The fstab file is used to define how disk partitions or remote file systems are mounted into your computer. Removable drives such as USB drives or SD cards are not shown there, because if they were, your system would complain at boot that it can’t find the requested USB drive. About F2FS having double the storage space of btrfs. In all honesty, it doesn’t make sense to me. Do you mean it shows you potentially being able to store 80 megabytes if you can get compression working or does it just show 80 megabytes instead of 40, after formatting the file system?

The free space that I mentioned is both what Linux Mint’s file manager states and is what both files systems can hold on the SD card when compression is disabled. If I format the device to BTRFS and disable compression, I can only put 40MB of files onto the SD card. If I format the SD card for F2FS, it can hold about 80MB worth of files. If I format the SD card to BTRFS but enable compression, it says 40MB but it can hold around 100MB worth of files (at least with the files I’m testing). From what I’ve read and seen, if I can get compression working in F2FS, it’ll still say 80MB but probably hold around 200MB of files since, according to the documentation, both file systems support the same compression methods.
