Pros: Worked with no issues, large capacity, pretty fast for mechanical drives

Cons: Not the quietest drives I have ever used.

Overall Review: I wanted to add a large amount of reliable storage to my home network on a budget. This seemed to be the best deal available for large capacity drives at the time. I paired two with a Synology DS220j. These booted and formatted with Synology Hybrid Raid (SHR) in a few minutes with approximately 12.6 TiB total capacity. All in all, a great solution with no drama. For those of you in the previous reviews who are bad at math, and are complaining about the storage capacity, google "14 TB in GiB" for a helpful conversion. All hard drive manufacturers have been calculating advertised capacity in powers of 1000 since time immemorial. These drives are showing the exact capacity that I would expect on my NAS in powers of 1024 (13039 GiB or 12.7 TiB)
