Excerpt: These were to replace some WD Red drives (from another vendor) which, contrary to their description, were "bulk" drives not subject to warranty. I had no problems registering the drives purchased through B&H with Seagate. The fit into the intended RAID enclosure without problem and were formatted and tested flawlessly. The drives arrived on time and well packed. The drives are quiet in the RAID enclosure.
Summary: I got these for my media/file server. Before this, I was using Seagate Greens in a software RAID, they kept dropping out of the RAID, and reporting SMART failure. I tested them all after replacing them with these NAS drives, and they all appear to be fine. I'm also using a a dedicated RAID controller now. Not sure if it was the software RAID or the fact that I was using Green drives for RAID, maybe a bit of both... No issues with the new drives so far.
Summary: I have been running these drives for about 6 months now without any issues. I set them up in a RAID 1 array and achieve 100MB/s over my network. I will never understand why people use non-NAS drives and in NAS arrays and wonder why they have failures.
Summary: I have owned this drive for almost a year. It has been running 24/7 the entire time using a zfs and I have had no issues with its performance nor its reliability. I just purchased two more and expect the same from them. I think this drive is the quintessential file storage drive for the home user.
Summary: I initially purchased only one of these for my 2-bay NAS but figured that I'll need one more. Installation was easy (I use Lenovo ix2-dl NAS housing) and in few month of usage I didn't have any issues. I hope these HDDs are reliable as they say and that I won't experience failure since I put then in RAID 0 and I want to transfer to them all movies/shows I have....
