No, XFS will not lose any data that the application has committed to the
disk.
Improperly written applications and/or improperly configured systems
might have issues with recently written files losing data.
FWIW: I have never lost data with XFS, neither on home computers nor in
SAN environments (in the presence of link/path failure).
Be sure the read the FAQ, especially the section about write cache on
dekstop/consumer HDDs.
Just my opinion as an XFS user, your mileage might vary.
