That's a feature of Sencha ExtJS [1]. Synology didn't do the heavy lifting there.

Which is just mdadm with extra steps. (Create a RAID array spanning all devices up to the size of the smallest device; repeat with the remaining space as long as there are at least two devices; create a JBOD of those arrays.) It's a kind of hokey approach, honestly.
