• Western Digital claims spinning down hard drives no longer cripple application performance
• WD’s solution offers lower storage power consumption without sacrificing consistent response times
• Reduced drive power usage allows more storage capacity inside existing rack limits

Western Digital (WD) has developed a new power-optimized drive technology which allows hard disks to spin down without causing major performance penalties.
