Beginner question: Searching for my first dedicated server setup, and I have no idea what to look for in a hard drive. I see a huge difference between drives of the same capacity, so what makes the difference? I am looking to eventually have a media server that can run “-arr” programs, Jellyfin, Immich, sync music, books, etc.
What are the factors I should be paying attention to other than capacity? Is it a lot of branding and smoke and mirrors, or will I see a significant change in performance/reliability with different drives?
Has Seagate improved? After having multiple Seagate drives fail, I did some research on failure rates and Seagate was way worse than every other brand. Since then I have only been buying enterprise-grade WD drives. However, I did my research almost ten years ago and a lot could have changed since then.
Any difference you personally experience between the three big brands is meaningless. For any failed HDD you have there’s going to be another person who swears by them and has had five of them running for 10 years without a hitch.
But whatever’s cheaper in your area and stop worrying. Your reliability should be assured by backups anyway not by betting on a single drive. Any drive can fail.
Backblaze regularly releases failure rate statistics of their drives, and it’s often a big enough dataset to be quite meaningful. I haven’t been keeping up with it lately, but there certainly was a period of time where there were substantial differences in the failure rates of different manufacturers.
So while you do still need to have drive failure mitigation strategies, buying more reliable devices can definitely save you time and headache in the future by having to deal with failures less frequently.
It’s impossible to tell how meaningful Backblaze’s numbers are because we don’t know the global failure rate for each model they test, so we can’t calculate the statistical significance. Also there are other factors involved like the age of the drives and the type of workload they were used for.

That’s a recipe for sorrow. Don’t waste time on “reliability” research, just plan for failure. All HDDs fail. Assume they will and backup or replicate your data.
All SSDs will die too. Not saying you meant or implied that they wouldn’t, just clarifying for anyone who may not be aware. You’re spot on with “plan for failure”.
Yes, Seagate had a bad run of drives. But that was only certain models, and like you said, years ago. WD had a similar bad run after Seagate recovered, and currently they’re all roughly equivalent. But you can find Backblaze’s data somewhere if you want to read numbers.
Bottom line, there’s always a failure risk, just be prepared for it.
It’s not that Seagate improved (which it may have), it’s more that WD has noticeably declined. It’s not a race to the bottom (yet), but there’s effectively no competition any more, so they aren’t incentivised to improve quality.
