Welland's innovative enclosure for external drives , the GreenStar series features the active power saving function by a simple and easy way. Unlike other external enclosures which will deliver 100% power consumption after power-on , the GreenStar offers a automatic power control to reduce power consumption step by step according to the read/write status of the external drives. The maximum reduction of electricity is to deliver maximum 7% power consumption to the external drives when there is no read/write access to the drives.

Sometimes the drives works with high rotational speed , e.x. 7200RPM drives , although the faster performance is perferred , but the higher working temperature and noise is not avoidable. As mentioned the power saving function reduces automatically the power consumption when no read/write access , the GreenStar series can lower operating temperatures for increased reliability of external drives. Users or gamers who require lower power consumption , cool and quiet operation for external drives , the GreenStar series is the ideal and perfect device.
