Hey everyone,
I need some advice on replacing a failed HDD in our RAID10 setup. One of our four drives has failed, and I'm trying to figure out whether it's just the disk or if there's an issue with the RAID controller itself. My seniors suggested starting by replacing the HDD first, so I'm on the lookout for a suitable replacement.
The original drive was a **Seagate Barracuda 2TB 7200 RPM ST2000DM001**. I've been finding mostly refurbished options, which I'm not too keen on. However, I did come across a newer model, the **Seagate Barracuda ST2000DM008**, which seems to be from a newer generation.
I'm curious if using this newer model as a replacement would be acceptable, or do I absolutely need to match the original one? Any insights would be appreciated. Thanks!

Generally, it's best to avoid Barracudas in RAID setups because they might have played a part in your failure. If you're sticking to Seagate, consider getting a RAID-specific drive like the IronWolf or IronWolf Pro. Also, be aware that the original drive was a CMR drive, which is good for RAID, but the new model you mentioned might be SMR. You want to stick with drives that have CMR, as SMR wouldn’t work well in your setup.
The important thing is having a drive that’s as large or larger and matches or beats the speed of your original. It's also wise to avoid using identical drives, as they often fail around the same time due to similar failure rates.
You can replace it with any drive that’s at least the same size, but I wouldn’t go with a Barracuda. Grab an enterprise drive instead for better reliability.
Size matters, but you also want to keep performance similar. If you're looking for a budget option, how about a refurbished ST2000DM001? They're typically under $30. If you want something better, consider getting two matching enterprise drives for around $50 each. It might be time to look into SSDs for better reliability if this setup is critical.
Thanks for the input! I was thinking about SSDs, but I didn't want to jump into it just yet.
Yeah, upgrading to SSDs would definitely provide better performance and reliability in the long run!
Just double-check that whatever replacement you choose is a CMR drive, not SMR. That's crucial for RAID stability.
Good call! Keeping things diverse can help prolong the lifespan of your RAID setup.
