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.

The choice of professionals

The WD Red Plus WD40EFPX 4 TB hard drive provides ideal conditions for server systems with increased and round-the-clock loads. Thanks to 3D Active Balance Plus technology, which includes a two-sided central spindle mount and two-axis rotation adjustment based on sensor readings, the device demonstrates high reliability in RAID arrays. This eliminates unnecessary vibrations and imbalance, especially when installing the drive in network storage with up to 8 bays. This solution guarantees an increased service life of the device. An additional advantage is NASware 3.0 technology, which allows you to achieve maximum performance when working with NAS systems and network equipment from various manufacturers.

Video surveillance without restrictions

WD Red Plus WD40EFPX is suitable for streaming recording from surveillance cameras and broadcasting in online and offline mode with virtually no restrictions. The device is capable of processing several dozen streams simultaneously in both directions, which makes it an excellent choice for both home needs and complex video surveillance systems for small and medium businesses. The use of CMR technology and a built-in 256 MB cache ensures high recording efficiency without gaps and data loss. In general, the model has a balanced power consumption, low heat generation and fully meets the requirements of server systems and video recorders.
