using it with unreliable power or hardware.
This is not correct. XFS has had several improvements over time. XFS
journals metadata updates and not data updates but that is exactly the
case for Ext4 as well (Btrfs does the equivalent of data journaling but
it is still experimental).
A number of early Ext4 issues were actually fixed by following the same
working model as XFS. Look up sync on rename for example. In short, XFS
is no more prone to data risks compared to Ext4 on any recent
distribution. Of course, if you really value your data, you should have
backups anyway.
