How does the Brother MFC-L2750DW's drum unit compare to its toner in terms of lifespan?

The DR-730 drum unit lasts about 12,000 pages, which is roughly four times longer than the TN-760 toner (3,000 pages) or ten times longer than the starter TN-730 (1,200 pages). This means you’ll replace toner three or four times before needing a new drum, spreading the drum cost across multiple toner cycles.
