Western Digital Corp., one of the world’s largest hard drive makers in the world, has announced availability of its WD Se line of hard drives, the first designed for scale-out datacenter deployments. Built on an enterprise-grade platform, WD Se is tailored to deliver the combination of performance, reliability and robustness for large-scale replicated environments, mid-sized network attached storage (NAS) deployment, and backup/archiving applications.

WD Se will be available in 2TB, 3TB and 4TB capacities. The drives feature 7200rpm spindle speed, 64MB cache and Serial ATA-6Gb/s interface. Western Digital declares 164MB/s – 171MB/s host to/from drive transfer rate as well as peak power consumption of WD Se 4TB is 9.5W. WD Se hard drive is based on enterprise-grade platform that ensures reliable operation in harsh large-scale environments over prolonged periods of time. At the same time, the drives are not tailored for maximum performance, which is why they are not going to be very expensive.

“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. 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,” said Richard E. Rutledge, senior vice president of WD’s datacenter storage business unit.

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.

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. 

WD’s Se hard drives, shipping in 2TB, 3TB and 4TB, (models: WD2000F9YZ, WD3000F9YZ, and WD4000F9YZ) are available through select distributors and resellers. Manufacturer’s suggested retail price (MSRP) for the WD Se hard drives range from $159.99 to $309.99. WD’s Se drives are covered by a five-year limited warranty.
