My Mac Pro is Slow....why?

[covrc]

Hi All,
I have a situation here with my system and wonder if anyone might help me out? I am very new to all this configuring and have done my best to use the feedback from people on this site to help get up and running.

After my computer has been asleep over night or sitting idle for while, when I open finder and go to my Data Drive (Two 2TB Caviar Black in RAID 0. This is where I have all my working folders and files), it can take as long as a minute for the folder full of images I am looking for to open up, why is this?
Once the drives are running they are fast, but to ramp up is very slow almost a minute sometimes.....why?

I have the following setup now.

MacPro 2009 2.66 Quad
12Gb RAM

OCZ SSD 120GB Vertex SSD2 1VTX
Boot Drive and programs (Photoshop, Lightroom) Currently using 35GB of the 120GB.

Bay#1 640 GB Caviar Blue
partitioned X3
250GB Scratch Disc for Photoshop CS4 and Lightroom
300GB Storage (not using at this time.)
80Gb as a back up bootdrive

Bay#2 1TB Samsung Spinpoint F3
Time Machine

Bay#3 2TB WD Caviar Blacks.
Bay#4 2TB WD Caviar Blacks
RAID 0
I only have 600GB used.

it is these drives that are slow spinning up. Sometimes 30 seconds to a minute.

I am wondering if you might have an idea as to why this is happening?
What do I have to check that I am or am not doing?

Thanks in advance.

30 seconds to spin up seems a little odd. I recall my blacks spinning up in less than 10 seconds for a two drive array.

What you can do to get rid of this error, however, is to prevent the drives from sleeping in the first place. You can do this in the energy saver system settings.

Energy Saver

Do you mean in the Mac System Preferences?

Yes.

hmm

Is this a common problem for Mac Pros with multiple drives etc?

I would think that it would spin up a lot faster than it does.

So, it has nothing to do with the RAID 0 or the scratch disc?

Thanks.

Hmmmm. Any other ideas.

Another thing to try

Note the time, and go to Applications->Utilities and open Console.app

Scroll back to the approximate time your machine came out of sleep, and see if anything looks likely on the log. You can also navigate down to the "kernel.log" in the left Console navigation pane, and see if anything is there.

Might give you some clues...
