Working great with my Synology NAS. Didn't need a ton of a capacity, and this fits the bill.

Great Drive

I have a new EXPENSIVE Dell XPS computer but even with the larger hard drive I need more space. Research and chat with Dell brought me to this drive. It was very easy to install however, there is one problem. It was divided into 2 partitions. Dell had no idea as to what to do about it but when I called Seagate, they were great and knew exactly what to do. Partitions merged and all is well. I would recommend it.

I have ben working on, building, and customizing computers for about 20 some odd years, and Seagate is one of my most dependable hard drives, so it is always my first choice, and this one seems to hold its reputation.

No Problems - So Far anyway

Bought two HD to replace older drives in NAS that were beginning to fail in RAID 1 setup. No problems so far. Have only been in use less then one month. But to be fair I do not expect any major issues from this point, as they passed all testing and are operating correctly to date.

Has been a solid drive for me

By Brett

I have been using the iron wolf NAS drives for 6 years or so now, and have three of this model. The have been rock solid drives for me with minimal failures. Actually I don't there have been any to date. I am sure there will be one now that I said that. Anyway, if you're running a NAS or a NAS-like load, I highly suggest these drives.
