Just get the original: Seagate Exos. With a MTBF of 2.5 Mio hours, they are twice as „good“ as Ironwolfs.
Probably identical to a Seagate Exos with a 400% Dell Markup
If it’s anything like Dell, they’ve taken something and made it worse. Wouldnt surprise me if they reduced the read rate or something similar to make them cooler
They are reliable as other enterprise drives from WD and Toshiba. Really not much to say here, check also if they have valid warranty.
