Western Digital Red Pro, SATA 6G, 7,200 rpm, 3.5 inches - 4 TB [WD4002FFWX]

The color for NAS! The previous Black, Blue and Green plate series is joined as another color "Red". The plates from the Red series are specially designed for continuous operation, a meanwhile very important target group. This makes them predestined for use in NAS systems and RAID setups. With 128 MB of cache, this WD Red Pro disk offers more than enough reserves for this purpose.

The Red Series hard drive featured here is a new high-performance, high-speed NAS hard drive with a storage capacity of 4TB. This is a version of the Red with modern SATA 6G connector.

The plate is also filled with helium and hermetically sealed. Helium has only one-seventh of the density of air, so replacing air with helium in a hard disk drive significantly reduces the air turbulence caused by spinning disks. It also minimizes power consumption and temperatures, allowing Western Digital to accommodate more platters in a traditional 3.5-inch form factor.

This design offers a 50% capacity gain while still saving up to 23% energy. So the hard drive consumes only 9.1 watts in operation and runs about four to five degrees below the temperature of standard hard drives. With 7.1 W in idle and 1.0 in standby mode, the remaining power consumption of the Western Digital Red 4 TB is very low, which not only benefits the NAS system, but also the purse.

Attention: Please note that this 26.1mm hard drive model is slightly higher than most other 3.5 "HDDs. If necessary, measure whether the hard drive fits into your PC, NAS, or external hard drive enclosure.

At 202 MB / s, the limit of the SATA interface is far from exhausted, but the SATA 6G built in here not only offers the advantage of higher bandwidth. This is because the protocol has also been sharpened, for example, to increase energy efficiency and to optimize the transmission of multiple simultaneous data streams with high bandwidth.

NAS is an impressive interface that makes it easy to wirelessly swap data between devices quickly and easily. The Western Digital Red hard drives are equipped with NASware 3.0. This increases system compatibility and allows seamless integration with existing network infrastructures.

3D Active Balance Plus in WD Red is an advanced mass balancing technology on two levels. Overall, it improves the performance and reliability of the drive. Hard-drive hard drives can cause excessive vibration and noise in a multi-drive system, reduce hard drive life, and slow performance over time. As a result, Western Digital also advertises its 4TB hard drive with a tremendous MTBF of one million hours.
