One of the two drives I ordered was dead out of the box. The other worked fine. Called B&H and then sent a new one out immediately. A bit of a hassle in that the quickest way to get it is for them to charge it as a new purchase on your credit card and then reimburse you when you send the faulty...

I have two Netgear NAS systems and they were populated with 2TB WD "Green" drives which performed well enough. Once I needed to expand the required space I decided to try the 4TB "Red" drives (the NAS systems can't handle the 6Tb ones :( ) and it was a good choice.

I'm currently using these drives in my NAS and my Server. They run beautifully, without over heating and transfers are very fast and reliable. I have an personal VM server running with these drives in a raid config! Love love love it!

Mechanical hard disk drives have been around for decades now but it wasn't until the introduction of the first NAS (network attached storage) and digital NVR (network video recorder) models that the need for different models was even considered by manufacturers.

Can't find my original reviews, so figured I'd do a new one. Brief setup of NAS (all are WD Reds): 1 set of 5 2TB jbod (not on all of the time), 2 raid 10s with 4x4TB drives each (on 24/7). The jbod was set up first and a year or so later the raid 10s were added. Finally, a drive went bad.

reliable - lots o' space -quiet

- one finally went bad

These came recommended by a friend to use for a NAS System. I bought also the Qnap TVS663 (6 bay system) and they are working great in a Raid 5 scenerio. I'm tired of having o spend 1000.00 to have a drive restored. The average cheap store drive I will never buy again.

Not working / corrupted and returned the disk to WD for replacement. Packing was not sufficient and loose packing.

Disc arrived for the ReadyNas Nas storrage and have worked without and problems since install - 3 weeks ago So no early life failures.

Swapped out an old 3tb green drive for this. Western Digital has the best reputation and the drives are affordable.

I haven't seen any issues with them yet. Just some warnings of the Pending Sector count in the SMART readings for one disk. (Likely due to sudden power outages) Highly recommend buying this brand.

I have four of these HDDs running and have had two of them running 24/7 for almost three years
