Raid and Power Managment in Server 2003

Hello

I have a raid-5 array in Windows Server 2003 which, is working fine.

Having been thinking about the power consumption and HDD life, I was wondering about using the Windows Power Management to power down the HDD’s after 30 min as they’re not used 24/7.

Would this cause any issues with the raid-5 array at all?

Thank you.
