It's not a good idea to not do journalling for an external drive. No matter |
2 |
how careful you are, it is just a matter of when you will trip up your USB |
3 |
cable in the middle of a write; and then you should just pray that fsck can |
4 |
save your drive without the journal. |

Also, it probably won't hurt using ext4, given that ext4 had several |
7 |
performance improvements over ext3. However, as Theodore T'so - the primary |
8 |
developer of ext4 - said, ext4 is a stopgap until btrfs is ready. IMO, from |
9 |
my experience of using btrfs some time ago, I'd say that btrfs is pretty |
10 |
much ready nowadays. |
