Should you buy the IronWolf Pro 30 TB?
This is the one to look at once you're past eight bays or the array's busy all day, because Seagate rates it for 550 TB a year and doesn't care how big the box is. Seagate backs it for five years, which is a long time in drive terms. Recording is CMR, the right kind for RAID and ZFS.
Watch out for
Being 7,200 rpm, it's in the noisier, warmer class of drive, and you'll want it somewhere you don't sit.
There's no Backblaze data worth quoting here. On paper it makes 28 dB at idle and 32 dB seeking. Seagate lists 6.8 W at idle and 8.3 W working, which comes to 60 kWh a year for a drive that idles around the clock. Four of them in SHR or RAID 5 give 90 TB usable, or 81.9 TB once Windows has done its binary maths on it.
