Our Take

Best for: Small business owners and home users building reliable NAS storage.

The included 5-year warranty and Rescue Data Recovery service add peace of mind. 15, making it a solid buy for current needs. The only tradeoff is the price per TB compared to desktop drives, but for NAS reliability, it's worth it.
