Not entirely true. I have a $600 SAS controller that wont support 4TB drives sitting here unless it's flashed with a firmware mod. It's also about the same age as most of everything OP was looking at and talking about before. I also have plenty of NF2 motherboards sitting here that wont support a 4TB disk.
A LOT of the issue comes down to 4TB disks mostly using 512e, the sata controller firmware must support those disks, otherwise those disks will likely show up as right under 2 or 3TB depending on firmware.
