Product Benefits
Professional solutions
Designed specifically with SMB customers in mind the WD Red family has expanded
with the addition of WD Red Pro, which is available for the 8 to 16 bay medium
to large-scale NAS environments. With capacities up to 4 TB, WD Red Pro carries
a 5-year limited warranty and was engineered to handle the increased workloads
from your business.
Exclusive NASware 3.0 technology
Our exclusive advanced firmware technology built into every WD Red Pro drive,
NASware 3.0 enables seamless integration, robust data protection and optimal
performance for systems operating in the demanding NAS environment.
Experienced in NAS
WD Red is a reflection of the most extensive NAS partner compatibility-testing
list that is available on the market.* That means when you buy a NAS enclosure,
you can trust that WD Red will be the most compatible drive available. Our pride
is in our product and our vision is shared with our customers.
Vibration Protection
In combination with 3D Active BalancePlus, WD Red Pro also features hardware
vibration compensation technology which monitors the drive to correct both
linear and rotational vibration in real time, further increasing drive
reliability.
Enhanced Accuracy for NAS
For overall enhanced accuracy for NAS, WD Red Pro is also equipped with dual
actuator technology which improves positional accuracy over the data tracks and
head positioning. StableTrac technology then secures the motor shaft at both
ends to reduce system-induced vibration and stabilize the drive platters for
accurate tracking during read and write operations. Both technologies are
important for larger 8 to 16 bay NAS environments.
8 to 16 Bay Shock Protection
WD Red Pro is equipped with a multi-axis shock sensor that automatically detects
subtle shock events and dynamic fly height technology which adjusts each
read-write function to compensate and protect the data. This combination of
technology
further protects the drives in large 8 to 16 bay NAS environments and increases
drive reliability.
Extended Drive Testing
The 8 to 16 bay NAS environment is very demanding on a hard drive with added
vibration, heat and other factors. This is why every WD Red Pro drive is shipped
with extended thermal cycle burn-in testing which ensure each drive for extended
reliable operation.
Error Recovery Prevention
Built specifically for RAID and NAS environments, WD Red Pro drives come
equipped with error recovery controls as part of NASware 3.0, which prevents the
drive from fallout in RAID applications.
Longer warranty coverage
Complimenting WD Red at a 3-year limited warranty, WD Red Pro offers longer
warranty coverage with a 5-year limited warranty for an even greater peace of
mind.
