WD RE4-GP
Power-Saving Hard Drives
Available in capacities up to 2 TB, WD RE4-GP SATA hard drives
offer data-hungry organizations massive capacity with significant
power savings and lower cost of ownership compared to
competitors' standard enterprise-class drives. These drives are
designed with WD GreenPower TechnologyTM to deliver power
savings as the primary attribute and are equipped with 64 MB
cache, dual processors, and IntelliPowerTM, a fine-tuned balance
of spin speed, transfer rate, and caching algorithms designed to
deliver both significant power savings and solid performance.
