I wouldn't use a journaling file system on USB sticks, it adds a bunch of unnecessary writes.
For Linux only USB sticks, I use ext2.
Better ext4 without journal: Source: http://www.sysresccd.org/Sysresccd-manual-en_How_to_install_SystemRescueCd_o... If you are using SystemRescueCD-1.2 or more recent, it's recommended that you use an ext4 filesystem with the journal turned off (this is possible with Linux >= 2.6.29). USB sticks are Flash filesystems and this type of memory only supports a limited number of writes. Journaling filesystems will make many writes at the same location (where the journal is stored). Therefore, to extend the lifespan of the memory we should limit the number of writes. Here is how to use ext4 with the journaling turned off: mke2fs -t ext4 -O ^has_journal /dev/sdf1 Note 2016-03-12: tune2fs -O ^has_journal <ext3/4-device>. You could also use ext2 but it does not support extents, and then it requires more accesses to read/write large files to the disk. -- Cheers / Saludos, Carlos E. R.
