How these two compare
Sequential throughput

On a mechanical drive read and write track closely — platter speed and data density set the rate, not the direction — so it is the read figure that separates them, and Western Digital WD Purple HDD 8TB carries the higher one.
Spindle speed
Seagate IronWolf HDD 8TB turns at 7200 RPM, Western Digital WD Purple HDD 8TB at 5400 RPM. Higher RPM shortens the wait for data under the head; lower RPM tends to mean less power draw and a quieter drive.
Cache

Warranty
