Constellation ES gives you the power to choose

choicesLast week, Seagate announced availability of the Constellation ES enterprise 2TB hard drive.   The real story behind this product is here.

What is not mentioned much in the circles of discussion around this drive is PowerChoice.

Seagate defines PowerChoice as…

“PowerChoice enables the host to tailor the drive’s power savings settings for performance and power consumption via mode pages (SAS) or Set Features commands (SATA). This configuration flexibility ensures that users can specify the optimal idle time thresholds (that is, how long the drive’s command queue is empty) for their particular storage applications. Users can choose to let the drive control PowerChoice itself through default timers, or they can disable PowerChoice altogether.”

How does it differ from what else it out there in terms of enterprise drive power consumption?

WD says, “Active Power Management is a feature on WD drives with GreenPower Technology that “monitors work load and automatically invokes idle mode whenever possible to further reduce unnecessary power consumption.”

It sounds like the difference is choice or no choice…

…you choose.
