JFS has great data recovery support compared to other file systems. As long as the file system journal writes are kept current regularly, you'll rarely experience data loss.

It's no ZFS, but it's better than BtrFS is currently.

I've been using ext3 and ext4 since ReiserFS was dead back in the day. You got me curious and it's a little off topic, but JFS journals metadata only which makes it faster? And I don't know much about ZFS.

How to use TRIM with JFS? "on the go" or using cron/systemd to schedule running fstrim? I've read on ext4 fs, discard slows down SSD so, distros like Ubuntu by default if detects SSD's configure fstrim scheduled job.

If I go with JFS, how to configure TRIM?
