I bought two Seagate IronWolf 8TB and both of them seems ok, but 1 is making a little bit more noise on spin-up/boot-up... a little clicking sound.
I read/write 70-100mb/s with this HDD but SMART report low raw_read_error_rate: 78, Worst 64, Thresh: 44.
the other one looks good with 100,100, 44.
Should I be worried and return it? Or is it safe to use in my Synology? (SHR1)
I contacted Seagate for fun and they suggested to run SeaTools for DOS (I'm under linux obviously), but it seems like it's running a basic "long" SMART test. Nothing special there.
I'd strongly recommend you check what does the SMART attributes say about this particular HDD if you run the manufacturer's brand-specific tool, @Jay, just like their support suggested. If the HDD fails any of the Short or Long tests, then you should definitely be worried. If clicking noises are present, then it's also possible that software diagnostic tools might not be able to detect the issue, if it's hardware-related. I'd strongly recommend you backup all your data from the NAS. If the issue is physical damage, then I'd definitely consider replacing the HDD. Hope this was helpful. – SuperSoph_WD – 2016-11-09T10:21:37.590
