacity) chips and not SDXC (beyond 32GB capacity. IE: 64GB, 128GB 256GB cards).
I would stick with 32GB SDHC cards for your camera and not 64GB SDXC.
Though if you would like to try the FAT32 format trick, you can download the file from their site at

as well as their manual that comes with the camera!
If this works, have fun with your card! If not, I would find another use or return the chip for another 32GB SDHC card.
Hope all the info has helped out!!
