WD®, a Western Digital (NASDAQ: WDC) company and world leader for storage deployed in datacenters, today announced availability of its innovative  WD Se™ line of hard drives, the  first designed for scale-out datacenter deployments. Built on an  enterprise-grade platform for reliable 24x7x365 datacenter operation, WD Se is  tailored to deliver the right combination of performance, reliability and  robustness for large-scale replicated environments, mid-sized network attached  storage (NAS) deployment, and backup/archiving applications.
 
     WD Se is a true  enterprise-class drive with the right blend of affordability and capabilities  to address the massive growth of semi-structured data, which is accelerating  the scale-out of datacenters of all sizes. Now shipping in capacities up to 4  TB, the new WD Se hard drives enables customers to balance their data growth  challenges in multi-drive enclosures without compromising enterprise-class  features.

      “Today’s cloud datacenter installations  require a cost-effective way to build large-scale storage systems, while  maintaining the 24x7 reliability necessary to minimize total cost of  ownership,” said Richard E. Rutledge, senior vice president of WD’s datacenter  storage business unit. “WD’s utilization of vast amounts of manufacturing and  engineering data has forced us – like many other companies – to use map-reduce  methodologies to effectively analyze our data. The WD Se hard drives are  used in our own big datacenter, where we have gained real-world experience with  Apache™ Hadoop®.”

     WD Se drives also address the fast-growing  SMB to mid-range network-attached storage (NAS) market. The robust  enterprise-class design and higher workload capabilities for SMB-focused  6-bay-plus table-top NAS units and rack-mount multi-tenant NAS solutions with  up to 24 bays, provide NAS integrators a complement to WD Red™ hard  drives, which are for small NAS systems. WD’s other  datacenter hard drives – WD Xe™ and WD Re™ – round out  the high-end of the NAS market, offering higher durability and performance for  large-scale rack-based NAS systems. Together, WD Se, WD Xe, WD Re and WD Red™  provide a total portfolio of robust storage devices to match every size and  scale of NAS deployment.  
    
     In addition to undergoing at least  5,000,000 hours of functional and thermal testing and over 20,000,000 hours of  additional testing under actual workloads in server and storage systems, WD’s Se  hard drives feature: 

• A  dual processor for twice the processing power to maximize performance; 
• Enhanced  Rotary Acceleration Feed Forward (RAFF™) technology that includes sophisticated  electronics to monitor the drive and correct both linear and rotational  vibration in real time; 
• Dual  actuator technology improves head positional accuracy over the data track(s); 
• StableTrac™  whereby the motor shaft is secured at both ends to reduce system-induced  vibration and stabilize platters for accurate tracking during read and write  operations delivering a consistent level of performance for applications; 
• Multi-axis  shock sensor automatically detects the subtlest shock events and compensates to  protect the data; 
• RAID-specific,  time-limited error recovery (TLER) prevents drive fallout caused by the  extended hard drive error-recovery processes common to desktop drives, and; 
• Dynamic  fly height technology where each read-write head’s fly height is adjusted in  real time for optimum reliability.
