Western Digital 4TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" - WD4005FFBX

I use it in a Sabrent Disk Doc. Haven't yet tested its speed, but so far seems reasonably fast. The thing I noticed is that in the disk doc, its vibrations can be felt all over the desk.

First, I ordered these during prime days. I never got my order. I waited 3 weeks for them to ship. They showed they made it to the local Amazon distribution center. Then, I got notice the order was canceled due to box being damaged. No worries, just send me 3 more. Amazon wouldn't do it. So, I will no longer consider Amazon for PC supplies like hard drives. New Egg was excellent and I actually got 20TB drives for what I paid for these. Now, concerning WD drives. If you put these in a Synology NAS, you will get notifications at 3 years that the drives are no good. There is some kind of baked in notification deal that causes these drives to do this. I'm glad I went with Exos drives (20TB) vs. these. Very happy with those drives.

Installed in my NAS running with raid1, it is quiet enough at night, I just put it in my living room and I can barely hear the noise when it is reading/writing large amount of data. The only drawback is it was too large and took too long time the complete the raid 1 building. No other complain at all.
