In addition to the comments from the others note
- Using fstab for bind mounting works just as well or better in some
cases than symlinks
- You can set things up completely plain-vanilla, test and then move
the folders after.
- USB isn't really that great a connection for daily mission-critical
disk usage
- I recommend e-Sata if it needs to be external
- or even better, internal "hot swap" drive bays that let you swap the
drives out
