I've considered RAID before.  For what I have here, doing regular
backups is enough, I hope.  Right now, I backup family pics from my
camera, documents and all the videos, which is a LOT.  If a drive were
to fail, at least I have the backups to go to and would lose little if
anything.  Since I backup pretty regular, I could still recover most
everything that may not have made it to backup. 

I'm on a limited income and this is just a home system.  One thing I try
to do is to find a good way forward first, then do something.  That way
I don't do something that costs money, realize I did it in a bad way and
then have to spend more money doing it again and have parts that I will
likely never need or use again.  I try to skip the worthless part when I
can.  ;-) 

That said, when I do get some drives and they are installed, I'll likely
be asking questions about btrfs, zfs, xfs and anything else that may
apply.  Currently I use LVM and ext4.  I like it pretty well but that
doesn't mean there can't be something better out there.
