there is no doubt, that RED vs IronWolf lines have similar basic performance specification (Max. Sustained Transfer Rate)

when IronWolf has 7200 rpm of spindle speed as standard from 6TB capacity, entire WD Red line has 5400 rpm only

both Pro series have same 7200 rpm of spindle speed for all capacity values

same drive bay support (or limitation in case of guarantee):
- up to 8 bay NASes for Red, IronWolf
- up to 24 bay NASes for Red Pro, IronWolf Pro

same workload limit:

- 180TB/y (Red, IronWolf)
- 300TB/y (Red Pro, IronWolf Pro)
From this week we know, what HDD has CMR or SMR technology (for current models only).

Pros for Seagate:
- detailed technical specification easily discovered from web (incl. Latency, Seek time for w/r, density, platters, ...)
It counts, because when vendor hiding such data, there is something strange.

My point regarding useful decision for your valuable data - photos, ...
Check the Seagate Exos or WD Ultrastar series for a comparison with above mentioned HDDs. You can get:
- better performance
- long lifespan (MTBF, Load Unload Cycles), more than 4 times
- workload limit up to 550TB/y (126GB/h in 12h operation mode per 365Days)
- no limitation of bay numbers
- for similar cost of the HDD

when you need just simple storage, then Seagate IronWolf series is better than WD Red = for same cost you will get better performance. Valisd up to 10TB capacity, then you will get similar performance.
