Assuming reliable backups are being performed (they should be), then
what raid really buys you, aside from performance, is minimized
downtime by saving you the trouble of restoring from backup.

For a family file server, downtime in the event of disk failure may be
acceptable.  If this is the case, LVM may be a simpler approach, and
combined with regular backups, is very suitable.

Raid won't save you from data corruption not related to disk failure.
And since the file server is being accessed on the lan, the
performance bottleneck is likely the network itself, especially if
multiple people are working with lots of data simultaneously, like
large video files, etc.
