Sounds like a familiar statement.
RAID-10 doesn't offer much in terms of better redundancy, just faster write speeds. You can lose at most 2 disks with 4-disk RAID-10 however you only need to lose 2 disks in some cases to kill your RAID. For media, RAID-6 would be more reliable and better geared for what he wants to do. RAID-10 makes more sense if you're going to be doing write-intensive work like video editing or running a database server.
