The features of the Western Digital Red 4 TB in detail
The Western Digital Red 4 TB filled with helium and hermetically sealed. Helium is only one-seventh the density of air, which is why replacing air with helium in a hard disk drive significantly reduces the air turbulence caused by the rotating disks. This also minimizes power consumption and temperatures, which allows Western Digital to accommodate more platter in a traditional 3.5-inch form factor.

This design offers a 50 percent capacity gain while still saving up to 23 percent energy. The hard drive consumes only 4.8 watts during operation and runs approximately four to five degrees below the temperature of standard hard drives. With 3.1 watts in idle and 0.4 in standby mode, the remaining power consumption values of the Western Digital Red 4 TB are also very low, which not only benefits the NAS system, but also the wallet.

Attention: Please note that this hard disk model with 26.1 mm turns out slightly higher than is the case with most other 3.5 inch HDDs. If necessary, measure whether the hard drive can fit into your PC, your NAS or into your external hard drive housing.

With 180 MB / s, the limit of the SATA interface is far from exhausted, but the SATA 6G installed here offers not only the advantage of a higher bandwidth. Because the protocol was also significantly refined, for example to increase energy efficiency and optimize the transmission of several simultaneous data streams with high bandwidth.

NAS is an impressive interface that makes it extremely easy to exchange data between different devices quickly and wirelessly. The Western Digital Red hard drives are equipped with NASware. This increases system compatibility and allows seamless integration into existing network infrastructures.
