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?
For a media server speed matters little (5400rpm is plenty), if you’ve only got one drive, warranty is king. Thing is you shouldn’t only have one drive, drives will fail, and warranty doesn’t get your data back, so you plan for it. At the very least, you should look at getting an offline backup as soon as possible, now you don’t care if your drive fails and can get the cheapest ones. Ideally, you also set up a RAID5 (or Unraid, or mergerfs+SnapRAID) on your server, now you just get a replacement drive and rebuild. Remember RAID is not a backup, it doesn’t protect against accidental deletions for example, so you still want the offline backup.
Also, don’t sleep on manufacturer recertified drives, as long as you have a backup they’re significantly more cost-effective.
TLDR: set yourself up so that a drive failing is not a problem.
