Summary: This drive was a recommended model by Backblaze. So far it has ran circles around the 2 TB Seagate drive it replaced, but that drive did show signs of failure early on (occasionally the PC would not see the drive).
Summary: I will only buy Hitachi drives now. I've had SO MANY Seagate drives fail in the last 10 years, and WD is not much better. I know WD owns the Hitachi drive group now, but I'm hoping they will keep the manufacturing separate from the other division.

Summary: Bought 3 for the NAS. One failed after a few days, and seller replaced immediately. The NAS is down now (for other reasons) but for the short period it was working - the HDDs were working fine, not as quiet as the Baracuda 1.5 TB I had in there before, but they are much quicker.
Summary: Best drives I could get for my ReadyNAS Duo v1. The speed upgrade from the factory drives is night and day. I can now watch and transfer videos/files simultaneously without lag or video stutter. Well worth it.
