For Linux, this is completely false. You can use a RAID-1 for the root
partition, or use a RAID-1 /boot partition, and a RAID-5 root
Hardware raid only adds expense, bugs, slowness, and makes it harder to
fix when the raid controller does something stupid.
I've never had Linux software raid do something that I couldn't recover
the data from. I've had hardware raids decide to eat volumes where I
put in a disk that wasn't pristine, or decide to fail known-good disks,
or decide to scramble the bits when upgrading the firmware. Not fun.
