File system fragility was indeed still an embarassment of many UNIX-derived file systems, up to twenty years ago and perhaps until more recently, but this is no longer true today.

Even in the early 2000's, there was one UNIX file system, the FreeBSD UFS with "soft updates", which was completely immune to computer crashes caused by power failures or by anything else, at a time when the journaled file systems of Linux, and also NTFS of Microsoft, were still buggy enough that power failures could result in bricked computers, despite their claims that journaling should protect against this.

But since then, most bugs have been fixed and now at least for XFS I know with certainty that it can pass through numerous power failures without any problems and with no filesystem corruption.
