64GB micro sd on Arduino UNO

It is possible to add 64gb mSD card on Arduino UNO?

If I format the card fat32?

It probable take a life time to write it full

You can use an SDXC card that has been formatted FAT32.

SD.h seem to work. It uses a very old version of SdFat that I wrote before SDXC cards existed so it has not been tested.

I do test newer versions of SdFat with SDXC cards. SdFat has an SdFormatter example that formats SDXC cards FAT32 with optimal file system layout.

Windows and the SD Association Formatter insist on formatting SDXC cards exFAT which won't work.

You could use Linux or Mac OS but the layout will not be optimal. You should use 32 KB clusters.
