45drives is... bad. I cannot understand why people would use them- particularly for homelab. Three SC846 24x3.5" 4U can be had for no more than $400/ea and, theres 36bay versions.

Because then you need three times the rack space. What you don't spend one-time for the hardware you'll spend extra every month for rack space, connectivity, cooling, power etc.
You might use that budget for redundancy, for example.
60 drives in 6U is a crap ton of weight.
