Purchased drive for an application that constantly writes content. Read many reviews for both Western Digital purple and Seagate Skyhawk. The reviews were pretty even and Western Digital had a larger 512gb buffer and slightly cheaper. Please note, we purchased the 14tb drive and have 13tb usable after formatting. Please keep this in mind for space planning.Performance has been great. Watching disk queue length and not seeing bottlenecks at the disk level.Longevity is unknown right now. If we experience a premature failure or significant change in drive use experience we will update our review.Right now we are very happy with the drive and have plans to buy more.

I have a lottttt of data so I got this. I did not realize the transfer rates on 3.5inch spinning drives have gone up. With a USB 3 adapter/reader dock this was transferring over 100mbps. It makes the spinning drive sounds that these make, but it is actually quit quiet. I use it exposed versus enclosed so it is a little more clicky sounding, but sound wise, if it were enclosed, it would probably be unnoticeable. Plus, it doesn't sound that bad - I actually miss the sound of data moving around haha. I would need it to be used for years to really write on reliability as I have neevr owned these, but looking at the specs, this appears to be a similar design, if not the same drive as their commercial grade drives for business.

I always try to go for the best and I take my data integrity very seriously which si why I chose this specific model. The specs that relate to reliability were the highest I could find at a reasonable price point so I am not disappointed. It actually stays quite cool as I transferred multiple terabytes worth of data at a time and it never really got hot, just warm - and this was in an open dock without a fan or active cooling. When I need to access data or write, it is very quick and never gives me trouble. I am pretty sure I will have this for years - especailly as I always get an overkill for my needs to ensure reliability and longevity.
