I guess they're all good, uaed to buy the cheapest, but at the moment that's not really possible.

In my old NAS I still have Hitachi, they're running for over 12 years now, 24/7.

Then I bought Exos drives, the 8TB ones I paid 140? each at the time, wish I had bought more.

Now for the expansion I bought Ironwolf Pro 8TB, they were 285? each, so over double the price than the Exos at that time, but those were now the cheapest I found, the non Pro were only 5-10? cheaper. Exos were slightly more expensive.

The 4x16TB I have are also Exos drives.
