| Posted by peep96, 08-05-2010, 01:07 PM | | Hey guys,
I was looking around online for hard drives for a RAID 10 array and came across WD's Green hard drives. They are supposed to save energy by switching RPMs to a lower level when idling. I just wanted to know if it is okay to build a raid 10 array using these drives?
Thanks in advance.

You are still much better off with normal drives. The energy savings in the long-run are very low.

| Posted by peep96, 08-05-2010, 04:41 PM | | What is/are the differences? I looked around and it looks like the capacity of the drives are larger, but is performance better with Blacks?

I don't think they are good for RAID, because they require couple seconds to spin up when they are idle. however they are pretty reliable, we have been using some of them for some months, non of them fail yet. for RAID suggest you use RE3 or RE4.
