Industry’s highest capacity nearline drive
WD RE SATA hard drives are available
in capacities up to 4 TB to suit even
the most demanding storage needs.
Enhanced RAFF™ technology includes
sophisticated electronics to monitor
the drive and correct both linear and
rotational vibration in real time. The
result is a significant performance
improvement in high vibration
environments over the previous
generation of drives.
Dual actuator technology
A head positioning system with
two actuators improves positional
accuracy over the data track(s). The
primary actuator provides coarse
displacement using conventional
electromagnetic actuator principles.
The secondary actuator uses
piezoelectric motion to fine tune the
head positioning to a higher degree
of accuracy. (2 TB and above)
The motor shaft is secured at both ends
to reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations. (2 TB
Multi-axis shock sensor
Automatically detects the subtlest
shock events and compensates to
protect the data.
NoTouch ramp load technology
The recording head never touches
the disk media ensuring significantly
less wear to the recording head
and media as well as better drive
protection in transit.
Thermal extended burn-in test
Each drive is put through extended
burn-in testing with thermal cycling to
ensure reliable operation.
Dynamic fly height technology
Each read-write head’s fly height is
adjusted in real time for optimum reliability.
