I don't like RAID-5 either. But you said you were storing movies, right?

And like Bryan, I don't like big partitions unless absolutely necessary.

Let's say you sliced each disk into 4 primary partitions and build four 
RAID-5 drives: for n in 1..4; md$n=raid5(sd{a,b,c,d}, $n);

Mount these as /data$n or similar.

So fill up each partition, and when it's full, mount it read only. You 
can switch to write mode with the mount -o remount,rw command and back 
again with mount -o remount,ro.

Even if writable, Don't Forget To Use NOATIME!
