WD Se  
Datacenter Capacity HDD  
Optimal Storage for NAS and Scale-Out Architectures  
WDs Se hard drives provide an ideal solution for  
scale-out datacenters, delivering a cost-effective combination  
of performance, reliability, and workload capability while  
maintaining the hardiness of a true enterprise-class design. All  
WD datacenter storage devices are designed from the ground  
up to deliver optimal performance and maximum data integrity  
while running 24x7x365 in demanding multi-slot environments.

Product Benefits  
Cost effective enterprise-class  
storage  
Get the right blend of performance,  
reliability and capacity and keep your  
total cost of ownership low.  
Dynamic fly height technology  
Environmentally responsible  
NoTouchramp load technology  
Each read-write heads y height is  
adjusted in real time for optimum  
reliability.  
In addition to being RoHS compliant,  
these drives are built with halogen  
reduced components.  
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.  
Vibration Protection  
Enhanced RAFFtechnology  
StableTrac™  
24x7x365 reliability  
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 and above)  
Thermal extended burn-in test  
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.  
Choose the storage foundation  
specifically designed for SMB to  
high-end NAS and large-scale  
datacenter replication environments  
running 24x7x365.  
Each drive is put through extended  
burn-in testing with thermal cycling to  
ensure reliable operation.  
Multi-axis shock sensor  
Advanced Format (AF)  
Maximum capacity for hyperscale  
environments  
Build a massive data footprint with  
capacities up to 4 TB - 144 TB per  
square foot.  
Automatically detects the subtlest  
shock events and compensates to  
protect the data.  
Technology adopted by WD and  
other drive manufacturers as one of  
multiple ways to continue growing  
hard drive capacities. AF is a more  
efficient media format that enables  
increased areal densities.  
Dual actuator technology  
A head positioning system with two  
actuators that 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.  
RAID-specific, time-limited error  
recovery (TLER)  
Prevents drive fallout caused by the  
extended hard drive error-recovery  
processes common to desktop  
drives.  
Dual processor  
Twice the processing power to  
maximize performance.  
Applications  
Ideal for bulk cloud storage, replicated environments, content delivery networks (CDNs), SMB to high-end network attached storage (NAS), backup and archiving.  
The WD Advantage  
WD puts our datacenter products through extensive Functional Integrity Testing (F.I.T) prior to any product launch. This testing ensures our products consistently  
meet the high quality and reliability standards of the WD brand. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs,  
operating systems and drivers to ensure an even greater level of quality, reliability and peace of mind.  
WD also has a detailed Knowledge Base with helpful articles and software utilities. Our customer support lines have longer operational hours to ensure you get the  
help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.
