Product Features
Exclusive NASware 2.0 technology
Our exclusive technology, NASware 2.0, makes WD Red thrive in the demanding
small-NAS environment. By adding WD Red to your NAS system, not only is
everything more efficient and reliable, you can better protect your data
investment.
3D Active Balance Plus
Our enhanced dual-plane balance control technology significantly improves
the overall drive performance and reliability. Hard drives that are not
properly balanced may cause excessive vibration and noise in a multi-drive
system, reduce the hard drive life span, and degrade the performance over
time. (EFRX models only)
The right choice
WD Red is designed specifically for home and small office NAS systems and
PCs with RAID.
Enhanced reliability
Since your NAS system is always on, a highly reliable drive is essential.
With a 35% MTBF improvement over standard drives, the WD Red drive with
NASware 2.0 is designed for the 24x7 environment.
NAS compatibility
Advanced firmware technology built into every WD Red drive, NASware 2.0
enables seamless integration, robust data protection and optimal performance
for systems operating in NAS and RAID environments.
The secret is the next-generation
technology
WD's next-generation NASware 2.0 technology improves NAS storage performance
by reducing common hard drive concerns in NAS systems including concerns for
things like compatibility, integration, upgrade ability, reliability and
cost of ownership that are experienced with a hard drive designed for
desktop computers.
Energy efficient and money saving
We keep power consumption low which keeps your NAS system happy and your
wallet, too.
Lower operating temperatures
