That's pretty odd.
Linux RAID is *trivial* to set up, and has a good reputation. I've used
it for years now without issue.
I also had good luck with NetBSD raidframe for about a year.

It's a very reliable filesystem with full data journaling and btree indexing,
and an excellent recovery program as well.
You can also scale the journal features, turning on what you want, which is
IBM's JFS is also a fully journaled filesystem with a focus on data integrity,
and still fast enough for many uses.

It is if you understand its design goals and limitations.
XFS is a metadata journaling system, it does not journal data. It is optimized
for large rather than small files, though it does have btree indexes. It takes
risks with aggressive write caching to gain speed.
I've used it for years without losing a filesystem, but I did lose data
on a few occasions.
