3D Active Balance Plus
Our enhanced two-plane balance control technology increases the overall performance and reliability of the drives. Hard drives that are not properly balanced can cause
excessive vibration and noise in a multi-drive system, shortening the hard drive’s useful life and degrading performance over time.

Environments that operate 24 hours a day, seven days a week
Since your NAS system is always running, choosing a reliable drive is essential. With an MTBF of up to 1 million hours, WD Red Plus is designed for environments that
operate 24 hours a day, every day.

Desktop drives versus WD Red Plus
Choose the right drive specifically designed for NAS for your system, with a range of features that will help protect your data and ensure optimal performance. Consider the
following factors when choosing a hard drive for your NAS:

- Compatibility: unlike desktop drives, these drives have undergone specific compatibility testing with NAS systems to ensure optimal performance.
- Reliability: the always-on environments of NAS or RAID systems involve high temperatures. Desktop drives are not usually designed for these
conditions or tested accordingly, whereas WD Red Plus drives are.
- Error recovery controls: WD Red Plus hard drives are specifically designed with RAID error recovery controls, which help reduce system failures in the
NAS.
- Noise and vibration protection: designed to operate independently, desktop drives typically offer little or no protection against noise and
vibrations that affect multi-drive systems. WD Red Plus drives are designed to excel in NAS environments with multiple bays.
