A line of highly specialized 3.5″ HDD drives from the American manufacturer Western Digital. They are part of the specialized WD Red server series, belong to the upper price range, and are focused on round-the-clock operation as part of home, office and commercial NAS servers.

WD Red Plus has important features to optimize your server shelf experience. An adaptive compensation system with a shaft fixed on both sides and three-dimensional balancing minimizes the negative effects of vibration. Another important aspect is that the heads are parked only when the power is turned off, which allows the drive to continue working even in standby mode. Well, the built-in NASware technology suite increases the compatibility of WD Red drives with a home or office network, which is connected to numerous PCs, laptops, smartphones, TVs and other equipment with a Wi-Fi connection. All this makes WD Red Plus hard drives ideal for server needs to ensure stable and uninterrupted operation.
