1: Software RAID on Linux is way less than impressive. Plus last a I
checked Linux can't handle mirroring a entire disk. Last I looked at
it around a year ago you were limited to only mirroring partitions,
which is a joke from a administrative standpoint.
2: No real impact other than a bad disk won't mean a reinstall.
3: On Linux, go hardware. On FreeBSD it is personal choice.
