    Two 4TB drives in a zero RAID, I expected much more in terms of performance. After a year, one failed. The old 1TB Seagate with PS works faster.
    It's hard to say, I bought it because of its former glory, but I was wrong.
    Questionable reliability

    Чем больше объём,тем больше шума, нагрева и меньше надёжность

    2Тб модель - тихий, холодный, надёжный, в работе 10 шт - у 2х уже наработка более 20 тыс.часов, вся поверхность дисков хорошая, с быстрым временем доступа
    4Тб модель - в ожидании тихий,в работе чуть слышно, тёплый
    8Тб модель - в ожидании тихий,в работе слышно хорошо, горячий до 52 градусов
    2Тб модель - тихий, холодный, надёжный
    4Тб модель - в ожидании тихий,в работе чуть слышно, тёплый
    8Тб модель - в ожидании тихий,в работе слышно хорошо, быстрый
    8Тб модель и более - главный недостаток гелий,он не вечен и постоянно улетучивается через корпус. Непригодны для "вечного" хранения
    Happy with my choice

    good quality product
    I think the main advantage is that it is optimized for consumer NAS. They behave normally at work and remain cool. This is a very good indicator. This model is cheaper than buying the RE series. They are more reliable in operation than desktop models.

    Red Baron

    De jure, WD Red is a hard drive for creating RAID arrays (mirror or serial) and installing in NAS servers. The spindle speed is 5400 rpm, that is, compared to other PC components, it is almost silent. 64 MB of buffer memory to speed up the processing of the smallest files. Sequential read and write is performed at 150 – 160 MB / s, which is quite fast by the standards of low-speed HDDs.

    Round the clock work

    Implemented in Red a number of proprietary technologies WD. First, NASware 3.0 firmware provides 100% compatibility with popular NAS server models, 24/7 operation, and easy RAID scalability. Simply put, you can install additional drives even without having to reboot your PC or NAS server — the operating system will attach them to the shared disk space, as they say, "on the fly".

    Quiet and smooth

    Secondly, 3D Active Balance Plus balances magnetic plates in two planes with precision, thereby reducing vibration and increasing HDD reliability. Finally, thirdly, IntelliPower automatically changes the data transfer rate and the smart caching algorithm depending on the load. Indeed, from our personal experience we can confirm that Red, regardless of the size, are among the quietest 3.5-inch HDDs on the market.

    For home and office

    But de facto, the WD Red is a fairly versatile, quiet and reliable hard drive that's great for a home or work PC as an addition to a fast but low-capacity SSD. That is, whether the scope of its application is not limited to NAS servers alone. WD Red is not suitable except for the role of the main system drive — for this task it is better to choose Blue or Black at 7200 rpm (read and write speed 200 – 220 MB / s).
