Best file system for storing devices to be used with Trisquel Flidas

My basic understanding is that the three main options are:

• XFS: good performances with large files (a few MB is already large); cannot be shrunk (if needed, you can always delete the partition, recreate it smaller, and restore from backup);
• ext4: a little less efficient with large files but super stable (it is the most used);
• Btrfs: supposedly wonderful (full of nice features in particular) but we have been waiting for a stable version for a dozen years now.

I use Btrfs because it transparently protects data from bit rot and has a very storage-efficient backup solution built-in. No stability issues so far. Then again, I've been using Trisquel for less than three weeks.

@Magic Banana: Thank you for your comment
@Centurino: Thank you for your comment.
@Jaret: as far as I can remember it means data corruption due to aging of the storing media.

ext2 for flash media and ext4 for hard disks. I sometimes use NTFS too. (GNU/Linux has better NTFS support than Losedows.)

I use BTRFS on any drive aside from my OS. For my OS I use whichever the installer uses by default unless it gives me a choice (usually EXT4 although Trisquel uses XFS I believe). I haven't experienced any severe issue on any file system I have used over the years. Maybe that makes me lucky. I choose BTRFS when I can because I'd rather have a feature and not need it rather than the other way around and as far as stability goes I haven't experienced a reason not to use it yet. That being said it has been in development for a while so maybe I just joined after all the craziness ended. Overall use what you are comfortable using, what you know how to setup; maintain; and troubleshoot.
