F2fs specifically designed for SSD, SD, USB. I found changing my usb and SD cards to f2fs file system meant they were much faster for file transfer. Also safer than FAT (has journaling). This tool is required to format disk as f2fs in eg. gparted. I advise against using the slow and outdated FAT32, though exFAT is comparable to f2fs. Only one thing, on one SD card, copying files doesn't seem to stick (ie the copy process functions, but then I can't see the file when opening SD card again).
