If a dual layer takes 10 minutes to burn (just a guess, don't own one)
including time to prep the next one, it would take you 1250 minutes,
or just over 20 hours of continuous burning.  That doesn't factor in
the time to chunk up your drive accordingly.  So you'd have to be
offline for at least 2 days.  Your dual layers would cost you about
$125.  A 1TB external drive starts at around $300.  Is it worth all
that time & effort to try and save $175?
