There have been some solid answers already, so I'll add the option to 
use ZFS - not for boot but for /home at least.

ZFS has some really great features - snapshots, send / receive features 
for duplicating data to a backup machine that's way, way better than 
anything else I can think of:

Only changed blocks get sent. Move a multi GB file to another folder? 
Then rsync sends a whole new copy. ZFS just updates the meta data.

Add a few bytes to a multi GB file? ZFS just sends the changed blocks.


ZFS can self-heal corrupt data if redundancy is enabled (like RAID 1): 
read a block, calculate its checksum, if mismatch read other copy of 
data, calculate checksum, if valid send to user and replace bad copy, if 
both copies bad - warn user.


There are a *lot* of nifty features, it's at least worth investigating 
as an option.
