Seems good, quiet enough, runs cool enough. No serious smart data problems. The only thing is that the drives have way more than 100 power on hours, around 1500-2000. This is kinda expected for the price and age of the drive, ~1 year old. The manufacturers warranty is as advertised, until 2022. So overall, the price, no bad smart data, combined with the manufacturers warranty these drives seem like a good deal.
All three drives work great in the RAID 5 configuration in my Win 10 PC.
Exactly what I want it. I’m always looking for hard drives for my NAS.
