My only complaint is that the manufacturing date is in July of 2021 - almost 2 years ago - which cuts the warranty significantly. I looked up the warranty status on WD's support website and found that it expires in December of 2024 - only 18 months instead of 3 years as advertised.
I don't know what mfg date the new ones are shipping with but if the warranty is important to you I would look for the date before opening the anti-static bag it comes in so you can return it unopened if necessary. You can also check the warranty status using the serial number that is printed on the box.
VERY quiet with half-decent dampening, much more so than other NAS drives in this capacity I've tested. Note that this noise level does vary by capacity; check the spec sheet and remember that decibels are logarithmic.
This drive was easy to install and the RAID rebuilt quickly. The drive is very quiet (can't hear it once it's spun up) and I've had no problems thus far (about a month in).

気になって、こちらのPlusにしました。 何年ぐらい 持つかわかりませんが、箱には3年保証と書いて
あるので安心です。 追伸 今まで使用していた Blueですが、3年10か月程度の使用、8000時間程度で、注意表示を超えて、いきなり異常の表示になりました。最後は、ボロボロで終わりました。
