It is a complex beast. It needs some maintenance and performance will degrade without it.

I've never lost data to it, I've never tried the soft RAID modes it has though, but I've experienced it making a system almost unusably slow. SUSE out of the box with it automates a lot of it and it's pretty remarkable. Transactional mode if you want it seems like a game changer for some servers and the snapper stuff has saved my bacon a couple times. It's getting there but like I said, it needs some maintenance and just formatting a partition with it is likely the wrong way to experience it.
