Hello, I’m relatively new to self-hosting and recently started using Unraid, which I find fantastic! I’m now considering upgrading my storage capacity by purchasing either an 8TB or 10TB hard drive. I’m exploring both new and used options to find the best deal. However, I’ve noticed that prices vary based on the specific category of hard drive (e.g., Seagate’s IronWolf for NAS or Firecuda for gaming). I’m unsure about the significance of these different categories. Would using a gaming or surveillance hard drive impact the performance of my NAS setup?

Thanks for any tips and clarifications! 🌻

    The concern for the specific disk technology is usually around the use case. For example, surveillance drives you expect to be able to continuously write to 24/7 but not at crazy high speeds, maybe you can expect slow seek times or whatever. Gaming drives I would assume are disposable and just good value for storage size as you can just redownload your steam games. A NAS drive will be a little bit more expensive because it’s assumed to be for backups and data storage.

    That said in all cases if you use them with proper redundancy like RAIDZ or RAID1 (bleh) it’s kind of whatever, you just replace them as they die. They’ll all do the same, just not with quite the same performance profile.

    Things you can check are seek times / latency, throughput both on sequential and random access, and estimated lifespan.

    I keep hearing good things about decomissioned HGST enterprise drives on eBay, they’re really cheap.
