Folks,

I am after some information on whether or not performance will be adversely impacted by mixing drives of different size in a DP.
All drives are SAS, 15K RPM however 10 are 450GB and 5 are 600GB.
I was looking to create 3x RAID5 4+1 RGs in this pool.

I am of the understanding that there will be a small performance hit due to the higher seek times I assume on the 600GB disks.
I however do not belive that this alone is a big enough issue not to combine these disks in the pool.
Any advice would be appreciated.

Wayne
