Seagate has been the most unreliable drive for me. A lot of youtubers support Seagate probably cuz they give away free drives to them. All my Seagate desktop and NAS drives have failed in 1-2 years. I have had a Ironwolf 6TB drive fail in under 6 months.
WD/HGST has been quite reliable for me. I still use the HGST 6TB drive I bought years ago along with the Ironwolf 6TB. Only thing I hate is the excessive heat and noise.
Toshiba is my new favorite now. I have used their 6TB drives for a few years now and they are quite good. I prefer Toshiba MG series drive. They run cooler and are not too noisy. And last quite long.
