I am planning a new home server build and am trying to decide between WD Red drives, Seagate NAS drives or White Label (the rebadged RE4 ones) drives. No matter what, they will be placed in a ZFS pool (probably a 4 drive RAIDZ2) and possibly used as a data store for 2-3 VMs in an all in one install. I have used mostly WD drives in the past, but I am not against other brands if they will perform better for me.
