Should you buy the IronWolf 2 TB?

It's a good match for a 2- or 4-bay box that sits somewhere you can hear it. Drives at 5,400 rpm run quieter and cooler than the 7,200 rpm lot, and they're still quick enough for gigabit. CMR, thankfully. SMR and parity rebuilds don't get on.

Watch out for

Treat that bay rating as a hard limit. Anything larger wants a pro or data-centre drive. You get three years' cover and a 180 TB a year workload rating, both on the light side if the pool's busy every day.

There's no Backblaze data worth quoting here. Seagate's datasheet puts it at 20 dB idle and 21 dB seeking. Power draw is 2.8 W idle and 3.1 W working on Seagate's figures, or 25 kWh a year if it spends the whole year idling. Four of them in SHR or RAID 5 give 6 TB usable, or 5.5 TB once Windows has done its binary maths on it.
